Ensuring reliable protection communication in critically short timeframes

The TP10 device is designed for the transmission of distance protection commands, binary states, and differential protection signals over optical fiber or via PDH/SDH/Eth networks. It enables the simultaneous transmission of 10 bidirectional commands and a differential protection signal connected via an optical or electrical interface. Group signal transmission is possible over PDH/SDH networks, Eth/IP networks, or directly via optical cable. Transmission reliability can be increased by 1 + 1 transmission path redundancy.

Key features include low input impedance for increased noise immunity, sensitivity threshold settings via voltage and time filtering, galvanically isolated inputs and outputs, 8-bit addressing for secure transmission, continuous monitoring of connection and transmission time, transmission routing for up to 4 directions, transmission time starting from 1 ms, a command log with 1 ms recording accuracy, redundant power supply (48 VDC / 110 VDC / 220 VDC / 230 VAC), 820 nm optical interface for differential protection, C37.94, proprietary interfaces (for older SIEMENS, ABB, SEL types), E1/G.703, Ethernet 100Base-TX, and central or local monitoring (Eth, SNMP).
