Analog Inputs
The CAN-CBX-AI420 module is equipped with two precision, high throughput analog front ends with ΣΔ A/D-converters that in common offer four analog input channels.
Depending on the selected sample rate and the external wiring a resolution of at least 20 bit can be achieved. The input voltage range is programmable.

Compact I/O Module
The CAN-CBX module series with InRailBus provides industry compatible CAN bus in-/output modules in combination with service-friendly ‘wiring’ of CAN bus and supply voltage.

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.

The CAN-CBX-AI420 features the possibility to connect the power supply and the CAN bus signals via the InRailBus connector
(CAN-CBX-TBUS connector) integrated in the mounting rail. Individual modules can then be removed from the InRailBus without interrupting the bus signals.

Software Support
The CAN-CBX-AI420 comes with CANopen firmware according to CiA 301 and and with a CANopen-I/O profile according to CiA 401.
