Chassis and Hardware

SLC modular chassis provide flexibility in system configuration. Four chassis sizes are available to suit your application needs. Choose from 4-slot, 7-slot, 10-slot, and 13-slot chassis based on your modular hardware component requirements.

The SLC 1746 modular chassis houses the processor or I/O adapter module and the I/O modules. A maximum of 3 chassis can be interconnected with chassis interconnect cables for a maximum of 30 module slots that can be addressed locally by a processor or I/O adapter in the left-most slot of the 3-chassis assembly.
