Product Description
SIIHANN MWM300 Temperature Transmitter
The SIIHANN MWM300 is a high-precision industrial temperature transmitter module designed to convert signals from Pt100 RTD sensors into standardized industrial outputs. Engineered for reliability and versatility, it accurately measures temperatures within a 0 to 150°C range. A key feature of the MWM300 is its dual-output capability, providing both a 4-20mA current loop signal and a 1-5V voltage signal simultaneously. This allows for flexible integration with a wide variety of PLCs, data loggers, and control systems. The module supports both 2-wire and 3-wire Pt100 connections and operates on a wide 18-60V DC power supply, making it a robust solution for various industrial automation and process control applications.
