Overview
The GE Fanuc IC693CHS391M is a 10-slot modular baseplate engineered for the Series 90-30 PLC platform. This expansion plate is designed with a slot at the left end of the baseplate especially for the power supply. This baseplate features 1 CPU slot and 9 I/O slots for a total of 10 slots. The EMI-enhanced design provides robust electrical isolation in industrial environments with high electromagnetic interference.
Key Features
- 10-Slot Configuration: The IC693CHS391M expansion baseplate has been designed and manufactured for installation in the GE Fanuc Series 90-30 PLCs, can be used to extend a PLC so that it can accommodate more I/O modules and field devices, and comes with 10 slots for hosting input and output modules.
- EMI-Enhanced Design: Provides noise immunity and protects against electromagnetic interference in demanding manufacturing and process control environments.
- Modular Architecture: Hosts the local electronic backplane to power the attached modules.
- System Flexibility: Only one CPU baseplate can be installed in a system; other baseplates permitted are expansion or remote I/O baseplate.
- Expansion Port: Has a 25-pin female connector present on the right hand side for connecting expansion and remote baseplates.
- DIP Switch Configuration: Comes with a DIP switch for flexible setup and addressing options.
