GSI302 Digital Weighing Indicator Controller
* Selectable of four program mode: self-control or external-control catch weigher, plus or minus Automatic gravimetric filling instruments. The catch weigher can be set to be general catch weigher and peak-value maintenance scale. It can store 5 batching material used as fix-quantity scale or catch weigher
* Able to set digital filter intensity, A/D conversion speed
* Weighing data save, check and delete, protection in case of power off
* Real-time clock without effect on power off
* Standard: 8 input, 2 of them can be high speed counting input, coder input or interrupt(high speed reflection) input; 8 output(optional for relay box). Be able to fix-quantity control of two materials for standard program
* Input & output can be expanded, each IO expanding box can be expanded to 8 on/off input and 8 on/off output. The max. connection number of IO expanding box is four. Total quantity of IO is 40 input and 40 output
* 2 separate serial communication interface, one is RS232, another is RS232/RS422/RS485/Modbus for selection, with two communication ways by continuous sending or on command method
* Parallel/serial print interface, able to connect many kinds of printers
* Chinese/English weighing data, accumulation, batching material or calibration can be printed
* Optical isolation 20mA current loop scoreboard display interface
* Optical isolation 4~20mA/0~5V/0~10V analog output(optional)
