Tr-7576 Transformer Protection Relay

Salient Features of TR-7576 Transformer Protection Relay :
Six channel AuC based winding temperature scanner.
Designed for monitoring six critical temperature parameters on the transformer, like three windings and core or 6 winding points (either 3 from primary and 3 from secondary or 3 from top and 3 from bottom of the three phase windings).
Designed for high ambient temperature up to 70 A C.
Four potential free NO contacts for Fan control, High Temperature Alarm, Trip & to warn against open or wrong sensor connections.
Fully user programmable with self-test facility
Auto fan exerciser control.
Options of different auxiliary supply voltages.
TR-7576-C, a variant model is available with Isolated RS-485 interface with Modbus RTU protocol in lieu of 4-20mA signal.
