The CAN-CBX-Pt100 module by ESD Electronics (Germany) provides analog inputs for temperature sensors (RTD). It complies with the CiA 301 and CiA 404 specifications.
THE CBX SERIES IS A LINE OF COMPACT CANopen I/O modules. Each module conforms to ISO 11898-2 physical layer and supports bit-rates up to 1 Mbit/s. The internal CAN/CANopen interface is electrically isolated; the internal firmware is adaptable to individual customer requirements.
In particular, the CAN-CBX-Pt100 module allows the reading of four temperature sensors (RTD) through a two- or four-wire connection. The resolution is adjustable in a range of 0,1 °C to 0,0001 °C. In addition, the module provides setup options for the RTD channels:
The supported sample rate range goes from 2,5 to 1000 samples per second. The module supports sensor types such as Pt100, Pt200, Pt500, Pt1000, Pt5000, Ni100, Ni200, Ni500, Ni1000, and Ni5000. The linearization is managed by the internal micro-controller according to NIST, and the offset and gain can be adjusted manually.
