TheIC693CHS392is a 10-Slot Expansion Baseplate for the GE Fanuc (now Emerson) Series 90-30 PLC system.This baseplate allows for the expansion of I/O capacity beyond the local CPU rack.Unlike a "Main" baseplate, the Expansion baseplate does not have a slot for a CPU module; instead, it uses a specialized expansion cable to connect back to the CPU's local logic.
Specifications
Part Number:IC693CHS392
Series:Series 90-30 PLC
Slot Capacity:10 slots total (for I/O modules and Power Supplies).
Module Compatibility:Supports all Series 90-30 I/O and Option modules.
Power Supply Slot:1 dedicated slot at the far left for a 90-30 Power Supply (e.g., IC693PWR321/330).
Bus Connection:Requires a 25-pin D-type "Expansion Bus" cable (IC693CBL3xx series).
Maximum Distance:Can be located up to 15 meters (50 feet) from the CPU baseplate.
Dimensions:43.1 cm x 13.0 cm x 3.6 cm (16.98" x 5.12" x 1.42").
Mounting:Back panel or DIN rail mount.
Features
High-Density Expansion:Provides 10 additional slots to accommodate a wide variety of discrete, analog, and specialty modules.
Expansion Bus Architecture:Features a built-in expansion port at the right end of the baseplate to daisy-chain multiple expansion racks (up to 7 expansion racks per system).
Passive Backplane:Designed for high reliability with no active electronic components on the PCB that could fail under thermal stress.
Mechanical Rigidity:Built with an industrial-grade metal frame to ensure secure module seating and vibration resistance.
Easy Addressing:Modules are addressed based on their physical slot location and the expansion rack ID set via the expansion cable/terminator.
