The SM20 is a versatile level control or

interface module that can also be used in

many other process control applications.

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.

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.
