GS3100 Weigh/Batching Front End

The Batching Controller That Talks And Listens

The GS3100 Remote Computer/PLC ‘Talks’ To Your Factory Floor Operator. 

Write Messages to the Display and operate factory machines in foreground or background mode. Send Weight in Stream or On-Demand mode.

Key Features:
  • NOW with ANALOG Output OPTION6HPF for 4-20mA & 0-10VDC 14bit (1:16,000) Accuracy.
  • MODBUS RTU & ASCII Option Available.
  • A World First – the First Weight Indicator designed from the ground up as a Front End for Computer/PLC Controlled batching.
  • Computer/PLCs can use the GS3100 to talk to “factory floor” operators in the plant or across the World. The remote Computer/PLC can completely control the GS3100 including using the GS3100′s display to show messages and the GS3100′s keyboard for operator inputs. (Requires I/O Option)
  • Turn serial stream data ON and OFF as required. The remote Computer/PLC can turn-on and turn-off the GS3100′s serial weight data stream to obtain high speed weight data only when needed during time critical periods. (Requires I/O Option)
  • Standard “no-extra cost” RS-232 Serial Output supplies weight data at 4800 or 9600 baud to 20 times per second.
  • Year 2000 Compliant in every respect.
  • Full Range of Programmable Settings. The GS3100′s extensive range of keyboard programmable settings allows it to be “customized” to suit any application. All weight calibration and set up is entirely carried out using the GS3100′s keyboard.
  • Standard Dual Optically Isolated Set points for High and Low Alarms – a vital safety measure. 5-48VDC 1Amp outputs can drive solenoids and relay coils.
  • Full SIX wire load cell connection automaticallyand accurately compensates for long load cell cable runs typical in weigh/batching applications. NOTE:- FOUR wire products cannot compensate for long cable runs which can result in errors of 10% or more.
  • Assured and Guaranteed Accuracy and Stability. Every GS3100 shipped has spent one day in our “oven” cycled between operating temperatures of -10oC and +40oC. Its accuracy and stability has been checked and meets or exceeds our specification. Guaranteed – you can rely on it.
  • High Speed 20/second operation tuned to provide rapid response.
  • Easy to mount short body enclosures – 150mm Body length and 180mm total depth with connectors allows installation into a standard 200mm depth enclosure.
  • Easy to Calibrate. Display any weight to 199990 settable with display resolution of 400 to 10,000 divisions and adjustable “count by” settings 1, 2, 5, 10, 20 and 50 – all set via the GS3100′s keyboard.
  • Added security – the GS3100 records all attempts to access its set up and calibration settings – this information is displayed when power is applied – it is also available with the use of an optional serial I/O card. Operator friendly sensibly sized keyboard and display – 12mm keys and 14mm display.
