Module connects thermocouples to CAN bus

The model TI8 from Metis Engineering lets you connect up to eight isolated channels.

UK-based Metis Engineering has introduced an eight-channel thermocouple module that digitizes temperature readings and send them to a host over the CAN bus. The Model TI8 provides up to 2500 V isolation for 1 minute and 600 V continuous across channels.

The module measures temperature from -200°C to 1800°C, depending on thermocouple type. It supports:

Thermocouple type	Temperature range
K (standard model)	-200°C to 1250°C
J	0°C to 750°C
T	-250°C to 350°C
N	-150°C to 1300°C
E	-200°C to 900°C
S	0°C to 1450°C
B	0°C to 1700°C
R	0°C to 1450°C

The module has 0.04 °C measurement resolution. Accuracy dépend on the module’s operating temperature: ±0.5°C (typ), ±1.5°C (max from 0°C to 85°C. Outside of that range (-40°C to 125°C), accuracy is ±1°C (typ), ±3°C. Scan rate is up to 40 samples/sec per channel.

Applications include automotive and industrial.
