GE IC630MDL380 Relay Output Module

Configured for discrete load switching in Series 90-30 PLC systems, the GE IC630MDL380 ( IC630MDL380 Relay Output Module) provides direct physical execution for field control circuits.

Hardware Specifications

Backplane Bus & Deterministic Logic Execution

The module operates over the backplane bus communication system, transferring discrete state bits between the CPU processor sweep and physical output relays. Deterministic logic updates ensure output coil activation aligns precisely with programmed task intervals. High I/O density scaling allows 16 isolated logic circuits to reside within a compact single-slot chassis footprint, maintaining strict electrical isolation between low-voltage internal logic and external high-voltage field wiring.

Frequently Asked Questions

Q: Can this relay output module be hot-swapped while the PLC rack is powered?

A: No. Power to the rack backplane and external field circuit supply must be disconnected before inserting or removing the module to prevent electrical arcing and backplane logic corruption.

Q: What is the maximum continuous current rating for a single output circuit?

A: Each individual circuit supports a maximum continuous current of 4 A across the operating range of 5 to 265 VAC or 5 to 265 VDC. Overall module current capacity must adhere to system thermal derating guidelines.

Field Installation Guidelines

1. Ensure the PLC rack power supply is completely de-energized before mounting the module into the backplane slot.
2. Strip field conductor insulation according to standard terminal block specifications, maintaining minimum 5 mm wire strip length.
3. Wire the field load circuits to the corresponding Normally Open terminal points, ensuring external surge suppression diodes or RC snubbers are installed across inductive loads.
4. Verify field wiring insulation ratings exceed 300 VAC/VDC to maintain compliance with channel isolation standards.
5. Tighten terminal block screws to the manufacturer recommended torque spec (0.5 to 0.6 Nm) and secure standard shield grounding at the enclosure entry point.
