Description
Application Scenarios:
In a Taiyuan-based municipal water treatment plant, the PM590-ETH serves as the central controller for a filter backwash and chemical dosing station. The CPU reads analog signals from pH and turbidity sensors via expansion modules, controls pump speeds through its serial port (Modbus RTU), and uses the Ethernet port to transmit process data to the plant’s SCADA system. The onboard LCD display allows maintenance engineers to quickly check the system status (e.g., “Filter 3 Backwashing”) without needing a connected laptop, reducing troubleshooting time during routine inspections.
