West Control Solutions TB 45 Temperature Limiter - Manual (Page 5)

. 1 General
Thank you very much for buying a TB 45 temperature monitor.
TB 45 temperature limiter are used for process monitoring. The units provide process value measurement, limit signal-
ling and switch-off. Possible applications are heating and cooling processes. Configuration as an electronic tempera-
ture limiter, temperature monitor or as a limit signaller is possible.
A TB 45 offers one universal input, one limit contact and one pre-alarm contact. Optionally, the unit can be equipped
with one universal output
Galvanic isolation of inputs and outputs, supply voltage and communication interfaces is provided.
Applications
TB 45 can be used as a
– certified temperature limiter/monitor to DIN 3440 / EN 14597
– or as a limit signaller for various process signals.
TB 45 as a DIN-certified temperature limiter/monitor (type2) can be used in systems in which exceeding of a defined
temperature causes damage.
