Allen-Bradley 1747-OW16 16-Point Output Module

Allen-Bradley 1747-OW16 is a 16-point output module designed for the SLC 500 PLC family. It provides 16 relay-type outputs, organized in two 8-point banks, enabling the PLC to switch external devices such as lights, actuators, and other loads from a single module in an SLC 500 rack. The module is powered through the backplane of a compatible 1747 I/O chassis and communicates with the controller via the standard SLC backplane interface, allowing straightforward diagnostics and status indication for each channel. As part of Allen-Bradley’s SLC 500 I/O family, the 1747-OW16 integrates with the broader Rockwell Automation ecosystem and supports common programming and wiring practices used in discrete-control applications. Its compact, slot-based form factor makes expansion or replacement within an existing SLC 500 system simple, helping designers scale their automation tasks without reconfiguring the controller or wiring scheme. Suitable for retrofits or new installations that require discrete, channelized switching, the 1747-OW16 delivers 16 individually controllable outputs in a single module, consolidating control of multiple devices while preserving panel space and simplifying maintenance.
