CANmod.temp : 4 x Thermocouple-to-CAN [Temperature Sensor]
This thermocouple-to-CAN module produces temperature data from 4 thermocouple sensors and outputs it via CAN bus (standalone) or USB.
Description
This thermocouple-to-CAN module produces temperature data from 4 thermocouple sensors and outputs it via CAN bus (standalone) or USB.
The module supports all thermocouple types (B, E, J, K, N, R, S, T) and can be easily daisy-chained.
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 or temperature telematics.
FEATURES
PRODUCT
Easily add temperature data to any CAN bus system
Add temperature sensor data via 4 thermocouples to your CAN bus - e.g. for use by ECUs or CAN hardware.
l Compatible with any high speed CAN bus (2.0A, 2.0B)
l Fully configure CAN IDs, bit rate and message frequency
l Daisy-chain multiple modules for 8, 12, 16, ... channels
l Power at 5-26 V DC via standard DB9 adapter cables
l Optionally record the data via any CAN interface/logger/...
l Example: Use as add-on for the CANedge (power via 2nd port)
l DBC file included for easy decoding to human-readable form
l White label e.g. for inclusion in your production
Example: Log/stream sensor data

| Cold Junction | ±0.7°C (max, -20°C to +85°C) cold-junction accuracy |
| DATA PARAMETERS | |
| CAN Signals | The module communicates temperatures and fault statuses (for a full list, see the Docs or DBC file) |
| Thermocouple temperatures: The degree celsius (degC) temperature of each thermocouple probe [5 Hz] | |
| Ambient temperature: The ambient temperature measured via internal cold-junction [5 Hz] | |
| Faults: Status of each thermocouple sensor [5 Hz] | |
| CAN BUS | |
