1746-IO4

The Allen Bradley SLC 500 Digital Combination I/O Module 1746-IO4 comes with 2 inputs and 2 outputs. The 1746-IO4 falls into the voltage category of 120 Volts of AC power for inputs, and 100 to 120 Volts of AC power for relay contact outputs. The operating voltage of this module ranges from 85 to 132 Volts AC at 47 to 63 Hertz (inputs). Its minimum output voltage is 5 Volts AC and its maximum 265 Volts, at 47 to 63 Hertz or 5 to 125 Volts DC. The Continuous current of this module is 4 A. At 5 Volts of DC power, this module's backplane current consumption is .030 mA, while 24 Volts of DC will result in a backplane consumption of .025 mA.

While operating, the 1746-IO4 module's temperature can fluctuate between -25 and 60 degrees Celsius (-13 to 140 degrees Fahrenheit). Its nonoperating temperature lies between -40 and 85 degrees Celsius (-40 to 185 degrees Fahrenheit). The relative humidity of this module ranges from 5% to 95% without condensation. The operating vibration displacement of this module peaks at approximately 0.015 inches at 5 to 57 Hertz while its operating shock is 10 g. The terminal on this module has a self-lifting lift plate that receives two 14 AWG (2 millimeter) cables and is equipped with  LED indicators on the front, which can display an input point status. The status indicator lights up when the correct signal to the input terminal is applied. Input power to the SLC 500 module must be routed separately from the cable to the I/O device.
