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

Write message 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 option 6HPF for 4-20mA & 0-10VDC 14bit (1:16,000) accuracy
• MODBUS RTU & ASCII option available
• 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 automatically and 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
