N4KTA01 K-Type Thermocouple to RS485 Converter – -200 to 1350°C Modbus RTU Digital Temperature Measurement Board for PLC Industrial Automation
N4KTA01 K-Type Thermocouple to RS485 Converter – -200 to 1350°C Modbus RTU Digital Temperature Measurement Board for PLC Industrial Automation
N4KTA01 is the RS485 K-type thermocouple collector developed and produced for the first time by eletechsup. Through this module, the temperature value of the K thermocouple can be converted into a digital quantity and transmitted through RS485. If the accuracy requirements are not high, you can use version A. If the accuracy requirements are high, it is recommended to use version B.
