MiCOM Alstom P591, P592 and P593 units are standalone fibre optic to electrical communications interface units.
Used alongside the P54x current differential relays and other relays with InterMiCOM64 interface, MiCOM Alstom P591, P592 and P593 units securely connect to remote pulse code modulation multiplexing equipment. The internal modem used in the interfacing device ensures fast operation of the differential protection.
Sophisticated connection and synchronisation functions
This range of MiCOM standalone units enables the P54x current differential relays and relays with InterMiCOM64 to be connected to remote pulse code modulation (PCM) multiplexing equipment.
