230V AC voltage presence sensor

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

Uses the INPD as input:
- 230V power supply present - low state 0, approx. 0.1V
- no 230V power supply - high state 1,  2V
This relationship can be easily set for notifications in the Events tab of tcPDU or LK devices.

Technical specifications:

• power consumption:             1mA /AC 230V
  - operating voltage:                 230V
  - cable length:                         1m
  - terminals:                               +5V, GND and INPD

Resitor is soldered to INPD cable.
