Introduction
The SUP-MDC-P2 is an intelligent dual-channel universal controller designed for advanced online process monitoring and water quality analysis. It supports both analog and digital sensors, allowing simultaneous measurement of multiple process parameters through a single controller. With isolated 4–20 mA outputs, Modbus RTU communication, optional NB-IoT or 4G wireless connectivity, and a 4.3-inch full-color touchscreen, the controller provides reliable monitoring, remote communication, and process control for industrial automation, water treatment, and environmental applications.
