The 1746-OB16 module provides 16 digital output channels, which can be used to control various devices such as motors, solenoids, lights, and valves. Each output channel can be individually controlled and is capable of sinking or sourcing current.

The module operates on a 24V DC power supply and can handle a maximum output current of 500 mA per channel. It has a backplane current load of 140 mA at 5V DC and 0 mA at 24V DC. The module uses a removable terminal block for wiring connections, and the status of each output channel can be monitored through indicator LEDs.

To use the 1746-OB16 module, you would typically integrate it into an Allen-Bradley SLC 500 PLC system by connecting it to the PLC rack and configuring it within the PLC programming software. You can then program the PLC to control the digital outputs based on your automation requirements.
