Product Description

The NX-AD4203 temperature controller is a compact, high-precision PID controller designed for industrial automation. It features 4 universal analog inputs (supporting thermocouples, RTDs, and 0-10V/4-20mA signals) and 2 relay/SSR outputs for direct control of heating/cooling systems. The NX-AD4203 digital module integrates RS-485 communication with Modbus RTU protocol, enabling seamless connection to up to 32 devices in a network. Operating within 12-24VDC power input and a -20°C to 70°C ambient range, it's ideal for HVAC, food processing, and pharmaceutical applications. This DIN-rail mounted controller offers 0.1% measurement accuracy, programmable PID parameters, and automatic tuning. Notable advantages include its modular design and real-time temperature tracking, while limitations include no built-in Wi-Fi or battery backup. The 3.5-inch LCD provides clear process visualization with adjustable sampling rates up to 100ms.
