How to Wire an Isolated AC Voltage Sensor?

The following wiring diagram shows how to connect the SUCH isolated AC voltage sensor to the input signal, output device, and auxiliary power supply. Ensure all connections are made with the power off before installation.

1. Input Connection

Connect the AC voltage input terminals to the measured line (0–1000V AC). Ensure the input wiring is rated for the maximum voltage of the application.

2. Auxiliary Power Supply

Connect the auxiliary power supply to the designated terminals. This isolated AC voltage sensor supports DC24V or AC/DC220V power input (user-specifiable). Verify the supply voltage before powering on.

3. Output Connection

Connect the output terminals to the receiving device (PLC, controller, or data acquisition system). Select the appropriate output signal range (0–5V or 0–10V DC) based on the input specifications of the connected device.

4. Load Capacity

The voltage output supports a maximum load current of 5mA. Do not exceed this rating to avoid signal distortion or device damage.
