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.
