Smart monitoring relays
Ordering details

Description
The temperature monitoring relays CM-TCN are able to measure temperatures of solids,
liquids and gaseous media within up to three sensor circuits using different types of sen-
sors, such as PT100, PT1000, PTC or NTC within the same time. Different types of sensors,
e.g. PT100 and PTC sensors, can be monitored simultaneously.
The temperature is obtained by the sensors in the medium, evaluated by the device and
2CDC251004V0020 monitored to determine whether it is within an operating range (range monitoring function)
or has exceeded or fallen below a threshold. Depending on the parametrization, up to three

CM-TCN output relays signalize the changes in the measuring circuits.
