France SOCOMEC (SOCOMEC) DIRIS series processor control electronic protection relay is set measurement, display, monitor, communication in the integration of integrated automation device, used for electrical equipment for measurement, protection and monitoring of all kinds of electric parameters, the safe operation of electrical equipment.

　　DIRIS series microprocessor controlled electronic protection relay have phase fault and grounding fault protection, can control all kinds of circuit breaker, switch, contactor, etc., and is suitable for low voltage power grid.

　　The characteristics of the DIRIS instrument:

　　Protection function: comply with ANSI CODES 50, 50 N, N, 51, 67, 68 (American national standards)

　　Over current protection: interphase and grounding current

　　And quick break protection: alternate with grounding short circuit

　　Phase failure or imbalance protection (DIRIS CPS, DIRIS CP, DIRIS CPX)

　　Direction of maximum current protection (DIRIS CPS, DIRIS CP, DIRIS CPX)

　　Logical interval (DIRIS CPS, DIRIS CP)

　　Second, according to the different electrical equipment set different protection parameters

　　Three, measurement of U, I, I/o, P, Q, S, F, PF, Imax and Pmax

　　Four, electric metering (active, reactive)

　　Five, U, I, P, F and PF monitoring alarm (DIRIS CPS, DIRIS CP)

　　Six, switch input and output (DIRIS CPS, DIRIS CP)

　　Seven, RS485 interface and the JBUS/MODBUS protocol
