GE Fanuc IC693MDL655E Series 90-30 Fast Input Module
The GE Fanuc IC693MDL655E, also cataloged as the IC693MDL655 Fast Input Module, operates as a dedicated hardware component for high-density discrete signal processing within Series 90-30 PLC platforms. Installed in any standard I/O slot of a 5-slot or 10-slot baseplate, the unit processes 32 fast discrete 24 VDC input channels arranged in four isolated groups to monitor field devices such as limit switches, pushbuttons, and proximity sensors.

Backplane Bus Communication Velocity & I/O Density Scaling
The IC693MDL655E executes high-speed input scan updates directly across the parallel backplane bus, maintaining optimal backplane bus communication velocity during real-time PLC sweep operations. Optical isolation barriers protect backplane logic lines from field-side ground loops and transient noise. Concentrating 32 high-speed positive/negative logic input channels into a single backplane slot facilitates efficient I/O density scaling while reducing overall control cabinet footprint.
Frequently Asked Questions
Q: What type of wiring connection is required to interface field sensors with the IC693MDL655E?
A: The front panel utilizes two 24-pin Fujitsu connectors (FCN-365P024-AU) instead of standard screw terminals. Field connections require pre-wired cables such as the IC693CBL327 for Groups A/B and IC693CBL328 for Groups C/D.
Q: Can the IC693MDL655E accommodate both sinking and sourcing field devices on the same module?
A: Yes, each of the four isolated 8-point groups can be independently wired for either positive (sinking) or negative (sourcing) logic, provided all 8 points within a single group share the same wiring configuration.
Q: Is the IC693MDL655E module hot-swappable during baseplate operation?
A: No, primary system power to the Series 90-30 baseplate and external 24 VDC field supplies must be fully isolated before inserting or removing the module to avoid hardware damage.
Field Installation Guidelines
- Disconnect baseplate supply power and external 24 VDC field voltage prior to seating the module in the chassis.
- Verify proper engagement and lock latching of both 24-pin Fujitsu cable connectors to ensure continuous pin contact under industrial vibration.
- Route low-voltage sensor cables away from high-voltage AC motor wires and variable frequency drive output conduits to prevent inductive noise coupling.
- Connect the system enclosure earth ground strap directly to the baseplate mounting frame to preserve 1500 V field-to-logic optical isolation performance.
