8 Channel Isolated Thermocouple

This CAN based 8 Channel Isolated Thermocouple to CAN device measures temperatures from -200°C to +1800°C [1] at a rate of up to 40Hz per channel.

Accuracies:

• ±0.5°C/±1.5°C (typ./max.) from 0 to 85°C and
• ±1°C/±3°C (typ./max.) from -40 to 125°C.

Each channel is isolated to 1000VDC and the unit features open-circuit and short-circuit detection features, indicating when the thermocouple wire is broken, disconnected or if the thermocouple is shorted to ground or power.

The unit ships with K type miniature thermocouple connectors as standard allowing easy connection to standard thermocouples. If required, it is possible to have a different type of miniature thermocouple connector – K, J, T, N, S, E, B and R are supported.

This isolated thermocouple can be DIN rail mounted and has two IP67 JWPF connectors allowing it to be daisy chained with up to 128 additional modules enabling many measurement channels if required. The configurable CAN bus speed and address along with the supplied DBC file allows easy addition into almost any CAN bus. The input supply voltage can range from 9 to 32V.
