About 1791-32A0

The Allen-Bradley 1791-32A0 is a block I/O module. Block I/O modules are stand-alone I/O stations that is equipped with fixed I/O channels and a communication interface that support Remote I/O (RIO) communication. The 1791-32A0 in particular is a Thirty-Two (32) channel block I/O module with each channel operating at a nominal input voltage of 120VAC and operating voltage range of 79-132VAC along a frequency of 47-63Hz.

The input channels of the 1791-32A0 are grouped into Four (4) groups with each group having Eight (8) channels each. Each input channel has a maximum Off-state voltage of 35V, minimum On-state current of 5 mA at 79V, 60 Hz and maximum On-state current of 12.3 mA @ 132VAC, 60 Hz. Each channels has switching delays of 1.0 ms for Off to On transition and maximum of 26 ms for On to Off transition.

The 1791-32A0 comes with a single Remote I/O (RIO) communication port with isolation rating of 1250 VAC for I/O group to group isolation and 1250 VAC I/O group to logic isolation. Additionally, the Power supply to RIO port isolation is 500 VAC.

The 1771-32A0 has a maximum power dissipation of 13.62 Watts and maximum Thermal dissipation of 46.44 BTU/hr. When establishing connections to the module, appropriate wire size to use is a 14 gauge stranded wire with maximum insulation thickness of 3/64.

The 1771-32A0’s operating temperature is 0-60 Deg, Celsius while the storage temperature of -40- 85 Deg. Celsius and relative humidity of 5-95%, non-condensing. The module’s input power requirement is 85-132VAC, 47-63 Hz and current of 150 mA.

This module's on-state voltage range is from 79-132 Volts AC at 47-63 Hertz and its off-state voltage is a maximum of 35 Volts. On-state current of this module is a minimum of 5 milliamps at 79 Volts and 60 Hertz and a maximum of 12.3 milliamps at 132 Volts and 60 Hertz, while the off-state current is a minimum of 2.3 milliamps at 60 Hertz. The 1791-32A0 module has an input impedance of 15KΩ at 60 Hertz. The external power required for this module is 85-132 Volts AC at 47-63 Hertz for the voltage and 150 milliamps for the current. It has an isolation of 500 Volts AC for the power supply to remote I/O and 1250 Volts AC each for both I/O group-to-group and I/O group-to-logic. It has a maximum thermal dissipation of 46.44 BTU/hour and a maximum power dissipation of 13.62 W. It also comes with an operating temperature of 0-60 degrees Celsius, a non-operating temperature of -40-85 degrees Celsius, and a non-condensing relative humidity of 5-95%. The module has an input signal delay of 1 ms from off-to-on and a maximum of 26 milliseconds from on-to-off, which allows a half-cycle dropout. Block I/O modules, like the 1791-32A0, are remote I/O devices that have their own programmable controller interface, power supply, signal conditioning circuitry, and input/output connections. They are small, self-contained, and compatible with PLC-2, PLC-3, PLC-5/250, and PLC-5 family programmable controllers and SLC 5/02 modular controllers. The 1791-32A0 module has removable terminal strips on its left and right sides for remote I/O, input, output, and power connections. The status indicators of this module allow you to monitor communication and input/output states. The 1791-32A0 module's two switch assemblies let you configure the starting I/O group, last chassis, I/O rack number, last state, and communication rate. It can be connected using a DIN rail or panel mount and it measures 6.95 x 4.35 x 3.85 inches.
