Allen-Bradley 1746-OB16 Brand Introduction Allen-Bradley 1746-OB16 is SLC 500 series digital DC output module developed by Rockwell Automation for PLC discrete control. It specializes in sending digital switching signals to solenoid valves, contactors and indicator lights, serving as 16-point sourcing output unit for SLC500 controller rack. Digital Output Module is the core unit of Allen-Bradley 1746-OB16. Digital Output Module adopts single slot chassis mounting structure for 1746 backplane. Digital Output Module supports 16 channels sourcing DC output. Digital Output Module realizes on-off control of field actuators according to PLC logic program. Allen-Bradley 1746-OB16 provides stable Drive for workshop field actuator control. Drive supports 10-50V DC external load power supply. Drive has optical isolation between backplane and field side. Drive features status LED indicators for each channel to simplify fault inspection. Allen-Bradley 1746-OB16 features reliable Transmission for SLC500 PLC and field devices. Transmission communicates via 1746 chassis backplane bus. Transmission is fully compatible with SLC500 CPU and SLC expansion racks. Transmission delivers fast digital control signals to field-side loads. Allen-Bradley 1746-OB16 is widely used in packaging machinery, material handling equipment and legacy SLC500 automation system renovation. With mature Rockwell SLC500 I/O technology, this output module works within temperature range 0~60℃ and has strong anti-vibration and anti-interference performance. It provides full lifecycle technical support including wiring, commissioning and after-sales maintenance, serving global users as a trusted 16-point DC sourcing output module solution.
