FAQ

Q1: What is the GE Fanuc IC693CHS391N used for?
The IC693CHS391N is the main CPU baseplate for the GE Fanuc Series 90-30 PLC. It provides the mounting platform, backplane communication, and power distribution required for the power supply, CPU, and I/O modules to operate as a complete PLC system.

Q2: How many modules can the IC693CHS391N accommodate?
The baseplate provides 10 slots, including one dedicated power supply slot, one CPU slot, and nine slots for I/O or specialty modules, offering flexible system configuration.

Q3: Can the IC693CHS391N be expanded?
Yes. The baseplate includes a 25-pin expansion connector that allows additional expansion or remote baseplates to be connected. Depending on the installed CPU model, a system can support up to seven baseplates.
