DataView™ LI55 Level Controller

INTRODUCTION

The DataView LI55 is a multi-purpose, easy to use digital process meter ideal for
level, flow rate, temperature, or pressure transmitter applications. It accepts
current and voltage signals (e.g. 4-20 mA, 0-10 V). Three of the front panel
buttons can be custom-programmed for a specific operation. The analog input
can be scaled to display the process in two different scales; for example the main
display could indicate level in feet and the second display could indicate the
volume in gallons.
The basic model includes an isolated 24 VDC transmitter power supply that can
be used to power the input transmitter or other devices. An additional isolated
24 VDC power supply is included with the 4-20 mA output option. A digital input
is standard.
A fully loaded LI55 meter has the following: four SPDT relays, 4-20 mA output, and
two 24 VDC power supplies. The LI55 capabilities may be enhanced by adding a
four SPST relays expansion module (creating an eight-relay process meter).
The eight relays can be used for alarm indication or process control applications,
such as pump alternation control. The 4-20 mA isolated output, and digital I/O
options make the LI55 an excellent addition to any system.
