GE IC693CPU331S Series 90-30 CPU Module

Configured for central processing and ladder logic execution in Series 90-30 PLC systems, the GE IC693CPU331S (IC693CPU331 Single Slot CPU Module) provides direct physical/electrical execution.

Hardware Specifications

Deterministic Backplane & Processing Attributes

The IC693CPU331S processes control algorithms at a clock speed of 10 MHz to maintain fast instruction cycle times across Series 90-30 backplane racks. High-density system interaction is governed by the 16 KB user program memory, which stores configuration logic, registers, and ladder programs while preserving backplane bus communication velocity. Full firmware flash compatibility allows synchronous data exchanges between the CPU, power supply, and local I/O modules during high-speed execution loops.

Frequently Asked Questions

Q: What rack slot position is required for installing the IC693CPU331S CPU module?

A: The IC693CPU331S must be installed in Slot 1 of the main Series 90-30 CPU baseplate, immediately adjacent to the system power supply module.

Q: How is program logic stored and preserved on the IC693CPU331S module?

A: User logic is stored within 16 KB of onboard memory, supported by the baseplate memory backup battery to preserve ladder programs during main power shutdowns.

Q: Can the IC693CPU331S CPU module be removed or replaced while baseplate power is turned on?

A: No. Primary power to the Series 90-30 rack must be completely disconnected before removing or inserting the CPU module to protect sensitive backplane components.

Field Installation Guidelines

1. Isolate all main power sources feeding the Series 90-30 baseplate prior to inserting or removing the IC693CPU331S module.
2. Align the rear edge connector with Slot 1 on the CPU baseplate and push firmly until the upper and lower housing latches lock into position.
3. Verify that the baseplate lithium battery is connected before loading configuration memory to prevent program loss on power removal.
4. Keep serial communication cables routed away from heavy motor leads and high-voltage line conductors to suppress electromagnetic interference.
5. Torque all panel chassis mounting bolts to establish low-impedance grounding paths between the baseplate frame and the enclosure backpanel.
