GE IC693MDL940F Relay Output Module

Configured for discrete load switching and physical contact isolation in Series 90-30 PLC platforms, the GE Fanuc IC693MDL940F (IC693MDL940 Relay Output Module) provides direct physical/electrical execution.

Hardware Specifications

Backplane Bus Communication Velocity & I/O Isolation

The module interfaces directly with the Series 90-30 backplane bus, utilizing optocoupler isolation to ensure stable communication velocity and system logic execution. Signal lines pass across high-speed optical barriers rated for 1500 V RMS to prevent field electrical noise from compromising internal CPU functions. The discrete outputs are structured into 4 independent isolated groups, optimizing I/O density scaling while providing channel group galvanic separation to eliminate cross-talk during concurrent AC and DC switching cycles.

Frequently Asked Questions

Q: Does the IC693MDL940F module include internal current protection fuses for field wiring circuits?

A: No. The module does not contain internal fusing. External fuses must be installed on individual point lines or commons to protect internal relay contacts from overcurrent conditions.

Q: What are the backplane current draw requirements for the IC693MDL940F hardware?

A: The module draws 7 mA from the internal +5 VDC backplane bus and 135 mA from the +24 VDC relay power bus during full load activation.

Field Installation Guidelines

1. Disconnect main supply power to the PLC rack and field devices before inserting or removing the output module.
2. Align the module card with the designated baseplate slot and push firmly until the rear connector latches securely into the backplane.
3. Wire field output loads to the removable terminal block assembly, maintaining current limits within 2 A per point and 4 A per common terminal.
4. Route AC and DC field output cables in separate grounded metal conduits away from low-voltage DC logic and communication lines to prevent inductive noise interference.
