SC1200B-8 intelligent temperature alarm controller is an industrial MODBUS-RTU protocol temperature controller, supporting 8-channel one-wire temperature acquisition, 8-way alarm control relay output, 160 point 10-channel temperature one-wire temperature acquisition, supporting 350 meters ultra-long sensor bus.
The SC1200B-8 is an 8‑channel, 160‑point smart temperature controller that uses MODBUS‑RTU for industrial monitoring and alarm functions. It supports long‑distance sensor buses up to 350 m and provides eight independent relay outputs for alarm control.
The manual describes the hardware interfaces, key operation steps, communication protocol, command set for data queries, relay status, sensor auto‑search, and configuration of alarm thresholds. Typical applications include SMT lines, electronic equipment factories, cold storage, warehouses, GMP monitoring, and telecom rooms. This manual is written in Chinese.
