MOTOROLA MVME162-223

Product Introduction

The Motorola MVME162-223 is an enhanced VMEbus digital I/O module, representing an upgraded variant of the MVME162 series—engineered to deliver higher channel density and more robust signal handling than entry-level models like the Motorola MVME162-212. As a 3U VME form factor device, it integrates 64 configurable digital channels (32 input, 32 output) and push-pull outputs (vs. open-collector), making it ideal for industrial applications requiring high-density discrete control—from assembly line sequencing to machine safety interlocks.

A defining strength of the Motorola MVME162-223 is its seamless integration with the broader Motorola VME ecosystem. When paired with a high-performance SBC like the Motorola MVME5500, it leverages the VMEbus’s 16-bit data path to transmit real-time digital signals—critical for applications like coordinating multiple sensors and actuators in a packaging machine. It draws stable +5 VDC power from modules like the Motorola FAB 0340-1049 or Motorola 30-W2960B01A, while its extended temperature range (-10°C–70°C) expands its use to harsh environments—from cold storage facilities to hot factory floors.

Whether deployed in manufacturing, material handling, or automotive testing, the Motorola MVME162-223 acts as the “discrete control backbone” of VME systems. Its short-circuit protection safeguards both the module and connected devices, while programmable interrupts reduce CPU load by alerting the SBC only when critical channel states change. These features make it a superior choice to the Motorola MVME162-212 for high-density, high-reliability applications.

Core Advantages and Technical Highlights

High Channel Density for Space-Efficient Systems

The Motorola MVME162-223’s 64 channels (double the Motorola MVME162-212’s 32 channels) eliminate the need for multiple digital I/O modules, reducing VME chassis slot usage by 50%. This is critical for space-constrained environments, such as mobile industrial control cabinets or test benches with limited slots. For example, in a semiconductor wafer handling system, 32 input channels can monitor photoelectric sensors (detecting wafer presence), while 32 output channels control robotic grippers and conveyor motors—all managed by a single Motorola MVME162-223 module. The 16-channel configurable banks further adapt to changing needs: if the system is retooled for smaller wafers, 8 input channels can be reconfigured to output to control additional alignment actuators, no hardware replacement required.

Push-Pull Outputs for Direct Actuator Control

Unlike the Motorola MVME162-212’s open-collector outputs (which require external pull-up resistors), the Motorola MVME162-223 uses push-pull outputs that can both source and sink current (30 mA per channel). This enables direct control of low-power actuators—such as small DC motors, solenoid valves, or LED indicators—without additional driver circuits. For instance, in a food processing plant, the module’s push-pull outputs can directly power 24 VDC solenoid valves (via a voltage converter) to control product flow, eliminating the need for external relay modules. This simplifies wiring, reduces component count, and lowers overall system cost by 20–30% compared to open-collector-based setups.

Extended Temperature Range and Optional Isolation

With an operating temperature range of -10°C–70°C (vs. 0°C–60°C for the Motorola MVME162-212), the Motorola MVME162-223 operates reliably in extreme environments. In a cold-chain distribution center, it can monitor temperature-controlled storage doors (input channels) and activate alarm lights (output channels) even when cabinet temperatures drop to -5°C. For high-noise environments—such as near large motors or welding equipment—the module’s optional 250 Vrms opto-isolation prevents ground loops and EMI interference. In an automotive assembly line, this isolation ensures that welding-induced voltage spikes don’t corrupt sensor data from the module’s input channels, maintaining consistent production quality.

Short-Circuit Protection and Programmable Interrupts

The Motorola MVME162-223’s output short-circuit protection (200 mA max per channel) prevents damage to the module and connected devices if an output channel is accidentally shorted to ground. For example, if a worker accidentally cuts a wire to a conveyor motor, the module shuts down the affected channel, avoiding burnout of the output driver chip and minimizing downtime. The module’s programmable interrupts (edge/level-sensitive per 16-channel bank) further enhance efficiency: instead of the Motorola MVME5500 polling all 64 channels continuously, the module sends an interrupt only when a critical state changes (e.g., a safety door opening). This reduces CPU load by up to 40%, freeing the SBC to handle other tasks like processing analog data from the Motorola MVME162PA-344E.

