Allen-Bradley Rockwell Automation 1791-24BR block I/O module

The Allen-Bradley 1791-24BR is a block I/O module. This relay output module can support 24 input modules, with 3 groups of 8 inputs. Its on-state voltage range is from 10-30 Volts DC and off-state voltage is a maximum of 5 Volts DC. The on-state current is a minimum of 2.5 milliamps at 10 Volts DC and a maximum of 11 milliamps at 30 Volts DC and off-state current is a minimum of 1.5 Amps. The external power of this module is 19.2-30 Volts DC for the voltage and 300 milliamps for the current. The maximum power dissipation is 14.5 Watts and the maximum thermal dissipation is 49.4 BTU/hour. It 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 module has an operating temperature of 0-60 degrees Celsius, a storage temperature of 40-85 degrees Celsius, and a non-condensing relative humidity of 5-95%.
