DeviceNet is one kind of network protocol based on the CAN bus, it's mainly used for the embedded network of the machine control, such as industrial machine control, aircraft engines monitoring, factory automation, medical equipments control, remote data acquisition, environmental monitoring, packaging machines control, etc.
The CAN-2018D follows DeviceNet specification Volume I/II, Release 2.0. User can access the thermocouple input status and set the configuration via DeviceNet EDS file. CAN-2018D has 8-channel thermocouple input and it can be used for various applications. By the DeviceNet masters of ICP DAS, you can quickly build a DeviceNet network to approach your requirements.
