Rockwell Automation’s 1771-OMD/B module is a 16-channel digital AC output module in the Allen-Bradley PLC-5 series with a 220 volt AC voltage class. The module draws power from the rack power supply of the PLC 5 controller system through its backplane and requires 700 mah of current to operate. The 1771-OMD/B module is designed to directly drive terminals on the PLC 5 series AC/DC input modules and is an important part of achieving precise control in industrial automation systems.
