3-Phase Voltage Transducer Application

Product Application Notes
The ENVIROMUX 3-Phase Voltage Transducer monitors and reports voltage of any 3 phase circuit. Connect the 4-20mA output lead to the ENVIROMUX-S420MA 4-20mA Sensor Converter with the ISA Type 2 connection method. Two ENVIROMUX-S420MA Sensor Converters are required for three-phase monitoring. Note: A spare group will be free on the second Sensor Converter, this group can be used to connect an additional sensor. ISA Type 2 Connection per phase: Connect one end of the colored wire to the terminal marked "2" on the Voltage Transducer. Connect the other end of the colored wire from the Voltage Transducer to the Negative (-) terminal of either group 1 or group 2 of the terminal block on the Sensor Converter. Connect one end of the black wire to the terminal marked "1" on the Voltage Transducer. Connect the other end of the black wire to the Earth Ground terminal in the same group of the terminal block on the Sensor Converter. Connect one end of a short wire to the Positive (+) terminal, and connect the other end of the wire to the 18V terminal on the Sensor Converter.
