Introduction

1. Introduction

1.1 Overview

The DirectLine® Sensor for dissolved oxygen measurement in water consists of a

DL424/425 electronics module connected to a DL5000 DO Probe. The modular

electronics design allows the module to be separated from the probe, so that the

probe can be easily removed or replaced while retaining power to the electronics

module.

The DL424/425 electronics module is contained in a Nema Type 4x sealed

weatherproof corrosion/impact-resistant polysulfone housing. The Module can be

mounted as an integral unit directly connected to the probe or remotely using a

probe with a cable. The sealed plastic housing has plug-in connections for the

DL5000 probe and a 4-20 mA output connection.

Figure 1-1 DirectLine® Sensor

9/11 DirectLine® DL424/425 Sensor Module User Manual 1

Introduction

1.2 Electronics Module

The electronics module is loop-powered by 16-42 Vdc and will modulate its supply

current from 4 mA to 20 mA, depending upon the DO value that is measured by the

probe. The transmitted loop current is compensated for process temperature.

A 4-20 mA output connection is provided via a 6m cordset or a customer supplied

cable used in combination with a field wiring connector.

The DirectLine ® electronic module for dissolved oxygen measurements is available

in two configurations:

ppm (DL424) and ppb (DL425).

Figure 1-2 Electronics Module

1.3 Operator Interface

The DirectLine® Sensor operator interface consists of three pushbuttons and one

4-digit, 7-segment LCD display with 3 decimal points, plus (+), and minus (–) signs.

It is responsible for the display of measured values and configuration of parameter

values.
