Technical Specifications:
  • Inputs: Bridge temp, fan status, field breaker aux contact
  • Outputs: 8 programmable Form-C relays
  • Architecture: TMR-compatible
  • SOE: Millisecond event stamping
  • Backplane: EX2100e rack
  • Temp: -20 °C to +60 °C
    Functional Features:​ Isolated relay outputs; local sequence-of-events; no active control loop—pure interface; LED per relay.
    Materials & Structure:​ FR-4 with conformal coat; plug-on VME-style header; DIN terminal strip.
    Working Principle:​ Controller logic asserts optical isolator; transistor drives sealed relay coil; contact closes to annunciator or interposing relay.
    Installation Requirements:​ Seat in EX2100e aux slot; ground shield to cubicle; separate thermocouple from relay wires.
    Precautions:​ Relay life finite—avoid chatting; verify Form-C common not tied to 125 V DC unprotected.
