The Allen-Bradley 1791R-16B0 is a self-contained CompactBlock I/O. The inputs per block of this module can be 4 or 8. This module has its own adapter and power supply. There are 16 inputs and zero outputs on this module. This remote I/O module is compatible with PLC, SLC or SoftLogix programmable controllers. There are a lot of benefits from the features of this module such as NEMA type 3 inputs, DIP switches set rack address, and hardware watchdog functions. You can choose from a broad range of sensors due to the NEMA type 3 inputs feature. You can also reduce commissioning time by using DIP switches set rack address. Hardware watchdog function alerts you to damages to the microprocessor. The input characteristics of 1791R-16B0 are quite similar to the 1791D series. This module has 16 sinking inputs, so the current will flow from input to output. The maximum off-state voltage input of this module is 5 Volts DC. The minimum off-state current input of this module is 1.5 milliamps. Be sure to deliver power that has a higher current than 1.5 milliamps. The range of on-state current input of this module is between 2 to 11 milliamps. The range of on-state voltage input of this module can be varied dependant on the temperature. At 40 degrees Celsius, the range can be 10 to 30 Volts DC. At 60 degrees Celsius, the range can be 10 to 25 Volts DC only.
