The 1791-16BC is a Discrete I/O block that is manufactured by PLC. 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 PLC 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.
Connect the Block I/O module in daisy-chain topology. This module is always functioning as a Remote I/O adapter. This adapter mode requires a RIO scanner to exchange data with. This module may be installed near the main controller or strategically installed in the plant floor. The 1791-16BC requires an enclosure to protect the device form harmful contaminants and element present in an industrial environment. These includes dust, dirt, grease, oil, water, chemicals and other elements. The enclosure must adhere to the requirements based in the installation area’s classification. The 1791-16BC block I/O has physical dimensions of 6.95H X 4.35W X 3.85D inches. The device has installation clearance requirement of 2 inches on all sides of the module.
