Specification

SEODescription

The A-200FAF-PH sensor is a versatile industrial module designed for precision monitoring and control applications. It integrates a high-accuracy pH sensor with a compact A-200FAF-PH controller, offering 4 analog inputs (0-10V/4-20mA) and 2 relay outputs for direct device control. The A-200FAF-PH module supports RS-485 and Modbus RTU communication, enabling seamless connectivity with PLCs, SCADA systems, or up to 32 peripheral devices in a single network. Operating at 12-24V DC, it functions reliably in harsh environments (-20°C to 60°C) and is widely used in water treatment, chemical processing, and food production. Key advantages include IP67-rated durability, automatic temperature compensation, and real-time data logging. However, its calibration requires specialized tools, and the pH electrode has a limited lifespan in highly abrasive media.
