GE MiCOM Agile P591 fibre-optic-to-electrical communications interface unit, model P591601A0M0000B. This is an interface unit, not a complete differential-protection relay.Data-rate check: The source-specific configuration records 64 kbps, while a general feature line also mentions 2 Mbit/s. Confirm this unit's supported rate and relay/network compatibility; 2 Mbit/s operation is not established.Original source technical and configuration informationThe MiCOM P591, P592 and P593 are stand-alone fiber optic to electrical communications interface units. They can be used with the MiCOM P54x and P521 current differential relays or other MiCOM protection relays that support InterMiCOM64 communications. The P591, P592 and P593 interface units allow the relays to be connected to remote multiplexing equipment or other communication network equipment. The MiCOM P591conforms to the ITU-T G.703 co-directional interface at up to 64 kbit/s. • P591 – Fiber optic to electrical signal G.703 (co-directional) 64 Kbit/s or 2Mbit/s P591601A0M0000B G.703 Interface 19.5 - 300 Vdc Inom = Not Applicable 64 kbps Product Specific = NONE Protocol Options = Not Applicable Flush Rack / Panel Multilingual (Internationally Recognised Symbols) Software Standard - (Not Applicable) Setting Files Standard - (Not Applicable) Hardware Suffix: B
