  • Page 15: Introduction

    1.1 Overview Function The UDC3500 is a microprocessor-based stand-alone controller. It combines a high degree of functionality and operating simplicity in a 1/4 DIN size controller. This instrument is an ideal controller for regulating temperature and other process variables in numerous heating and cooling applications, as well as in metal working, food, pharmaceuticals, semiconductor, testing and environmental work.

  • Page 16: Analog Inputs

    Introduction Analog Inputs The UDC3500 has three universal analog inputs with a typical accuracy of ±0.10% of full-scale input and a typical resolution of 16 bits. These can be configured to act as one Universal and four High Level Inputs for a total of five analog inputs. All analog inputs are sampled six times per second (every 166 ms).

  • Page 17: Digital Inputs

    Also, two of these digital inputs can allow one of six additional selections to be combined with one of the above selections. Outputs Output Types - The UDC3500 may have up to seven of the following outputs: • Current Outputs (4-20 or 0-20 mA) • Electromechanical Relays (5 amps) •...
  • Page 18 • Diagnostic Alarm Communications A communications link is provided between the UDC3500 and a host computer or PLC via the RS422/485 Modbus® RTU or Ethernet TCP/IP * communications option. An infrared communication link is also available allowing a non-intrusive configuration of the instrument.
