RTD - Resistance Temperature Device Inputs
The CAN-CBX-Pt100 is designed for the direct connection of up to four temperature sensors. Simple resistance measurements can also be performed. Pt- and Ni-resistance sensors are supported. The sensor resistors can be connected in two- or four-wire configuration. The conversion of the four sensor resistor inputs is realized by four independent ??-converters. Linearisation according to NIST is achieved by the on board microcontroller.
CAN Interface and LED Display
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. Four LEDs indicate the module and CANopen node status.
InRailBus
The CAN-CBX-PT100 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 from the InRailBus without interrupting the bus signals.
Software Support
The module comes with CANopen firmware according to CiA 301and supports the CiA 404 profile for measuring devices.
