The VCL-6045, Quad (4x) IEEE C37.94 to E1 Converter is a ruggedized and robust, sub-station-hardened protocol converter that converts up to 4 x IEEE C37.94 interfaces to 4 x E1 interfaces. VCL-6045 supports point-to-point and point-to-multipoint applications for Differential and Distance Teleprotection.

The most common application for the VCL-6045 converter is for transmitting IEEE C37.94 data over an E1 network between sub-stations. By installing a VCL-6045 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.

VCL-6045 meets and complies with the IEC-61850-3, EMI, EMC, Surge and Temperature specifications making it suitable for sub-station installations to provide uninterrupted service even in the most demanding and harsh environments.

VCL-6045 is available in 1U high, standard 19-inch rack mount version.

VCL-6045 can be used in point-to-point mode , or Point-Multi-point with VCL-2709:
