Product Description

J/K/T/E/R/S/B Type Thermocouple Signal Converter RS232 RS485 Converter Data Acquisition


The model selection of SY AD-02T series is just initial type of thermocouple which supports by the module. User can change the types of thermocouple by re-configurating the module through ASCII character command, then calibrate it.
SYAD08T series modules support both RS232 and RS485 communication interface. User can choose the communication interface according to the application environment, and at the same time only one interface works,otherwise it may interference with each other.
