- Sixteen DC inputs and sixteen sourcing DC outputs
- Communicates on the Universal Remote I/O link
- Field-mounted block form factor with grouped isolation
1791-16BC concentrates a full set of discrete input and output points near the machine while returning their image through Remote I/O.
Two groups of eight provide structured power and return connections, and the output loading changes with mounting direction and temperature.
The block therefore has to be replaced as a wired and addressed network station, not merely as a point-count-equivalent I/O device.
Availability, condition, price, and shipping time for 1791-16BC are confirmed during quotation.
