Contact resistance monitoring device Selectric SRC

The device is designed for real-time condition monitoring of contact connections in 0.4 kV power circuits. Monitoring is performed based on contact resistance parameters with data transmission to SCADA via the Modbus TCP protocol.
The device is compact and designed for DIN-rail mounting.

Main functions of the device:

1. Condition monitoring of:
   1. busbars and busbar tap-offs;
   2. upper and lower contacts of devices;
   3. pluggable or withdrawable contacts.
2. Data transmission:
   1. via Ethernet and Wi‑Fi;
   2. with hot-standby channel redundancy.
3. Automatic calibration of contact resistance.
4. Input protection against high potential (circuit isolation via relay).
5. Compatibility with SCADA and Industrial Control Systems (ICS).
