The 1771-OBD has an output channel rating of 2 A, resistive, no more than 8 A per module, and no more than 0.2 A per pilot load output.

When the minimum load current of the module is 2.5 mA, the minimum surge current rating for each channel is 4 A per output for 10 ms, repeatable for 2 s per output, and A maximum of 25 A per 10 ms output. The 1771-OBD has an on-state voltage drop to 1.5V dc; The leakage current of the maximum shutdown state is 0.5mA;

The output signal delay is 0.1ms (on-off conversion) and 0.2ms (on-off conversion). It is installed on any of the 1771-A1B to 1771-A4B I/O chassis, except the 1771-A4 I/O chassis.

It is suitable for the 1771-WH, 1771-WHF and 1771-WHFB field wiring arms with a tightening force requirement of 1.0 Nm (9 lb in) and module keying between 10 and 12/22 and 24. The appropriate signal line range for terminating the output device to each module channel is 0.34-2.5 mm2 (22... 14 AWG) Solid or stranded copper wire with an insulation class of 120°C (248°F) or higher and a maximum insulation thickness of 1.2 mm (3/64 inch). It has a maximum surge current of 4 amps per output for 10 milliseconds, repeating every 2 seconds.
