Allen-Bradley 1771-OAD PLC-5 Analog Output Module

Allen-Bradley 1771-OAD PLC-5 Analog Output Module is a 16-channel AC output card for the PLC-5 1771 I/O system, designed to switch line-voltage loads from a PLC program. Each of the sixteen outputs can drive devices such as relays, contactors, or valve coils, with an operating range of 10 to 138 VAC (the 120 VAC region commonly used in industrial environments), and power is supplied from the 1771 I/O backplane rather than a separate supply. The module is intended for installation in a 1771 I/O chassis and is compatible with standard PLC-5 block transfer and addressing, integrating into the system’s overall I/O addressing scheme. Operating temperature for the unit is specified as 0 to 60 °C, ensuring reliable performance in typical factory environments where PLC-5 equipment is deployed. This 16-channel AC output module provides a compact, rack-mountable solution for centralized control of multiple line-voltage loads from a single PLC-5 rack.
