MOTOROLA MVME-110-1
Product Introduction
The Motorola MVME-110-1 is a legacy entry-level embedded controller from Motorola’s iconic MVME series, engineered to deliver ultra-compact, cost-effective control for small-scale VMEbus-based industrial systems. As a 3U VME device, it occupies the “entry point” of Motorola’s controller lineup—ideal for applications that don’t require the processing power of mid-range models like the Motorola MVME-121 or Motorola MVME-147-023, such as simple sequential control or auxiliary equipment monitoring.
In automation architectures, the Motorola MVME-110-1 acts as a “micro-control node”: its MC68008 processor handles basic logic tasks (e.g., on/off sequencing for pumps), a single serial port connects to legacy HMIs or simple sensors, and 6 digital I/O channels manage low-power actuators (e.g., indicator lights, small relays). For example, in a small water treatment plant’s auxiliary pump system, the Motorola MVME-110-1 can monitor tank level sensors (digital inputs) and activate/deactivate pumps (digital outputs) via preprogrammed logic—all without the complexity of larger controllers. Today, the Motorola MVME-110-1 remains a reliable solution for maintaining legacy systems in sectors like small manufacturing, laboratory testing, and municipal auxiliary infrastructure—where upgrading to modern controllers would disrupt proven, low-cost workflows.
Core Advantages and Technical Highlights
Ultra-Low Power Consumption for Compact Systems: The Motorola MVME-110-1 operates on a single +5 VDC supply and draws just 0.6 A typically—30% less power than the Motorola MVME-121. This makes it ideal for space-constrained, power-limited setups, such as portable test equipment or battery-backed emergency control panels. In a mobile laboratory’s temperature monitoring system, the module’s low power draw extends battery life during off-grid operations, while its compact 3U form factor fits in small enclosures—eliminating the need for bulky power supplies.
Cost-Effective Basic Control for Small Applications: The Motorola MVME-110-1’s simplified design (MC68008 processor, minimal I/O) reduces hardware costs by 40–50% compared to mid-range controllers. For a local bakery’s dough mixer control system, the module uses its 3 digital inputs to monitor safety interlocks (e.g., door closure) and 3 outputs to control mixer start/stop and alarm lights—avoiding overpaying for unused features like multiple serial ports or high-speed processing. This affordability makes it a go-to choice for small businesses with tight automation budgets.
Legacy Compatibility for Long-Term System Reliability: The Motorola MVME-110-1’s support for VMEbus 1.0 and TTL/CMOS devices ensures seamless integration with decades-old industrial equipment. For instance, a 1990s-era packaging machine with TTL-based limit switches can connect directly to the module’s digital inputs, avoiding costly signal converters. The battery-backed SRAM also retains configuration data during power outages—critical for unattended systems like warehouse ventilation controls, where manual reconfiguration after outages would cause downtime.
Typical Application Scenarios
The Motorola MVME-110-1 excels in ultra-small-scale, low-complexity automation. In a regional hardware store’s inventory sorting system (paired with a Motorola MVME162-01 for extra I/O), the Motorola MVME-110-1 manages a small conveyor: its serial port connects to a barcode scanner (to read product IDs), 3 digital inputs monitor conveyor jam sensors, and 3 outputs control conveyor speed (low/high) and a jam alarm. The module’s basic diagnostic firmware alerts staff to sensor failures, preventing costly conveyor damage.
In a university chemistry lab’s sample heating system, the Motorola MVME-110-1 acts as a standalone controller: its serial port links to a temperature sensor (0–5 VDC output), 2 digital inputs monitor heater overheat switches, and 2 outputs activate the heater and a status LED. The parallel port prints test timestamps to a small lab printer, ensuring compliance with experiment documentation requirements. For the lab, the Motorola MVME-110-1 avoids the $8k cost of upgrading to a modern PLC, as it reliably handles daily heating cycles with <1% annual downtime.

Installation, Commissioning and Maintenance Instructions
Installation preparation: Before installing Motorola MVME-110-1, power off the VME chassis and verify compatibility with +5 VDC (1.0 A max; no ±12 VDC needed) to prevent electrical shock. Use an anti-static wristband and mat to protect the module’s MC68008 processor and I/O circuits from ESD damage. Gather tools: Phillips-head screwdriver (chassis mounting), 22–18 AWG wires (digital I/O), serial/parallel cables, torque wrench (0.5–0.8 N·m for terminals), and a multimeter (to test TTL signal levels). Avoid installing near high-EMI sources (e.g., small fans or power supplies) to prevent serial signal corruption.
Maintenance suggestions: For routine care, inspect Motorola MVME-110-1’s LEDs monthly—blinking “TX/RX” confirms serial communication, while green “I/O active” LEDs indicate proper sensor/actuator connectivity. Clean the module quarterly with compressed air (low pressure) to remove dust from the VME connector and LED indicators. Every 18 months, replace the SRAM backup battery (3V lithium) to avoid configuration data loss. If the serial port fails, use the module’s hardware reset switch to troubleshoot; replace the module if I/O drivers malfunction. Store a spare EPROM with firmware to minimize downtime during repairs.