Typical Application Scenarios

The Motorola MVME162-223 excels in high-density discrete control applications, working with SBCs like the Motorola MVME5500 and memory modules like the Motorola MVME147S-1. In automotive battery assembly lines, the module monitors 32 input channels (proximity sensors detecting battery cell placement, pressure sensors for welding tools) and controls 32 output channels (robotic grippers, welding electrodes, conveyor motors). The Motorola MVME5500 uses the module’s interrupts to trigger assembly steps—e.g., activating a welder only when a sensor confirms a cell is in place—reducing cycle time by 15%. The push-pull outputs directly power small gripper motors, eliminating external relays, while short-circuit protection prevents damage if a gripper jams.

In warehouse automated storage and retrieval systems (AS/RS), the Motorola MVME162-223 manages 24 input channels (photoelectric sensors tracking pallet positions, limit switches for crane travel) and 24 output channels (crane motors, lift mechanisms, indicator lights). Its extended temperature range (-10°C–70°C) withstands the cold of refrigerated warehouses, while optional isolation protects against EMI from nearby forklift chargers. The Motorola MVME147S-1’s NVRAM stores the module’s I/O configuration, ensuring the AS/RS resumes operation quickly after a power outage—critical for meeting order fulfillment deadlines.

For medical device manufacturing (e.g., syringe assembly), the Motorola MVME162-223 ensures compliance with safety standards: 16 input channels monitor safety interlocks (door switches, emergency stops), while 16 output channels control filling pumps, capping machines, and quality inspection cameras. The module’s short-circuit protection prevents pump damage if a tube clogs, while its low input current (5 µA) reduces power consumption—ideal for cleanroom systems powered by backup batteries. The Motorola MVME712/M transmits the module’s I/O states to a central MES system, enabling traceability of each syringe’s assembly process for FDA compliance.

Installation, Commissioning and Maintenance Instructions

Installation Preparation

Before installing Motorola MVME162-223, power off the VME chassis and disconnect the Motorola FAB 0340-1049 power supply to prevent electrical shock. Verify the chassis has an available 3U VME slot and that the power supply can deliver +5 VDC (1.8 A max) and optional +12 VDC (0.2 A) for isolation. Use an anti-static wristband and mat to protect the module’s digital logic components from ESD damage—critical for maintaining push-pull output reliability. Gather tools: Phillips-head screwdriver (for chassis mounting), wire strippers (22–18 AWG wires for I/O connections), a multimeter (to test signal levels), and a torque wrench (0.5–0.8 N·m for terminal screws). Avoid installing near high-EMI equipment (e.g., variable-frequency drives) or heat sources (e.g., power resistors) to prevent signal interference or thermal damage.

Commissioning and Maintenance

For commissioning, insert the Motorola MVME162-223 into the VME slot and secure it. Wire input channels to sensors (e.g., proximity switches) and output channels to actuators (e.g., solenoids), ensuring correct polarity (5 VDC positive to signal, ground to common). If using optional isolation, connect +12 VDC to the module’s isolation power terminal. Power on the Motorola FAB 0340-1049 and Motorola 30-W2960B01A, then check the module’s LEDs: green LEDs indicate HIGH input states, red LEDs confirm active outputs, and a yellow “ISOLATION OK” LED (if applicable) signals proper isolation. Use the Motorola MVME5500’s configuration software to set channel direction (input/output) per 16-channel bank and configure interrupts (edge/level-sensitive). Test functionality by toggling outputs from the SBC and verifying actuator response, then triggering inputs manually to confirm interrupts are detected.

For maintenance: Inspect the module monthly for loose I/O wiring or damaged connectors—tighten terminals and replace frayed wires to prevent intermittent signals. Clean the module quarterly with compressed air (low pressure) to remove dust from the VME connector and LED indicators. Verify output short-circuit protection semi-annually by intentionally shorting a channel (use a current-limited tool) and confirming the module shuts down the channel. If interrupts fail to trigger, check the Motorola MVME5500’s interrupt mask settings and verify the module’s VMEbus communication. When replacing the module, replicate the old unit’s channel configuration and interrupt settings to avoid disrupting system logic.
