Honeywell R4500 Classic Parts List

10.1 Overview

Introduction

This section provides the replacement parts lists for the DR4500A Clasic Series Recorder. Most parts are
supplied on an optimum replacement unit basis; that is, part numbers are given for complete printed circuit
boards rather than for individual PCB components.

The figures that follow are exploded views of the DR4500A recorder. Each part is labeled with a key
number and the key numbers are listed in tables with associated part number.

Also included for your reference are an Internal Cabling drawing (Figure 10-5) and an Internal Wiring
Diagram (Figure 10-6) for options only.
