GE VMIVME-2210

1. Core Architecture

  • Function: 64-channel relay output board for industrial control systems, providing high-density signal switching and circuit control .
  • Relay Type: Magnetic latching relays (default) or non-latching (optional), with Form C (SPDT) contacts .
  • Channels: 64 independent SPDT relays, each offering Normally Open (N.O.), Normally Closed (N.C.), and Common contacts .
  • Contact Configuration:
    • Form A (SPST): Via N.O. + Common (64-core cable) .
    • Form B (SPST): Via N.C. + Common .
  • Switching Capacity: 2.0A per channel at 250V AC/30V DC .
  • Isolation: Optical isolation (≥1,500V channel-to-bus) for EMI immunity .

2. Control & Diagnostics

  • Latching Behavior:
    • Latching version: Relays retain state during power loss until reset .
    • Non-latching version: Relays reset to default position (N.O. open, N.C. closed) on power cycle .
  • Built-in Test (BIT):
    • Uses N.C. contacts to monitor relay health and detect faults (e.g., open circuits) .
    • Reports status via front-panel LEDs and VMEbus interrupts (IRQ1–IRQ7) .
  • Response Time: ≤7 ms for relay actuation .

3. Electrical & Environmental

  • Power Requirements:
    • Logic: +5VDC ±5% (VMEbus supply).
    • Relay Coils: +24VDC (external source) .
  • Compliance: ANSI/IEEE STD 1014-1987 VMEbus standards .
  • Operating Temperature: 0°C to +60°C (industrial range) .
  • Humidity: 5–95% non-condensing .

Functional Features

  1. High-Density Switching:
    • 64 SPDT relays support simultaneous control of multiple circuits (e.g., motor starters, safety interlocks) .
    • Alternate contact configurations (Form A/B) reduce wiring complexity .
  2. Fault Tolerance:
    • Latching relays ensure state persistence during power outages, critical for fail-safe systems .
    • BIT diagnostics provide real-time health monitoring and isolate faulty relays without system downtime .
  3. VMEbus Integration:
    • A16/A24 addressing and D08/D16/D32 data transfers for seamless PLC/CPU communication .
    • Hardware-level protection prevents relay actuation during power surges .

Application Scenarios

Domain Use Cases Key Capabilities Utilized
Industrial Automation Safety interlocks in robotic assembly lines, conveyor belt controls 64-channel density; latching relays for state retention .
Energy Systems Circuit breaker control in substations, generator excitation systems 2.0A switching capacity; optical isolation for grid noise .
Test & Measurement Automated test equipment (ATE) signal routing, load bank switching BIT diagnostics; Form A/B flexibility .
Transportation Rail signaling, crane control systems Non-latching option for auto-reset during power restoration .

Technical Differentiation

Integration Notes

  • Wiring: Two 96-pin DIN connectors for contact outputs .
  • Software Support: Compatible with VxWorks, QNX, and GE Proficy® PLCs .
  • Ordering Variants:
    • VMIVME-2210-XXX: Latching version (default).
    • VMIVME-2210-NL: Non-latching option .
  • Legacy Compatibility: Plug-and-play with GE VMIC CPUs (e.g., VMIVME-7750) .
