CAN-CBX-PT100/2CANopen® Module for Precise Measurement of Temperatures Temperature and Resistance Measurement with high Resolution • Wide temperature application range with flexibility in choice of Pt or Ni probes. • High-precision measurements with adjustable resolution and 4-wire connection technology • High-accuracy resistance measurements with two selectable sensing currents CANopen® Integration according to CiA® Specifications • Robust CANopen communication according to CiA specifications • Compatibility and interoperability with CiA 301 CANopen application layer and communication profile • Generic I/O-module providing versatile integration capabilities with CiA 404 CANopen profile for measuring devices Extensive Configuration Options for each • High flexibility thanks to adjustable analog-to-digital conversion rate from 2.5 to 1000 sps • Accurate temperature measurement using NIST standard linearization • Precise data acquisition under changing conditions due to automatic calibration Accurate Measurements and easy Calibration The CAN-CBX-PT100/2 is designed for the direct connection of up to four temperature sensors. Simple resistance measurements can also be performed. The conversion of the four sensor resistor inputs is realized by four independent IA-converters. CAN Interface with Galvanic Isolation The module features a CAN interface compliant with ISO11898 standards. It offers galvanic isolation and supports bit rates up to 1 Mbit/s. CANopen node number and the CAN bit rate are configured conveniently via coding switches. Efficient I/O Integration Within the CBX module series, the InRailBus technology offers compact industrial CAN input/output modules. These modules feature an efficient wiring concept for CAN and supply voltage and are housed in a slim design that focuses on usability. Advanced InRailBus Integration The InRailBus connector (TBUS connector) simplifies the supply of power and CAN bus signals. It is seamlessly integrated into the DIN rail for user-friendly installation. At the same time, individual modules can be removed from the InRailBus without interrupting the bus signals, which enables efficient maintenance. Alternatively, power and signals can also be connected separately via the terminal connections. Comprehensive LED Status Display Four LEDs clearly visualize the status of the CANopen node and the module status.
