The ADAM-6018 8-channel thermocouple input module is the most prevailing temperature sensor in today’s industrial automation market. In addition to 8 T/C input channels, the ADAM-6018 is also equipped with 8 digital output channels such as auxiliary alarm outputs or pure outputs. Last but not least, the ADAM-6018 comes with an external DIN-rail terminal board for wiring between the ADAM-6018 module and the field sensor. This special wiring mechanism greatly enhances the accuracy and reliability for thermocouple measurement in environmental and facility monitoring applications.
