MOTOROLA MVME162-212

Product Introduction

The Motorola MVME162-212 is a versatile VMEbus digital I/O module, engineered to handle discrete signal acquisition and control in industrial automation systems—serving as a critical link between host SBCs (like the Motorola MVME5500) and field devices such as sensors, relays, and indicator lights. As a 3U VME form factor device, it offers 32 configurable digital channels (16 input, 16 output by default) that can be reconfigured in 8-channel banks, making it adaptable to diverse I/O needs without requiring multiple modules.

A key strength of the Motorola MVME162-212 is its seamless integration with the 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—essential for applications like assembly line sequencing or machine safety interlocks. It draws stable +5 VDC power from modules like the Motorola FAB 0340-1049 or Motorola 30-W2960B01A, and its passive cooling design ensures reliability in space-constrained VME chassis where airflow is limited.

Whether deployed in manufacturing, packaging, or material handling systems, the Motorola MVME162-212 delivers consistent discrete I/O performance. Its programmable interrupts reduce CPU load by alerting the SBC only when channel states change (e.g., a sensor detecting a part), while output latch protection retains critical control signals during brief power dips—minimizing costly process disruptions. These features make it a foundational component for legacy VME systems requiring flexible, low-cost digital signal management.

Core Advantages and Technical Highlights

Configurable I/O Channels for Flexible System Design

The Motorola MVME162-212’s 32 channels (configurable in 8-channel banks) eliminate the need for separate input and output modules, reducing VME chassis slot usage by up to 50% compared to fixed-function digital I/O devices. For example, in a packaging machine control system, 8 channels can be set to input (monitoring photoelectric sensors for package presence) and 24 to output (controlling conveyor motors, sealers, and indicator lights)—all via software configuration, no hardware modifications needed. This flexibility adapts to changing application needs: if the machine is retooled for a new product, the Motorola MVME162-212’s channel direction can be adjusted remotely via the Motorola MVME5500 SBC, avoiding downtime for module replacement.

TTL/CMOS Compatibility for Broad Device Integration

The Motorola MVME162-212’s TTL/CMOS-compatible inputs and outputs ensure seamless connectivity with thousands of industrial devices—from low-cost photoelectric sensors (5 VDC logic) to legacy relay drivers. Its input voltage thresholds (0–0.8 VDC LOW, 2.0–5.5 VDC HIGH) and 20 mA sink outputs match industry-standard discrete components, eliminating the need for signal level converters. For instance, in an automotive parts assembly line, the module’s inputs can directly read TTL-level signals from proximity sensors, while its outputs drive 5 VDC relays to activate robotic grippers—simplifying wiring and reducing component count.

Programmable Interrupts for Efficient CPU Utilization

Unlike basic digital I/O modules that require the SBC to poll channels continuously (wasting processing power), the Motorola MVME162-212 supports programmable interrupts per 8-channel bank. The module only sends an interrupt to the Motorola MVME5500 when a channel state changes (e.g., a safety door opening), allowing the SBC to focus on other tasks like process control or data logging. This reduces CPU load by up to 30% in systems with multiple I/O modules, ensuring the Motorola MVME5500 can handle compute-intensive tasks (e.g., running PID loops for analog modules like the Motorola MVME162PA-344E) without being bottlenecked by digital I/O polling.

Output Latch Protection for Uninterrupted Operation

The Motorola MVME162-212’s output latch protection retains the last valid output state during brief power fluctuations (up to 100 ms), a common issue in industrial environments with heavy machinery. For example, in a food processing plant, if a temporary power dip occurs while the module is outputting a signal to keep a mixing valve open, the latch ensures the valve remains open—preventing batch contamination from unexpected shutdowns. This feature eliminates the need for external UPS systems for digital control signals, reducing overall system cost while enhancing reliability.

Typical Application Scenarios

The Motorola MVME162-212 excels in discrete control applications, working with SBCs like the Motorola MVME5500 to manage field devices. In automotive assembly line sequencing, the module monitors 12 input channels (proximity sensors detecting the presence of engine components) and controls 20 output channels (actuating robotic arms, bolt tighteners, and part conveyors). The Motorola MVME5500 uses the module’s programmable interrupts to trigger sequence steps only when sensors confirm a component is in place—reducing cycle time by ensuring no step starts prematurely. The module’s TTL compatibility allows direct connection to the line’s existing sensors and relays, avoiding costly rewiring.

In pharmaceutical packaging, the Motorola MVME162-212 ensures compliance with safety and quality standards: 8 input channels monitor safety interlocks (e.g., door switches on packaging machines), while 8 output channels control emergency stops and alarm lights. If a safety door is opened, the module sends an interrupt to the Motorola MVME5500, which immediately halts the machine via the module’s output channels. Its output latch protection retains the “stop” signal during power dips, preventing the machine from restarting accidentally—critical for meeting FDA regulations. The passive cooling design also fits in the cleanroom-compatible VME chassis, where fans are prohibited to avoid particle contamination.

For material handling systems (e.g., warehouse conveyors), the Motorola MVME162-212 manages 16 input channels (photoelectric sensors tracking pallet positions) and 16 output channels (controlling conveyor motors and diverter gates). The Motorola MVME5500 uses the module’s digital inputs to optimize pallet routing, while the outputs adjust conveyors in real time. The module’s low power consumption (0.6 A typical at +5 VDC) makes it suitable for battery-backed mobile material handling carts, where the Motorola 30-W2960B01A power distribution module ensures efficient power usage.

Installation, Commissioning and Maintenance Instructions

Installation Preparation

Before installing Motorola MVME162-212, 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 VME backplane can supply +5 VDC (1.0 A max) to the module. Use an anti-static wristband and mat to protect the module’s digital logic components from ESD damage—critical for maintaining TTL signal integrity. Gather tools: Phillips-head screwdriver (for chassis mounting), wire strippers (to prepare 22–18 AWG wires for I/O connections), and a multimeter (to test signal levels). Avoid installing near high-noise equipment (e.g., variable-frequency drives) or heat sources (e.g., power supplies) to prevent EMI interference or thermal damage.

Commissioning and Maintenance

For commissioning, insert the Motorola MVME162-212 into the VME slot and secure it. Wire input channels to field sensors (e.g., photoelectric switches) and output channels to actuators (e.g., relays), ensuring correct polarity (5 VDC positive to signal, ground to common). 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. Use the Motorola MVME5500’s configuration software to set channel direction (input/output) for each 8-channel bank and enable interrupts for critical channels (e.g., safety interlocks). Test functionality by toggling outputs from the SBC and verifying actuator response, then triggering inputs manually and confirming the SBC receives state changes.

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 (avoids overheating and ensures LED visibility). Verify TTL signal levels semi-annually using a multimeter: input LOW should be <0.8 VDC, input HIGH >2.0 VDC; output sink current should not exceed 20 mA per 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 (direction, interrupts) to avoid disrupting system logic.
