MULTI POWER TRANSDUCER
Functions & Features
[3] EXTERNAL INTERFACE
1: Modbus, Do × 1, Di × 1
2: 4 – 20 mA DC × 4
• Measures simultaneously several variables of a heavy-
current power system: current, voltage, active, reactive,
and apparent power, active and reactive energy, power
factor, frequency, etc.
3: 1 – 5 V DC × 4
4: 4 – 20 mA DC × 2, Do × 1, Di × 1
5: 1 – 5 V DC × 2, Do × 1, Di × 1
6: 4 – 20 mA DC × 2, Do × 2
7: 1 – 5 V DC × 2, Do × 2
• All measured values, counter values, setting data are
stored in the non-volatile memory at the power off.
• Conversion factors, system configuration, interval times
are programmable.
• Open collector output for alarm or energy count.
