Introduction
Introduction
The MXD73 is a microprocessor controlled multi-parameter instrument that can be
installed with a user selected combination of up to 3 Sensor Input Cards. The instrument
may be subsequently modified to meet changing requirements by the installation of
additional, or different, cards and the attachment of the appropriate sensor(s).
Utilising a multifunction easy to read QVGA LCD the instrument displays readings and
provides feedback to the operator on the status of the sensors and instruments outputs.
In addition the instrument features, depending upon configuration, up to six control relays
and up to six 0/4 – 20mA current outputs. These can be used to provide fully configurable
control, alarm and feedback.
Finally the instrument also features an SD card interface which enables the user to backup
and restore instrument settings, copy settings between instruments, log the sensor
readings (optional extra) and to upgrade the instrument’s software.
