KRS-E08 HR3 : Three-point control for loads (valves, pumps, fans)

The module controls units, pumps, fans, burners via an analog output with thresholds. As soon as the input voltage reaches the switching threshold, the relay is activated.

When the input voltage drops below the switch-off threshold, the relay is released again. The module is designed for two-level control via an analog control signal from 0 to 10 V DC.

Control signal 0 V DC = Level 1 active
Control signal 5 V DC = No level active (OFF)
Control signal 10 V DC = Level 2 active
With possibility of manual control
Connection with screw terminals
