Motorola MVME-147SB-2

Product Introduction

The Motorola MVME-147-011 is a legacy industrial VMEbus Single Board Computer (SBC) designed as an entry-level solution for discrete control and basic data acquisition tasks—serving as the foundational model for the more feature-rich Motorola MVME-147-011A. Unlike its successor (which adds 2 extra serial ports and expandable DRAM), Motorola MVME-147-011 focuses on core functionality: a 20 MHz MC68030 processor, fixed 2 MB DRAM, and essential communication interfaces (EIA-232-D, Ethernet, SCSI) to support small-scale industrial systems.

In automation architectures, Motorola MVME-147-011 acts as a “compact control hub”: it executes basic control logic (e.g., on/off actuator control, sensor status monitoring) and communicates with peripheral modules like Motorola MVME-201 (digital input) via the VMEbus. For example, a small packaging plant uses Motorola MVME-147-011 to manage 2 conveyor belts—monitoring “package present” sensors via serial ports and logging production data to a SCSI hard drive. Its -30°C–75°C operating range and 3U form factor make it ideal for legacy systems like standalone manufacturing cells, regional utility monitoring stations, or laboratory test equipment—where cost and space efficiency matter more than advanced processing power.

Core Advantages and Technical Highlights

Cost-Effective Entry-Level Processing: Motorola MVME-147-011 delivers reliable 32-bit performance at a lower cost than its successor Motorola MVME-147-011A, making it suitable for budget-constrained users. Its 20 MHz MC68030 processor handles basic control tasks (e.g., simple PID loops for temperature control) without the excess capacity of higher-tier SBCs. A small water treatment plant uses Motorola MVME-147-011 to regulate a single pump’s speed based on tank level data—avoiding the $1,500+ premium for the MVME-147-011A’s extra features, which are unnecessary for the application.

Essential Communication Interfaces for Basic Connectivity: Motorola MVME-147-011 integrates 2 EIA-232-D serial ports, 10Base-T Ethernet, and SCSI-1—covering the core connectivity needs of small industrial systems. In a warehouse inventory setup, the SBC uses its Ethernet port to send daily inventory counts to a central office, while serial ports connect to 2 barcode scanners. This eliminates the need for external communication modules, reducing component count and setup time vs. using a processor-only board. Unlike generic SBCs, Motorola MVME-147-011’s interfaces are optimized for industrial reliability—with surge protection to withstand electrical interference in factory environments.

Ruggedness for Harsh Environments: Motorola MVME-147-011’s -30°C–75°C operating range exceeds the specs of consumer-grade SBCs (typically 0°C–40°C), enabling operation in extreme conditions. A frozen food storage facility uses Motorola MVME-147-011 to monitor temperature sensors (-25°C) and control refrigeration unit fans—maintaining reliable performance where Motorola MVME-147SA-1 (a later entry-level model) would fail due to cold-related component issues. Its 1.2 g vibration resistance also ensures stability in high-motion areas like near packaging machinery.

Typical Application Scenarios

In small-scale automotive component testing, Motorola MVME-147-011 controls a standalone torque test rig. It connects to a Motorola MVME-177-003 (analog input module) to measure torque values (4–20mA) and uses a digital output module to stop the test if values exceed limits. The SBC’s Ethernet port transmits test results to a lab computer, while the SCSI interface stores 1 month of historical data (2 MB DRAM buffers data temporarily). Motorola MVME-147-011’s 8 W typical power consumption makes it suitable for the rig’s battery-backed backup system, ensuring testing continues during short power outages.

For regional weather station monitoring, Motorola MVME-147-011 is installed in an outdoor enclosure to track temperature, humidity, and wind speed. It collects sensor data via 1 serial port (connected to a multi-sensor module) and sends hourly updates to a central weather server via Ethernet. The battery-backed 4 KB SRAM preserves configuration data (e.g., sensor calibration values) during power outages, while the -30°C operating range withstands winter temperatures. Motorola MVME-147-011’s compact size fits in the station’s small enclosure, avoiding the need for a larger chassis.

Installation, Commissioning and Maintenance Instructions

Installation preparation: Before installing Motorola MVME-147-011, verify the VMEbus chassis has a 3U slot and supports A24/D16 addressing. Confirm the power supply provides +5V DC (±5%) and +12V DC (±10%)—use a multimeter to avoid voltage spikes that damage the MC68030 processor. Gather tools: anti-static wristband (protects sensitive components), torque screwdriver (0.3 N·m for mounting), and a laptop (for OS configuration via serial port). If adding a coprocessor, align it with the SBC’s socket, press gently until seated, and secure with the provided clip.

Maintenance suggestions: For daily upkeep, check Motorola MVME-147-011’s LEDs—steady power and blinking processor/Ethernet lights indicate normal operation. Run BIST monthly by power-cycling the SBC; replace the module if memory/EPROM errors occur. Clean the SBC’s vents quarterly with compressed air (20 PSI max) to prevent overheating. If the Ethernet port fails, inspect the cable (replace with Cat5 shielded cable) and reconfigure the IP address via the serial console. Store spare Motorola MVME-147-011 units in anti-static bags (15°C–25°C, 40%–60% humidity) to preserve EPROM/firmware integrity.
