Picture of AFR1 Control Relay
AFR1 relays are used to detect the presence of liquid at levels of mounted contactron sensors. It allows for maintaining minimum and maximum states of the controlled liquid within the range set by the user. It includes an 8 VAC control voltage source for float sensors. The relay works with liquid level, flow sensors which are included in our offer. The set includes a relay socket with DIN rail mounting.

Maintaining the level of liquid in the tank - when the liquid level drops to the MIN state (i.e. the MIN sensor is open) the auxiliary contact will be switched to position 6 and the pump will be activated. When the MAX state is reached (i.e. the MAX sensor is closed) the relay contact switches to position 5 and the supply pump is switched off. The device maintains the liquid state between the MIN and MAX sensors by switching the state of the auxiliary contact between 5 and 6 (turning the pump on and off).
Example of use - maintaining the level of liquid in the tank.
The video shows the operation of the HT liquid level sensors and their practical application. All with the help of the AFR1 relay adapted to them.
AFR1 Relay - Application with two sensors mounted at any level.
AFR1 Relay - Application with a two-float sensor.
AFR1 Relay - Application with a single float sensor.
AFR1 Relay - application with flow sensor.
