1746-OW16 Advantages
The Allen‑Bradley 1746-OW16 SLC 500 Output Module stands out from comparable digital output modules in several key areas.
Dual-voltage dry relay contact design. The Allen‑Bradley 1746-OW16 SLC 500 Output Module uses isolated relay dry contacts, supporting both AC and DC load switching without restricting load voltage type, eliminating the requirement for extra interposing relays for many on-site applications.
Sixteen high-density output channels grouped into two banks. The Allen‑Bradley 1746-OW16 SLC 500 Output Module splits 16 outputs into two independent 8-point groups with separate common terminals, allowing users to assign different voltage supplies to each group flexibly.
Built-in high isolation protection. The Allen‑Bradley 1746-OW16 SLC 500 Output Module provides 1500V isolation between the PLC backplane and field load circuits, isolating surge voltage and load-side fault interference to protect the SLC‑500 CPU and other backplane modules.
Front individual channel status LEDs. The Allen‑Bradley 1746-OW16 SLC 500 Output Module is equipped with dedicated LED indicators for each output channel, enabling technicians to quickly verify output status during commissioning, troubleshooting and routine maintenance.
Native Allen‑Bradley SLC‑500 system integration. As a factory‑original SLC‑500 series component, the Allen‑Bradley 1746-OW16 SLC 500 Output Module can be directly inserted into any standard SLC‑500 chassis slot without conversion adapters or mechanical modification.
Wide industrial environmental adaptability. The Allen‑Bradley 1746-OW16 SLC 500 Output Module is built to withstand workshop vibration and shock, suitable for long-term continuous operation in factory automation environments with mixed AC and DC control loads.
