What is PoM or Power over Modbus?

Modbus RTU – how to interconnect Sentera devices
The term ‘PoM’ or ‘Power over Modbus’ means that both Modbus RTU communication and 24 VDC power supply are transmitted via one single UTP (Unshielded Twisted Pair) cable.

Sentera -M series use this technology and can be connected via one simple RJ45 connector. This makes the wiring more efficient and reduces the risk of wrong connections.
