1 Introduction
1.1 Overview
The UDC 2300 is a microprocessor-based stand-alone controller. It combines
reliability and operating simplicity in a cost-effective 1/4-DIN size controller.
The UDC 2300 monitors and controls temperatures and other variables in
applications such as environmental chambers, plastic processing machines,
furnaces and ovens, and packaging machinery.
Its features include:
• Universal AC Power Supply,
• Input/Output Isolation,
• Isolated Auxiliary Current Output / Digital Input,
• Modbus and ASCII Communications,
• Timer,
• Accutune II Tuning with Fuzzy Logic Overshoot Suppression,
• 2
nd
Input (Remote Setpoint),
• Setpoint Ramp/Rate/Program,
• Three Position Step Control,
• Duplex (Heat/Cool).
The UDC 2300 is also downward compatible with existing UDC 2000
applications and installations except for RTD and 0-10 Volt inputs.
