Control relay AFR1
pic: AFR1 control relay
AFR1 relays are used to detect the presence of liquids at the levels of mounted reed switch probes. It allows to maintain the 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, liquid flow sensors, which are included in our offer. Included is a relay socket with DIN rail mounting.

Wiring diagram
PF083A relay base and wiring diagram
Operation
Tank liquid level control - when the liquid level drops to the MIN state (i.e. MIN sensor opened ), the auxiliary contact is switched to position 6 and the pump starts. When the liquid level reaches the MAX state (i.e. MAX sensor shorted), the relay contact will switch to position 5 and the feed pump will turn off. The device maintains the liquid level between the MIN and MAX sensors by switching the auxiliary contact state between 5 and 6 respectively (turning the pump on and off).
Application example - maintaining the liquid level in the tank.
The video shows a diagram of HT liquid level sensors and their practical application. All using the AFR1 relay adapted to them.
Relay AFR1 - application with two sensors fixed at any level.
AFR1 relay - application with a two-fluid sensor.
AFR1 relay - application with a single float sensor.
AFR1 relay - application with a flow sensor.
