1. Overview

1.1 Description of the Module

Fig. 1: Block circuit diagram of the CAN-CBX-THERMO module

The CAN-CBX-THERMO module is a CAN-CBX module with four High Resolution
Thermocouple Interfaces.
The CAN-CBX-THERMO is equipped with four independent sigma-delta A/D converters for the
evaluation of thermocouples. It features support of J, K, B, E, N, R, S and T thermocouples.
Depending on the selected sample rate and the external wiring a resolution of at least 1

h

V can be

achieved.
For cold junction compensation the temperature of the sensor clamp is measured by a digital
temperature sensor.

The conversion of the four thermocouple inputs is realized by four independent

ij

-converters.

Linearisation according to NIST is achieved by the on board microcontroller.

The CAN interface is designed according to ISO11898-2 high-speed layer with electrical isolation
and supports bit rates up to 1 Mbit/s. The CANopen-node number and the CAN-bit rate can be
easily set via coding switches.

The CAN-CBX-THERMO features the possibility to connect the power supply and the CAN bus
signals via the InRailBus connector (TBUS-connector) integrated in the mounting rail. Individual
modules can then be removed without interrupting the bus signals.

The module comes with CANopen

®

firmware according to CiA

®

301 and supports the CiA 404

profile for measuring devices.
