I. Introduction
The MegaTronXSi microprocessor based controllers are designed to provide a wide range of web monitoring
functions. The controller is programmed through a front panel keypad or via the internet through WebAdvantage
and can be configured to provide a customized web monitoring for your application. Your particular unit’s
functions can be determined by comparing the units model number to the Model Numbering table listed below.

Description of Unit
MegaTronXSi monitors provide WebAdvantage internet based remote monitoring, contolling and reporting
for a wide range of analog and digital appliations.
Control Functions
Each of these control functions are based on a 4-20mA analog input and will include user settable relay control
settings along with a High and Low Alarm setting and Limit Timer. Each control function can control relay
output. When the reading reaches (rises above or falls below) the Set Point the control relay is activated until
the reading changes by the Differential amount.
