1791-32B0 Allen Bradley

The Allen-Bradley 1791-32B0 is a discrete block I/O module. A total of 32 inputs and 0 outputs are available with this input module, with groups of 8 inputs in each group. It has a 24 Volts DC input voltage, a maximum off-state voltage of 5 Volts DC, and an on-state voltage range of 10-30 Volts DC. On-state current is a minimum of 2.5 milliamps at 10 Volts and a maximum of 11 milliamps at 30 Volts and the off-state current is a minimum of 1.5 milliamps. Its maximum input impedance is 3.4K Ω and its external power is 19.2-30 Volts DC for the voltage and 300 milliamps for the current. The entire module measures 6.95 x 4.35 x 3.85 inches. It can be mounted on a DIN rail mount and compatible cables are the Belden 9463 for the remote I/O link and a 14 AWG stranded wire with a 3/64-inch insulation for the input and output wiring. This module has an isolation of 500 Volts AC for the power supply to remote I/O, I/O group-to-group, and I/O group-to-logic. The maximum power dissipation is 16.3 W
