Phase Detector

Power Grid Voltage Detector

About Power Grid Voltage Detector

Phase detector device is intended to detect presence of mains power voltage on 6 Line wires against 3 Neutral wires (1 Neutral is shared with 2 Lines). Earth wire is not used. Power line side is galvanically isolated from the rest of device. Presence of power voltage is evaluated by means of AC zero crossing events counting and relative time measurement.


This device targets to monitoring and verification testing of power switching devices, such as general-purpose relays, triacs, heating systems etc.

Parameters

Parameter Value
Mounting 35/7,5 DIN
Width 3 modules
Number of Inputs 6
Line Load 2 x 100 kOhm

Functions and Benefits

  • 6 Lines evaluated at the time
  • Count zero-crossing events over time
  • ON and OFF state time measurement
  • Tolerance parameter allows for sparse missing periods and relay debouncing
  • Current state time measurement
  • 1 Digital output Modbus RTU with address switch
  • Remote firmware update over Modbus

Software

Softwar tools are available on Github supporting:

  • Graphical visualization of all registers
  • Read and write register operations
  • Update firmware of the device
