    • Output: 24 V DC relay or transistor, 5 A contact rating
    • Bus: Genius Bus (Mark V) or Series One (Mark VI)
    • SOE resolution: Sub-millisecond time-stamping
    • Backplane power: +5 V DC, < 4 W
    • Temp range: 0 °C to +60 °C operating
    • Construction: FR-4 multilayer, shielded metal front, gold-plated military connectors, sealed magnetic-latching relays
  • Functional Features: Per-channel debounce, wire-break detection, AND/OR/timer logic on board, redundant pairing support, 16 dual-color status LEDs.
  • Application Scenarios: Valve limit sensing, pump start interlocks, SOE event capture, solenoid drive in turbine auxiliary systems.
  • Installation Requirements: Insert in Mark V I/O rack or Mark VI I/O box, set node address via rotary switch, terminate field wiring on isolated side.
  • Usage Notes: Do not mix TTL and 24 V field inputs on same module group without jumper change; SOE accuracy depends on synchronized bus clock.
