ThermoCAN-4 is a compact, robust CAN-bus temperature acquisition module designed for demanding industrial, automotive, and R&D environments.
It enables four thermocouple channels to be measured accurately and transmitted directly onto a CAN network, simplifying wiring, improving noise immunity, and enabling scalable, distributed temperature monitoring.
Isolated CAN Interface
ThermoCAN-4 features a fully isolated CAN bus, protecting the wider system from ground loops, transients, and electrical noise. This isolation improves signal integrity and reliability in high-power and electrically harsh environments, making it suitable for battery systems, power electronics, and mobile applications.
Four-Channel Thermocouple Measurement
Four thermocouple inputs allow simultaneous temperature measurement across multiple points in a system. This enables accurate thermal monitoring of components such as cells, modules, motors, or heat sinks without the need for multiple single-channel devices.
Designed for Real-World Systems
ThermoCAN-4 is built for use beyond the lab. Its compact, rugged design and CAN-native output allow it to be deployed in embedded, mobile, and field-based systems where reliability, noise immunity, and clean system integration are critical.
