Universally configurable temperature limit value switch with two transistor outputs for the connection of 2, 3,
and 4-conductor resistance thermometers and thermocouples. Configurable via DIP switch or software, screw
connection technology
Product Description
Universally configurable temperature limit value switch with two transistor outputs for the connection of 2, 3, and 4-conductor resistance thermometers
and thermocouples. You can configure the device using one of the free software solutions available or your smartphone. 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.
