The Allen-Bradley 1771-OBD PLC-5 DC Output Module must be used with a series B 1771 I/O chassis. No other output module or single card block transfer module should be placed in the same module group when using 2-slot addressing. The module can be used to directly drive terminals on modules such as the 1771-IB, -IC, -IBD, -ICD. The same DC supply should be used to power both modules, to ensure that ground is at the same potential. 

The module includes one green module active indicator, 16 red status indicators, and one red fuse-blown indicator. The green module active indicator lights when the module is powered, the processor keyswitch is on "run," and the opto-isolators and data paths are functioning properly. It turns off if a fault occurs in the data paths or the opto-isolators. The module will then reset its outputs or set them to last state. The red status indicators provide for system logic side indication of individual outputs. The fuse-blown indicator turns on when the fuse is blown.
