1791R-0B16P

The Allen Bradley 1791R-0B16P is part of the CompactBlock I/O 1791R series. This I/O block has no inputs but 16 outputs, which come in groups of 4 or 8. The 1791R-0B16P has several built-in features, including I/O circuits and a remote I/O adapter, making this module suitable for applications with space limitations. It also cuts costs, because there’s no need to buy an external power supply or adapter for this device. You can install this block with the removable terminations feature, which makes re-wiring unnecessary. The 1791R-0B16P has similar output characteristics to the 1791D series. This module has a range of on-state voltage output between 10 and 30 Volts DC. The maximum on-state current output of this I/O block is 0.5 Amps. For 10 milliseconds, the maximum surge current is 1 Amp. There are three indicators available on this module. These are the status, communications, and I/O indicators. There are also three communication rates for this module. The communications rate depends on the distance. The longer the distance, the lower the communication rate will be. This module has 230.4 Kbps of communication rate when the distance is 762 meters. On the other hand, this module will only have a rate of 57.6 Kbps if the distance is 3048 meters. Before turning this module on, use the DIP switches to set the baud rate.
