Functional Features Upgraded relay units, dry‑contact output, mixed AC‑DC load support, per‑channel LED indication, galvanic isolation, status feedback to CPU.
Application Scenarios High‑reliability auxiliary loop control, spare replacement for IC693MDL940, process plant auxiliary signal output.
Performance Parameters Relay actuation time ≤10ms Improved mechanical service life of relay contacts Single‑channel fault does not affect remaining channels Shock & vibration:Comply with IEC 60068
Structural Characteristics Standard Series 90‑30 plug‑in rack module Front‑panel per‑channel LED indicators Front‑side field wiring terminal block Backplane gold‑finger bus contact Internal high‑reliability relay array Mechanical locking latch
Working Principle Consistent with IC693MDL940. CPU transmits control signals over backplane bus, drives upgraded relay coils, dry contacts complete on‑off action for external loads. Physical isolation separates field and PLC logic circuit. LED displays channel working state.
Installation Requirements Install into Series 90‑30 rack slot. Implement standard protective ground. Correctly connect NO/NC terminals for field loads. Keep field power cables away from weak‑signal lines. Replace module only under rack power‑off condition, hot‑swap forbidden. Operate within rated temperature and humidity range.
Usage Notes Shall not surpass rated contact current and voltage. Equip arc‑suppression parts for inductive loads. Avoid excessive frequent switching. Periodically inspect LED and terminal connections. On‑site disassembly is prohibited. Avoid corrosive atmosphere and liquid splash.
