This Honeywell Digital Controller is a high-performance, microprocessor-based instrument that offers a high degree of functionality and reliability. Known as the DC2800, it is designed to provide precise control for a variety of process automation applications. The controller features an easy-to-read dual display, with the primary display showing process variable (PV) and the secondary display indicating set point value (SPV). It operates on a 100-240 VAC power supply and has an operating temperature range of -10 to 55 degrees Celsius. The DC2800 also supports various input types including thermocouple, RTD (Resistance Temperature Detector), DC current, and DC voltage. It offers several output options such as relay, triac, linear voltage, and current outputs for driving different types of actuators. The controller's advanced PID (Proportional-Integral-Derivative) algorithm ensures accurate control under varying process conditions.
