Switchgear Monitoring Module MKKO-18 for 0.4 kV Equipment Control

The product is designed to monitor the state of switching equipment used in 0,4 kV networks (circuit breakers, contactors, etc.). etc.). The product contains the following functional units: interface device with the 0,4 kV network containing the following components 0,4 kV network containing opto-isolated voltage sensors, the basic module containing microcontroller, RS485 interface node and voltage stabilisation unit.

The microcontroller performs data acquisition from the sensors (interface device with the 0.4 kV network). 0,4 kV network) and analyses the state of the contact group connected to the pair of sensors by the voltage difference with respect to the neutral. voltage difference with respect to the neutral.

The microcontroller exchanges data through the RS485 interface node. The voltage stabilisation unit ensures the operation of the product in the range of DC supply voltage 5..15 V..
