AC 230V mains voltage presence sensor

Sensor in the form of a mains plug. It shows in a simple way whether the mains supply voltage of 230 V is available.
Useful especially in all installations with UPS.
The optical measurement method guarantees galvanic isolation between the 230 V power supply and the information output.

Uses a logical output (INPD terminal, to be connected to the INPD/iD input in tcPDU/LK):

• current 230 V supply - low state 0, approx. 0.1 V
• no 230 V supply - high state 1, 2 V

This dependency can be easily used to configure notifications in the Events tab in tcPDU or LK devices.

Technical specifications

• Power consumption: 1 mA / 230 V AC
• Operating voltage: 230 V
• Cable length: 1 m
• Terminals: +5V, GND and INPD

The resistor is soldered to the INPD cable!
