- 1771 plug-in interface for Data Highway Plus and Remote I/O
- 850 nm multimode optics with ST connectors
- Interactive diagnostics and self-healing dual-media-ring operation
OCM-DPR-85-D-ST is a Phoenix Digital 1771 Plug-In DH+/Remote I/O Fiber-Optic Communication Module designed for Allen-Bradley Data Highway Plus and Remote I/O networks in a 1771 chassis.
It converts supported Allen-Bradley copper network traffic to a redundant fiber ring while monitoring optical and communication conditions for fault isolation.
Before installation or replacement, decode every suffix and verify protocol, data rate, multimode fiber, ST connectors, ring topology, backplane capacity, and transmit/receive polarity.
Availability, condition, price, and shipping time for OCM-DPR-85-D-ST are confirmed during quotation.
