Note: Probes not includes, sold separately
This thermocouple-to-CAN module produces temperature data from 4 thermocouple sensors and outputs it via CAN bus. The module is 100% standalone - no PC required.
The module supports all thermocouple types (B, E, J, K, N, R, S, T) and can be daisy-chained for 8, 12, 16, ... channels.
You can integrate the module with any CAN bus system - e.g. to provide temperature data for your ECUs or existing CAN hardware.
As an example, you can use the module as an add-on for the CANedge - ideal for e.g. engine dynos, EGT analysis, HVAC monitoring and other temperature telematics use cases.
Add temperature sensor data via 4 thermocouples to your CAN bus - e.g. for use by ECUs or CAN hardware.:
- Compatible with any high speed CAN bus (2.0A, 2.0B)
- Fully configure CAN IDs, bit rate and message frequency
- Daisy-chain multiple modules for 8, 12, 16, ... channels
- Power at 5-26 V DC via standard DB9 adapter cables
- Optionally record the data via any CAN interface/logger/...
- Example: Use as add-on for the CANedge (power via 2nd port)
- DBC file included for easy decoding to human-readable form
- White label e.g. for inclusion in your production

Configuration:
- Bit Rate: Select between standard bit rates (5K to 1M) or use custom bit-timing
- Enable/Disable: Individually enable/disable the CAN message
Identifier Customization Individually configure the CAN ID (11-bit or 29-bit)
- Push/Poll Mode: Individually configure 'trigger' modes for the CAN messages (push or poll)
- Frequency: Individually configure prescaling of the CAN message frequencies to lower rates
