This product is a multi-channel temperature acquisition module based on the RS485 communication bus. Specifically designed for industrial scenarios requiring multi-point, high-frequency temperature monitoring, it can simultaneously accommodate 8 digital temperature sensors produced by our company. The module integrates industrial-grade protection circuits, including reverse power connection protection, transient voltage suppression for the RS485 interface, and communication error checking functions, which effectively resist on-site electromagnetic interference and ensure the integrity and security of data during long-distance transmission. Its wide voltage input and terminal block connection method make installation and wiring extremely simple, making it an ideal choice for building reliable automated temperature measurement systems.
