LCIC-1106A Load-Cells Interface Card
For PC/AT or Compatibles
LCIC-1106A, $990, shown with optional LCIC-1107 I/O module.
Compatible With All Load
Replaces All
Conventional Weighing Indicators. Card Resides Directly On Computer Bus, Thus Eliminating Slower RS-232 And Other Communication Ports
Suitable For All Dynamic,
Force Measuring And Real Time Applications
Ultra Fast A/D
Conversions (400 Per Second After Filtering)
Optional I/O Card
(8 Outputs And 4 Inputs All Opto-isolated)
Up To 16 Cards May Be
Installed In One PC
Includes Utilities For
Easy Installation And Calibration. Also Includes OCX Drivers For Windows 95/98 With Examples For Visual Basic And C++
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 350 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.
