3508_0 CE-VJ03-32MS2-0.5 AC Voltage Sensor 0-250V (60Hz)
This AC Voltage sensor measures line voltage on mains up to 250 Vrms.
Powered by an external 12VDC power supply, the AC Voltage Sensor provides a 0 to 5VDC analog signal that is linearly proportional to the AC voltage measured at the terminal blocks.
The voltage sensor connects to an analog input on Phidgets I/O boards. The formula to translate the SensorValue into Voltage is:
- Measures line voltage on mains up to 250Vrms
- Operates at 50Hz
- 0.5% Accuracy
- Isolation Voltage of 2500VDC
- DIN Rail mountable
- Connects to any device with an Analog Input

In order to use one of these power supplies with this sensor, you must cut the small plug from the end of the power supply and connect the wires directly into the sensor. You can also use a 3031 – Female Pigtail.
Warning: The AC Voltage Sensor needs to be attached in parallel with the line voltage. This requires cutting and using loose ends of high power cables. ALWAYS be sure to turn off the power running through the cables while manipulating and before cutting the cables. When attaching the cables, be sure to follow your country’s wiring code to ensure safe installment of the sensors and to reduce the risk of injury and fire. If you are uncomfortable, consult with a certified electrician.
This sensor connects to an Analog Input on the:
- 1010 - PhidgetInterfaceKit 8/8/8 Mini-Format
- 1011 - PhidgetInterfaceKit 2/2/2
- 1018 - PhidgetInterfaceKit 8/8/8
- 1019 - PhidgetInterfaceKit 8/8/8 w/6 Port Hub
- 1203 – PhidgetTextLCD
You can use the 3002 - Sensor Cable 60cm or the 3004 - Sensor Cable 350cm to connect the AC Voltage Sensor to your Phidget. Just snip off the connector from one end of the sensor cable and connect the white wire to the terminal marked with an 8, and the black wire to the terminal marked with a 6. The red wire is not used. You can also use a 3031 – Female Pigtail.
This is how you connect the 3507 to a Phidget Board that does not have 12V power supply, such as the 1018 or 1203, using a Sensor Cable.
- Connect the Power Supply +12V wire (the wire with the white line) to the voltage sensor terminal 5 (+12V).
- Connect the Power Supply Ground wire and the Analog Sensor Cable Black wire to the voltage sensor terminal 6 (-).
- Connect the sensor cable white wire to the voltage sensor terminal 8 (+).
- Connect the AC main wires to the voltage sensor terminals 1 (IN) and 3 (IN).
For boards that have power input, such as the 1019 or the 1072, if the supplied power is 12V, then the + terminal block on the Phidget Board can be connected to the voltage sensor terminal 5 (+12V), and the G terminal block on the Phidget Board can be connected to the sensor terminal 6 (-).
