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.

| Origin | Denmark |
| SENSOR (temperature) | |
| Channels | Supports up to 4 thermocouple sensors/channels (plus ambient temperature via cold-junction) |
| Module | Professional-grade MAX31856MUD+ precision thermocouple converter |
| Temperature Range | Supports a range of -210°C to +1800°C (depending on thermocouple type) |
| Formatting | The module conveniently outputs degrees celsius via automated edge linearization |
| Accuracy | Lab-grade thermocouple voltage measurement accuracy with cold junction compensation |
| Resolution | 1 degC resolution (in 1 CAN frame) and/or 0.01 degC resolution (in 2 CAN frames) |
| Note: The 0.01 degC resolution typically exceeds the practical probe accuracy | |
| Protection | Thermocouple inputs are protected against overvoltage conditions up to ±45V |

| Filtering | Line frequency filtering of 50Hz and 60Hz (via configuration) |
| Fault Detection | Thermocouple fault detection (open thermocouples, over- and undertemperature) is communicated via CAN |
| 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 | |
| Channels | 1 x CAN channel |
| Modes | The device can either broadcast the data onto the CAN bus - or provide it on-request |
| Standard | ISO 11898: Compliant with CAN (between 5K and 1 Mbit/s baud rates) |
| Identifiers | Compliant with CAN specifications 2.0A (11-Bit ID) and 2.0B (29-Bit ID) |
| Termination | Termination can be toggled via switch below DB9 connector |
| Retransmission | Retransmission of frames that have lost arbitration or been disturbed by errors |
| Transceiver Protection | Protection: +/- 25kV HBM ESD, +/-12kV IEC ESD, +/-14 V bus fault, short circuit |
| Common mode input voltage: +/-12V | |
| TXD dominant timeout (prevents network blocking in the event of a failure) | |
| 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 |
| Thermocouple Type | Specify the thermocouple type for each channel (e.g. Type K, Type J, ...) |
| Line Noise Filtering | Select rejection of 50 Hz (EU) and its harmonics or 60 Hz (USA) and its harmonics |
| ELECTRICAL | |
