13-Slot Modular Rack | Series B | New Factory Sealed
The Allen-Bradley 1746-A13 Series B is a high-capacity 13-slot PLC chassis designed for SLC 500 automation systems. It provides a stable mechanical and electrical platform for installing power supplies, processors, and I/O modules, enabling flexible system expansion for medium to large industrial control applications.
This chassis ensures secure backplane communication between modules, supporting fast data exchange, high reliability, and long-term continuous operation in harsh factory environments.
Key features of Allen-Bradley 1746-A13 13-slot chassis:
●13 backplane slots for SLC 5oo I/O modules (various analog, digital, and specialty modules are available).
●Back-panel mounted design for installation within a control cabinet.
●Supports communication with the SLC 50o CPU (Central Processing Unit) through the chassis backplane.
