1. Overview
1.1 Introduction
Function
The DR4500A Classic Series recorder combines the simplicity of pen drawn analog traces with the
sophistication of microprocessor controlled functions. This combination results in a user configurable
recorder that is easily adapted to meet a variety of application requirements—from blast furnace to
laboratory.
In addition to recording analog traces, the Classic Series recorder continuously displays process variable
values in the selected engineering units.
Both one-pen and two-pen models accept inputs from any one of a variety of sensors or transmitters within
the configurable range limits. Also, models are available with one or two digital controllers to generate
controlled output signals to operate valves, dampers, heating elements, etc. for process control.
CE Conformity (Europe)
Indicated models of this product are in conformity with the protection requirements of the following
European Council Directives: 73/23/EEC, the Low Voltage Directive, and 89/336/EEC, the EMC
Directive. Conformity of this product with any other “CE Mark” Directive(s) shall not be assumed.
Deviation from the installation conditions specified in this manual, and the special conditions for CE
conformity in Section 2.1, may invalidate this product’s conformity with the Low Voltage and EMC
Directives.
ATTENTION
The emission limits of EN 61326 are designed to provide reasonable protection against
harmful interference when this equipment is operated in an industrial environment. Operation
of this equipment in a residential area may cause harmful interference. This equipment
generates, uses, and can radiate radio frequency energy and may cause interference to radio
and television reception when the equipment is used closer than 30 meters (98 feet) to the
antenna(e). In special cases, when highly susceptible apparatus is used in close proximity, the
user may have to employ additional mitigating measures to further reduce the electromagnetic
emissions of this equipment.
Microprocessor controlled recording and printing
Both the chart and the pen are driven by stepper motors which are controlled by the microprocessor with
configurable chart speed through the keyboard.
The microprocessor uses the configured chart range data as well as the input data to determine the proper
pen position.
The stepper motor accurately positions the pen drive without damping, thus eliminating the need for
slidewire feedback gearing and drive cables.
A configurable deviation recording function lets users show graphically the difference between a reference
input and a process variable input.
Users can designate the channel 1 input or enter a deviation setpoint value as the reference input.

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.
