Temperature Relays TR640IP
monitor up to 6 sensors for up
to 4 limits. Different sensors
can be connected at the same
time, e.g. Pt 100 (RTD) and
PTC-thermistors. Typical appli-
cations are monitoring of motors,
generators or transformers. An
other application is the use as
a 2- or more step-controller with
additional monitoring of over- or
undertemperature or monitoring
of dierences in temperatures of
2 sensors.
Preset programs allow easy
setting e.g. monitoring of trans-
formers with/without monitoring
of temperature of core or with/
without controlling a ventilator.
