3-Phase-3-Wire Connection Intelligent Digital Electric Isolation Sensors/Transducers

The CY-AJ31-1/2 and CY-AJ32-1/2 Series (two watt meter method), Intelligent Digital Electric Isolation Sensors/Transducers are suitable for monitoring and diagnosis of three phase AC networks and power lines with three wires connection. The measurands are current, voltage, frequency, power and energy etc. Digital output interface is RS-485 for CY-AJ31-1/CY-AJ32-1 and RS-232C for CY-AJ31-2/CY-AJ32-2. The output format of all products is ASCII. The CY-AJ31-1/2 series is double isolated, while the CY-AJ32-1/2 is treble isolated.

CY-AV31-1/2 and CY-AV32-1/2 (two watt meter method) are designed for voltage measurement, CY-AI31-1/2 and CY-AI32-1/2 (two watt meter method) for current measurement.
