The threshold switch is used for controlling units, pumps, fans, burners, etc. Once the input voltage reaches the switching threshold, the relay activates. If the input voltage falls below the cut-off threshold, the relay deactivates. The module is designed for a two-stage control via an analog 0 to 10 V DC control signal. Connection with screw terminals, control signal 0 V DC = no stage active (OFF), control signal 5 V DC = stage 1 active, control signal 10 V DC = stage 1 and stage 2 active, with manual control level.
