TEMPERATURE-INSULATED CONVERTER FOR THERMOCOUPLES

General Description

The K109TC instrument is a 4-point galvanic insulator. It converts a temperature signal
read by a thermocouple into a signal normalised in voltage or current; besides it has a
passive output which commutates at the overcoming of a threshold set through a button on
the front.
The module's main features are its compact size (6.2 mm), attachment to a 35 mm DIN
rail, bus-connector power supply option, quick connection by spring terminals, and easy
configuration in the field by DIP-switch.
