1746-OX8 Advantages
The Allen‑Bradley 1746‑OX8 8‑point isolated relay output module stands out from comparable digital output modules in several key areas.
Fully individual‑point isolated relay‑contact design. The Allen‑Bradley 1746‑OX8 8‑point isolated relay output module provides complete electrical isolation for every single output channel, allowing mixing of different AC and DC voltage loads on the Allen‑Bradley 1746‑OX8 8‑point isolated relay output module without cross‑circuit interference.
Wide mixed‑voltage dry‑contact switching capability. The Allen‑Bradley 1746‑OX8 8‑point isolated relay output module supports both AC and DC load‑voltage ranges from 5‑265V AC and 5‑125V DC, removing requirement for external interposing relays for many multi‑voltage field‑control applications.
High‑strength 1500V isolation protection. The Allen‑Bradley 1746‑OX8 8‑point isolated relay output module implements 1500V isolation between each field‑load channel and the PLC backplane, suppressing surge‑voltage and load‑side‑fault interference to protect SLC‑500 CPU and other backplane modules.
Per‑channel front‑panel status LED indicators. The Allen‑Bradley 1746‑OX8 8‑point isolated relay output module is fitted with dedicated LED status lights for every output point, enabling technicians to rapidly verify output status during commissioning, fault‑troubleshooting and routine maintenance.
Native Allen‑Bradley 1746 SLC‑500 system integration. As a factory‑original Allen‑Bradley 1746 series component, the Allen‑Bradley 1746‑OX8 8‑point isolated relay output module can be directly inserted into any standard SLC‑500 chassis slot without conversion adapters or mechanical modification.
Flexible multi‑voltage cabinet‑layout capability. The Allen‑Bradley 1746‑OX8 8‑point isolated relay output module supports different supply voltages for each output point, which simplifies cabinet‑wiring for machines containing diverse‑voltage actuators and pilot devices.
