Universally configurable temperature limit value switch with N/O relay output for the connection of 2, 3, and
4-conductor resistance thermometers and thermocouples. Configurable via DIP switch or software, screw
connection technology
The figure shows a version with
push-in connection
Product Description
Universally configurable temperature limit value switch with relay output and plug-in connection technology for switching temperature limit values. 2-, 3-,
4-conductor RTD and TC sensors can be processed on the input side. A relay with N/O contact is available on the output side. This makes it possible to
switch loads up to 250 V AC/DC and max. 6 A. You can configure the device using one of the free software solutions. Default settings can also be made
directly on the device by simply using the DIP switches (see configuration table). The temperature limit value switch supports fault monitoring and NFC
communication.
