The 1746-OB16 is an SLC 500 DC Output Module, produced by Allen-Bradley. This output module is capable of communicating with various products found within the SLC 500 product line. This module is equipped with 16 (sixteen) output channels and provides signal voltages of twenty-four (24) volts direct current, or DC. The Allen-Bradley 1746-OB16 is primarily used to control, either manually or automatically, different controls or processes of various industrial machines. The output voltage range of this device is between ten (10) and fifty (50) volts direct current, or DC. The Allen-Bradley 1746-OB16 has a couple of different backplane current consumption stats. At five (5) volts DC, the backplane current consumption of this device is 0.280 amperes. At twenty-four (24) volts direct current (DC), however, the backplane current consumption is 0.0 amperes. The maximum Off-state leakage of this product is one (1) mA and the minimum load current is also one (1) mA.  
The continuous current per point of the Allen-Bradley 1746-OB16 is 0.50 amperes at thirty degrees Celsius (30 °C), or 86 °F, and 0.25 amperes at sixty (60) °C, or 140 ºF. The continuous current per module maximum is 8.0 amps at 30 °C (86 °F) and 4.0 amps at 60 °C (140 °F). The max On-state voltage drop for this output module is 1.2 volts at 0.50 amps. Additionally, the surge current per point for the Allen-Bradley 1746-OB16 is 3.0 amps for 10 milliseconds. The temperature range recommended for the operation of this output module should remain within a range of zero (0) to sixty (60) °C, or thirty-two (32) to one hundred and forty (140) °F. Additionally, a non-operating temperature for this device should stay within a range of -40 and 85 °C (-40 to 185 °F). The operating humidity of the Allen-Bradley 1746-OB16 is between 5% and 95% non-condensing. The isolation of this output module is 1500 volts.
