The SM20 is a versatile level control or
interface module that can also be used in
many other process control applications.
One level switch can be connected for an
alarm or two level switches to start and
stop a submersible pump or a solenoid
valve for emptying/filling function

It works with all kind of level switches,
including conductive probes, as well as
pressure switches or other limit switches.
The module can be used as a dry-running
protection, with a pressure switch or filling
level control switch, to start and stop a
pump.
Power supply 240/415 Vac.
Two out-puts:
Main output SPCO 20(8) Ampere 250V
Secondary output SPCO 10(4) Ampere 250V
automatic/manual switch
LED indicators for:
power supply, low level and output on.
Other versions can be made for particular applications. Please contact Cynergy3 with your requirements.

Low voltage input 19-20 for pressure switch
with contacts closed at minimum pressure
or level switch with contacts closed when
level low. NB These terminals must be
bridged if no sensor is connected.
