Allen Bradley 1791-16BC Discrete I/O block

The 1791-16BC is a Discrete I/O block that is manufactured by Allen-Bradley. This module features embedded channels composed of Sixteen (16) 10-30VDC input channels and Sixteen (16) 10-30VDC output channels. This module is a compact device that is capable of functioning as a single Remote I/O chassis. It has embedded power supply, communication interface, input and output channels.

1791 Block I/O systems are primarily designed to be used in Remote I/O applications. This components is compatible with different Allen-Bradley controller platforms such as PLC2, PLC3, PLC5, and SLC 5000 product family. Depending on the controller used, Remote I/O baud rate ranges from 57.6K up to 230.4K baud rate. If used with 57.6 baud rate, maximum Remote I/O that can be used is 10,000 cable-feet; 5000 cable-feet for 115.2K and 2500 cable-feet for 230.4 K.
