IRIG‑B Interface Options for P7 Relay Using BNC Connection

Issue

Can the IRIG‑B port on a P7 relay interface using a BNC cable, and is any adapter or converter required?

Product

Powerlogic P7 Protection Relay

Environment

Systems using IRIG‑B time synchronization distributed via BNC‑terminated cabling.

Cause

The P7 relay does not have a native BNC IRIG‑B input, leading to the need for an appropriate interface option.

Resolution

Yes, the P7 relay can receive an IRIG‑B signal through a BNC cable by using the IRIG-B time synchronization module, part number REL51045 module, which connects to the P7 relay’s EXT IN port and enables proper IRIG‑B input.

The characteristics of the IRIG-B module are:
