MOTOROLA MVME-167

Product Introduction

The Motorola MVME-162-523 is a legacy high-density digital I/O module from Motorola’s MVME-162 series, engineered to expand discrete control capabilities for VMEbus-based automation systems—with a focus on seamless integration with the Motorola MVME-167 SBC series. As a 3U VME device, it fills a critical niche between basic I/O modules (e.g., Motorola MVME-050 with 16 channels) and specialized high-voltage I/O cards, offering 32 TTL/CMOS-compatible channels to support large-scale sensor/actuator networks.

In automation architectures, the Motorola MVME-162-523 acts as a “scalable I/O expander” for Motorola MVME-167 SBCs: its 16 inputs monitor low-power devices (e.g., limit switches, photoelectric sensors), while 16 outputs control small actuators (e.g., relay coils, indicator lights). For example, in a manufacturing line using Motorola MVME-167-04B (16 built-in I/O), adding Motorola MVME-162-523 doubles the I/O capacity—enabling control of 32 additional conveyor section sensors/actuators without replacing the SBC. Today, it remains indispensable for maintaining legacy Motorola MVME-167-based systems in sectors like automotive assembly, packaging, and municipal utilities, where expanding I/O without full system overhauls is critical.

Core Advantages and Technical Highlights

High-Density I/O for Space Efficiency: With 32 channels in a single 3U VME slot, the Motorola MVME-162-523 delivers twice the density of Motorola MVME-050 (16 channels)—reducing chassis slot usage by 50% for large-scale I/O needs. In an automotive component plant’s assembly line, pairing Motorola MVME-167-32B with two Motorola MVME-162-523 modules provides 80 total I/O channels (16 from SBC + 32×2 from modules) in just 3 slots—avoiding the need for 5 slots with basic I/O modules. This compact design cuts wiring complexity by 30% and lowers chassis hardware costs by 25%.

Seamless Compatibility with Motorola MVME-167 Series: The Motorola MVME-162-523 is factory-calibrated to work with Motorola MVME-167 SBCs—sharing the same 3U form factor, VMEbus timing, and configuration tools. Unlike third-party I/O modules, it requires no custom driver development for MVME-167 variants: a Motorola MVME-167-01B (entry-tier SBC) can control Motorola MVME-162-523 via preloaded firmware, while upgrading to MVME-167-32B (high-end SBC) retains full I/O functionality. This compatibility eliminates 4–6 hours of driver integration time per module, critical for time-sensitive maintenance.

Robust Protection for Industrial Reliability: The Motorola MVME-162-523 includes hardware safeguards missing from basic I/O modules: overcurrent protection (per 8-channel bank) prevents damage from shorted outputs, while 2 kV ESD protection shields terminals from electrical surges (common in factory environments). In a packaging plant, if a conveyor motor’s wiring shorts to an output terminal, the module’s overcurrent circuit trips within 10 ms—protecting both the module and the Motorola MVME-167 SBC. This reliability reduces unplanned I/O-related downtime by 40% compared to unprotected modules.

Typical Application Scenarios

The Motorola MVME-162-523 excels in I/O-intensive, MVME-167-powered systems. In a regional beverage bottling plant using Motorola MVME-167-04B as the main controller:

The MVME-167-04B’s 16 built-in I/O channels manage critical tasks (e.g., filling valve control, emergency stops).

Two Motorola MVME-162-523 modules expand capacity: 32 inputs monitor bottle presence sensors (one per filling station), and 32 outputs activate conveyor section motors and “low stock” indicators.

The module’s EEPROM stores I/O configurations (e.g., debounce time for sensors), so if the MVME-167-04B is replaced with MVME-167-32B (for higher data logging), the I/O setup retains no reconfiguration—minimizing production downtime.

For the plant, this setup avoids the $30k cost of upgrading to a modern Ethernet I/O system, as Motorola MVME-162-523 seamlessly extends the legacy MVME-167 infrastructure while meeting daily production needs (10,000+ bottles per hour).

Installation, Commissioning and Maintenance Instructions

Installation preparation: Before installing Motorola MVME-162-523, power off the VME chassis and verify compatibility with Motorola MVME-167 series SBCs (check firmware version ≥ v1.5 for full support). Use an anti-static wristband and mat to protect the module’s I/O circuits from ESD—critical for TTL/CMOS components. Gather tools: Phillips screwdriver (chassis mounting), 22–18 AWG stranded wires (I/O connections), torque wrench (0.5–0.8 N·m for terminal blocks), 1kΩ pull-up resistors (for outputs), and a multimeter (to test TTL signal levels). Avoid installing near high-EMI sources (e.g., variable-frequency drives, welding equipment) to prevent I/O signal corruption—align module placement with MVME-167 SBCs for consistent grounding.

Maintenance suggestions: For routine care, inspect Motorola MVME-162-523’s LEDs monthly—green “active” LEDs confirm input signals; red “fault” LEDs alert to overcurrent or shorted outputs. Clean the module quarterly with compressed air (low pressure) to remove dust from the VME connector and LED indicators. Every 12 months, verify overcurrent protection functionality: intentionally short a test output (with a 1Ω resistor) to confirm the 8-channel bank trips within 10 ms. If an I/O channel fails, reassign a spare channel via the MVME-167’s configuration tool; replace the module if 3+ channels in the same bank malfunction. Store a backup EEPROM with I/O settings to minimize downtime during replacement.
