Product Overview
The 1791-16BC is a 24 V DC discrete Block I/O module in the Allen-Bradley 1791 Block I/O family. It integrates 16 inputs and 16 outputs along with power supply, Remote I/O (RIO) interface, signal conditioning, and status indicators in one compact housing. This module is used in distributed I/O architectures with controllers such as PLC-2, PLC-3, PLC-5, and SLC-500, typically deployed on machine perimeters or plant-floor remote racks to connect field devices to controllers via DH-485 or RIO links. Part number 1791-16BC is included twice.
Best Suited For
- Remote I/O architectures with PLC-2/3/5 or SLC-500
- Field-mounted block I/O distribution
- Distributed control installations requiring both inputs and outputs
