Overview
Introduction
Digital controller
The DR4500A recorder includes an integral microprocessor-based, PID controller with two loops of
control. A variety of output types, including a duplex variation for heat cool applications, lets you select the
output that is right for your final control element.
You can configure the control action as On-Off, PID-A, PID-B, or PD with manual reset. English language
prompts guide you through the entry of all the controller's configurable parameters.
Construction
The DR4500 recorder is housed in a molded case which can be panel or surface mounted. A glass or acrylic
windowed door protects the internal components while allowing easy access to the chart and operator
interface. An optional external keypad that allows operator selections without opening the door is available.
Circuitry is partitioned on printed circuit boards for ease of service.
Power, input, and output wiring connect to terminations inside the case. Knockouts in the sides and bottom
of the case accept conduit connections for convenient wire entry.
