Product Details

1791-16BC is an AB Discrete I/O Block. The Block I/O product line is comprised of remote I/O devices with self-contained power supply, programmable controller interface, input/output connections and signal conditioning circuitry. 1791-16BC is a 16 input/16 output block I/O module with 24 Volts DC. These Block I/Os are compatible with PLC-2, PLC-3, PLC-5/250 and PLC-5 family programmable controllers, and the SLC 5/02 modular controllers. To protect the module, the 1791-16BC block I/O module is internally fused so there no external power fusing is required. The outputs of the block I/O modules are not fused. It is recommended to fuse the outputs of 1791-16BC. External fusing must be provided by operators if fusing is desired.

1791-16BC has horizontal and vertical mounting options; each of which has its own output current rating. At 60 degrees Celsius, vertical mounting has a current rating of 500 milliamps while horizontal mounting has a 250 milliamps current rating. Low temperatures will increase the current rating. The current rating of vertical mounting will increase to 1 Amp at 30 degrees Celsius while horizontal mounting at 30 degrees Celsius will increase the current to 500 milliamps. The maximum surge current for the1791-16BC is 3 Amps for 50 milliseconds. Please be aware of all module specifications before installing or connecting this module with other devices.
