sophisticated weighing indicator
with 16 bit internal resolution and
very fast A/D conversion rate.

Direct communication with the PC’s
bus and high frequency sampling
enable the LCIC-1106A to handle
real time applications impossible
with external indicators via serial
communication.

The stand-alone microcomputer
based interface card, requires no
other interfacing accessories, simply
connect the load cell directly to the
card and you are ready for calibration.

The LCIC 1106A is a load-cell
interface card for the IBM PC/AT
and compatible computers. It will
accept any type of strain gage
based load cell. Each card can read
one load measurement. The card
will directly power up to six 350Ω
load cells wired in parallel. In fact,
it is a completely stand-alone

software shown.

TYPICAL APPLICATIONS:

• Gravimetric Filling Systems

• Batching Controllers

• Loss-In-Weight and continuous weighing controllers

• Hi speed check weighers

• Multi scale processing–by using more than one LCIC

• Weighing in motion (like trucks on the roads)

• Multi head filling machines

• Measuring and analyzing forces in press machines

MAIN FEATURES:

• User friendly calibration procedure with automatic zero
and gain adjustment.

• Calibration parameters reside in the LCIC’s memory,
retained even if the card is moved from one PC
to another.

• Calibration library. Up to four calibrations may be stored
simultaneously on the board, and an unlimited number
of calibrations may be stored on disk for later use.

• No auxiliary power supply required. The LCIC powers
and senses 6-wire load cells.

• Provides data in weighing units (kg, gr., lb., ton)
in ASCII or floating point–usable by almost any
programming language.

• Opto-isolated I/O lines enable logic control through
user’s application program.

SOFTWARE INCLUDED:

• Mapping memory diagnostics–for easy address
selection to install the card.

• User-friendly calibration software.

• I/O check and test procedure built into the calibration
software.

• Software to utilize PC as a weighing indicator,
counting scale and check-weigher.

• Examples show how to communicate with the board
under DOS. Drivers included for Windows 95/98.
