Allen-Bradley 1771-OBD is a 16-point digital DC output module for PLC-5 systems, delivering 16 sourcing outputs in a single-slot module that operates from 10 to 60 V DC. Each output can source up to 2 A, with a maximum of 8 A total per module, and it is designed to handle a 4 A surge per output for 10 ms. The module draws about 400 mA from the PLC-5 backplane at 5 V and is typically wired to field devices using the 1771-WH wiring arm. This 16-point DC output module is part of the PLC-5 I/O family and was discontinued on January 31, 2021.
