The Allen Bradley 1746-OV16 is an SLC 500 general purpose current sinking digital output module. The ladder logic programming on the 1746-OV16 can directly access the output values. It has 16 output points that equate to 16 points per common; it operates at 10 to 50 Volts DC and the backplane current load is 270 mA at 5 Volts DC. The maximum signal delay during the off-state is 1 millisecond, while it is around 0.1 milliseconds during on-state. The continuous current per point is 0.5 Amps at 30 degrees Celsius and 0.25 Amps at 60 degrees Celsius. The maximum surge current per point is 1 Amp for 10 milliseconds. The 1746-OV16 has 0.388 Watts per point and a 1.4 Watt minimum for thermal dissipation and 7.60 Watts in total. It is compatible with a1492 CABLE E. And has a removable terminal block that is compatible with the 1492-CABLE RTBB which has a #18 AWG conductor size and a blue color code. The removable terminal block allows the user to easily access the wiring and make changes to it.

Prior to installing this module, refer to the manual to see the 1746-OV16 module’s wiring diagrams. Be sure to power the device off before attempting to install it, remove it, or make changes to its wiring. The 1746-OV16 is designed to use minimal space, while still offering extensive capabilities and robust performance. It is industrially hardened and remains functional at operating temperatures ranging from 0 to 60 degrees. It can also withstand heavy vibration and relatively 0 to 95 percent non-condensing humidity.
