Short circuit monitoring
Pumps are monitored with PTC resistors or thermal contacts. When PTC resistors are used, the sensor cable should be monitored for short circuits. The available power supply is 24 V DC. The sensor circuit must be galvanically isolated from the power supply.
The G2TFK02 24-240VAC/DC can be used for both purposes (PTC or thermal contact) depending on how it is connected. Thanks to the integrated CoolZoom power supply unit, it is suitable for a wide voltage range and ensures galvanic isolation between the sensor circuit and the power supply.
