Control modes
The OUTPUT switch is used to select if the relay output is to be activated on rising (POS) or falling (NEG) input signal. In the POS position the relay will be activated when the input signal exceeds the value set by the knob HIGH. The relay will be deactivated when the input signal falls below the value set by the knob LOW. With the switch set to NEG the relay will be activated when the input signal falls below LOW and deactivated again when the signal goes above HIGH.
In both cases the set value for HIGH must always be higher than that set for LOW.
Indication
SC1/D has LEDs which indicate that power is on and that relay is activated.
Application
The signal converter is for example used to control cooling or heating on/off from an analogue 0...10V signal.
