Module13.2 Dual Kmeter

SKU:M127

Description

Module13.2 Dual Kmeter is a dual-channel K-type temperature measurement module based on the "MAX31855KASA + stm32f030f4p6 + electrical isolation" solution. The module features two K-type thermocouple sensor interfaces, and uses a signal relay to alternately measure the temperature values of the two channels. It supports a measurement range of -200°C to 1350°C with an accuracy of ±2°C. Additionally, the module includes B0505LS-1WR2 and CA-IS3020S voltage and signal isolation chips, ensuring system stability and safety. The module also has a built-in DIP switch for easily switching different I2C addresses to meet various application needs. It can be used in industrial automation, instrument detection, and other scenarios.
