2. Control & Diagnostics

  • Status Monitoring: Per-channel LED indicators for relay state (energized/de-energized) .
  • Built-in Test (BIT):
    • Self-diagnostics verify relay coil integrity and contact functionality .
    • Fault reporting via VMEbus interrupts (IRQ1–IRQ7) .
  • Response Time: ≤10 ms (electromechanical); ≤1 ms (solid-state) .

3. Electrical & Environmental

  • Power Requirements: +5VDC ±5% (logic), +12V to +24VDC (relay coil drive) .
  • Operating Temperature: 0°C to +60°C (industrial standard) .
  • Humidity: 5–95% non-condensing .
  • Compliance: CE Mark, RoHS, and industrial EMC immunity (CISPR 22) .

Functional Features

  1. High-Reliability Switching:
    • Gold-plated contacts minimize arcing and extend lifespan (≥1 million cycles) .
    • Flyback diodes suppress voltage spikes during inductive load switching (e.g., solenoids, motors) .
  2. Flexible Configuration:
    • Programmable Latching/Non-Latching Modes: Sustains relay state during power loss (latching) or auto-resets (non-latching) .
    • Per-Channel Control: Independent activation via VMEbus writes .
  3. Fault Tolerance:
    • Watchdog Timer: Automatically de-energizes all relays on control system failure .
    • Short-Circuit Protection: Current-limiting circuits prevent damage during overloads .
