DRH555-controller

Product Description

It features a dual display (PV/SV) with a large, clear LED readout, making it easy to monitor and set parameters. The controller supports universal input (thermocouple, RTD, and linear signals) and offers flexible output options including relay, SSR drive, and 4-20mA analog output. With its advanced PID control algorithm and auto-tuning function, the DRH555 ensures stable and accurate temperature control, reducing overshoot and improving process efficiency. This controller is housed in a compact 1/16 DIN (48x48mm) case, suitable for panel mounting. It operates on a universal power supply of 100-240VAC, making it versatile for various installations. The DRH555 includes multiple alarm outputs, a ramp-soak function, and communication options (RS485 Modbus) for integration into larger control systems. Its robust construction and compliance with international standards make it a reliable choice for demanding industrial environments. The UHT DRH555 is widely used in plastic molding, packaging machinery, food processing, and HVAC systems. Its user-friendly interface and programmable functions allow for easy configuration and operation. Whether for retrofitting existing equipment or new installations, the DRH555 provides a cost-effective solution for precise temperature control. With a wide range of input types and output configurations, it can be tailored to meet specific process requirements. The UHT DRH555 is a high-performance temperature controller designed for precise temperature management in industrial processes.

Technical Specifications

Version & Model Difference

The UHT DRH555 series may have different versions based on output configuration and communication options. Standard versions include relay output, SSR drive, and analog output. Some versions come with RS485 communication as standard, while others require an optional module. Additionally, there are versions with different alarm configurations (e.g., 2 alarms vs 3 alarms). It is important to verify the exact model code to ensure compatibility with your system. The DRH555 is an upgraded version of the older DRH-555 series, offering improved accuracy and additional features like ramp-soak.
