VCL-MX-1554-RAC, Quad IEEE C37.94 to E1 Converter

Get Data Sheet

The VCL-MX-1554-RAC, Quad (x4) IEEE C37.94 to E1 Converter is a ruggedized and robust, ub-station-hardened protocol converter that converts up to 4 x IEEE C37.94 interfaces to 4 x E1 interfaces. VCL-MX-1554-RAC supports point-to-point and point-to-multipoint applications for Differential and Distance Teleprotection. The most common application for the VCL-MX-1554-RAC converter is for transmitting IEEE C37.94 data over an E1 network between sub-stations. By installing a VCL-MX-1554-RAC converter, the existing IEEE C37.94 interfaces from differential protection relays can be transmitted over the E1 network without incurring large capex or without the tiresome task of having to replace or rewire the IEEE C37.94 relays which need to be interconnected to the far end substations over E1 (SDH) transmission links.
