CAN-2018C - 8 Channel Thermocouple Input
by ICP DAS
|
|
|
|
CANopen Slave Module of 8-channel Thermocouple Input (Analog Input), Current Input
|
|
|
Following the DS-301 version 4.02 and DSP-401 version 2.1, the CAN-2018C module allows access to thermocouple input status and configuration settings through standard CANopen protocol. CAN-2018C has passed the validation of the CiA CANopen Conformance Test tool. This device can be used with standard CANopen master through use of the EDS file.
The CAN-2018C is a 10-channel universal analog input CANopen slave module that has voltage and current input types. It provides extremely accurate thermocouple measurement and automatic cold-junction compensation for each channel.
