5/00 UDC3300 Expanded Model: DC330E User Manual 1
1. Introduction
1.1 Overview
The UDC 3300 is a microprocessor-based, stand-alone controller. It combines the
highest degree of functionality and operating simplicity offered in a 1/4 DIN size
controller.
With a typical accuracy of ± 0.20 % of span, the UDC 3300 is an ideal controller for
regulating temperature and other process variables in numerous heating and cooling
applications, in metal working, food, and pharmaceuticals, and testing and
environmental work.

Deviation Bargraph
• Center bar indicates PV is 
within ±1% of setpoint. 
• Next bar will light if PV is 
between ±1% but less than  
±2% in deviation. 
• If PV is equal to or greater than 
±10% deviation, the center bar 
plus all ten deviation bars will 
light.
