Function

Control relay to monitor the level ofconductiveliquids

The TCL controls the level of conductive liquids in a conductive or non-conductive container and works by passing a low voltage through the liquid from suitable probes to an earth return which can either be the container or another probe.

Single point sensing:

The relays R1, R2 and R3 change over each time the liquid contacts C and S1, C and S2 or C and S3. DIP-switch Function R3 inverts relay 3.

Two point sensing:

The relay changes over each time the liquid contactsC,S1 and S2. The relay resets when the liquid level returns below S1.

R2... filling

S3 can be used to monitor limits.

Note: Do not make a connection between A2 and C when using TCL without galvanic isolation. (DC supply versions) DC-DC isolation on request
