Thank you very much for buying a TB 45 temperature monitor.

TB 45 temperature monitor are used for process monitoring. The units provide process value measurement, limit sig

nalling and switch-off. Possible applications are heating and cooling processes. Configuration as an electronic temper

ature monitor or as a limit signaller is possible.

A TB 45 offers min. one universal input, one limit contact and one pre-alarm contact. Optionally, the unit can be

equipped with one universal output and a second universal input.

Galvanic isolation of inputs and outputs, supply voltage and communication interfaces is provided.

Applications

TB 45 can be used as a

–

certified temperature monitor to DIN 3440 / EN 14597

–

or as a limit signaller for various process signals.

TB 45 as a DIN-certified temperature monitor (type2) can be used in systems in which exceeding of a defined tempera

ture causes damage.
