1746-A7 SLC 7 Slots Chassis


A-B 1746-A7 SLC 7 Slots Chassis

The Allen-Bradley 1746 series is a family of modular I/O modules designed for the SLC 500 programmable logic controller (PLC) platform, manufactured by Rockwell Automation. These modules provide the physical interface between the PLC and field devices (sensors, actuators, motors, etc.) in industrial automation systems.
