GE IC693MDL940H Output Module

The GE Fanuc IC693MDL940H, also cataloged as the IC693MDL940 Relay Output Module, operates as a dedicated hardware component for discrete load switching and physical circuit isolation within Series 90-30 PLC platforms.

Hardware Specifications

Backplane Bus Architecture & I/O Density Execution

Designed for reliable operation across Series 90-30 backplane structures, the module optimizes I/O density scaling while maintaining high electrical isolation between control logic and field circuits. Communication signals pass through high-speed optocouplers to isolate internal logic from backplane noise and field transients. The dual-group output layout provides galvanic isolation between distinct channel groups, enabling deterministic switching execution and preventing cross-talk across independent AC and DC load circuits.

Frequently Asked Questions

Q: How does the revision H hardware update affect system compatibility and module installation?

A: Revision H designates an updated hardware design that maintains full functional and physical backward compatibility with previous IC693MDL940 module revisions.

Q: Can AC and DC load voltages be switched simultaneously on the same physical module?

A: Yes. The 16 channels are divided into two electrically isolated groups of 8 points with independent commons, allowing one group to switch AC voltage while the second group handles DC loads.

Field Installation Guidelines

1. Isolate main power to the PLC rack and turn off field voltage supplies prior to mounting or wiring the module.
2. Slide the module into the designated I/O slot of the Series 90-30 baseplate, pushing firmly until the rear backplane connector latches.
3. Wire field output loads to the removable terminal block, ensuring current limits do not exceed 2 A per point or 4 A per common terminal.
4. For inductive loads, install external transient suppression devices (flyback diodes for DC loads or RC snubbers for AC loads) across the field device terminals to protect relay contacts.
