GE IC610CPU101C PLC Module

This central processing unit executes ladder logic programs for the Series One PLC system. It scans inputs, solves logic, and updates outputs continuously. You will install this module in the first slot of the base rack.

Key Technical Specifications

The IC610CPU101C uses an 8-bit microprocessor running at 4.9152 MHz. Its onboard memory stores up to 1.7K words of user program logic. The module also includes a lithium battery for program retention during power loss.

Hardware Architecture and Memory Retention

The IC610CPU101C contains twenty-eight integrated circuits for logic execution. A 3.6V lithium battery maintains program memory for up to two years. Forty-two resistors and thirty-six capacitors filter power and signal lines. The CPU also includes 470 µF of capacitance for brief power hold-up.

Interface and Connectivity

One 24-pin backplane connector links the CPU to I/O modules. One 20-pin programming port accepts the handheld programmer or PC cable. Three front LED indicators show power, run, and battery status. A jumper on the board selects run or program mode at startup.

Practical Installation Notes

Install this CPU only in the first slot of a Series One rack. The IC610CPU101C requires a compatible base with sufficient power supply capacity. Always replace the lithium battery with the PLC powered on. Verify program backup before removing the battery for replacement.
