Specification

The CANmod.temp Specification

GENERAL
Functionality	The device supports 4 x thermocouples for outputting temperature sensor data via CAN bus
Included	CANmod.temp module, USB dust cover (thermocouple sensors and mini USB adapter not included)
Firmware	Supports free firmware updates via USB for adding features
Configuration	Configuration files based on the popular open source JSON schema concept (similar to the CANedge)
Software	Free open source editor tool for easy device configuration (offline/online version available)
Safety	CE, FCC, IC and RoHS certified (see the Docs for certificates)
Warranty	1-year warranty
Support	Free, fast & high quality support
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
Types	Supports thermocouple types B, E, J, K, N, R, S, T (via configuration)
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
Input Supply	+5V to +26V DC via the DB9 connector (power via pin 1 or pin 9)
Power Consumption	Extremely low (<1W) - no risk of battery drainage
Protection	Reverse voltage protection on CAN-bus supply
	Transient voltage event protection on supply lines
MECHANICAL
Enclosure & Weight	Compact aluminium enclosure: 52.5 x 70.0 x 24.5 mm (L x W x H), 80 grams
Connector (Front)	1 x Standard D-sub 9 (DB9) connector
Connector (Back)	4 x miniature thermocouple female connectors
Pin-Out	See the product manual for the DB9 connector pin-outs
USB	Standard mini USB connector for config/firmware updates and streaming (USB cable not included)
LEDs	Module status via 3 external LEDs: Power, CAN bus, Memory
Temperature	Operating temperature (CANmod.temp module): -25degC to +70degC
IP Rating	IP Rating 40
Mounting	Module can be mounted via e.g. rugged double-sided tape, zip-ties or a mounting bracket

CANmod.temp: 4 x Thermocouple-to-CAN Temperature Sensor (excl.probes)

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 thermocouple to can bus module supports all thermocouple types (B, E, J, K, N, R, S, T) and can be daisy-chained for 8, 12, 16, ... channels.

Explore our I/O modules.

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.
