Function
SC1/D is a signal converter which converts a 0...10V
signal to a single pole relay changeover output.
When the input signal reaches the preset signal level
the relay output changes.
SC1/D comes in standard casing for DIN-rail mounting
and has all settings accessible on the front.
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.
