SCT2002 intelligent temperature alarm controller adopts the latest imported digital sensor, high precision, corrosion resistance, long life, wide range, good performance, can work stably and reliably in various environments for a long time. It has RS232 interface and can communicate with computers or industrial control equipment.
The SCT2002 intelligent temperature alarm controller provides high‑precision temperature measurement (0.1 °C resolution, 0.5 °C accuracy) over a wide range of –55 °C to 125 °C. It features a panel‑type design with RS232 communication and optional CAN, RS485 or Ethernet interfaces, suitable for indoor and outdoor monitoring, including underwater applications.
The manual details the device’s mechanical specifications, installation method, wiring diagrams, display panel operation, and configuration procedures such as setting alarm limits, sensor channels, and communication parameters. It also includes the MODBUS‑compatible protocol for integration with industrial PLCs. This manual is written in Chinese.
