1746-0B16 D | Isolated Sourcing DC Output Module

The 1746-OB16 is a DC Output Module from the SLC 500 product family. The 1746-OB16 includes 16 outputs with 24V DC. The 1746-OB16 has 16 points per common and an operating voltage between 10-50V. The backplane current for the output module is 0.280A at 5V DC and 0.0A at 24V DC. On a maximum resistive load, the 1746-OB16 has a signal ON delay of 0.1ms and a signal OFF delay of 1.0ms. In addition, the 1746-OB16 has a maximum off-state leakage current of 1mA.The 1746-OB16 has a maximum ON-state voltage drop of 1.2V at 0.50A and a surge current per point of 3.0A for 10ms. For the 1746-OB16, surge current repeatedly occurs once every 1 second at 30°C (86°F) and twice every 2 seconds at 60°C (140°F). The minimum load current of the module is 1mA. The 1746-OB16 has a continuous current per module of 8.0A at 30°C (86°F) and 4.0A at 60°C (140°F). The continuous current per point is 0.5A at 30°C (86°F) and 0.25A at 60°C (140°F). To avoid a surge current when switching 24V DC inductive loads for transistor outputs, add a 1N4004 diode wired reversely across the load.
