*Name: Weighing controller system
*Model: XK3190-C8
Introduction: Weighing indicator XK3190-C8 adopts fast speed A/D conversion technology. It is widely applied in electronic batching scale electronic fix-value scale and electronic catchweigher, sort of control system. Meanwhile, it has function for max and min limitation alarm and peak value preserving.
Standard Function:
*3 inputs, 3 outputs (3 output relays inside) contro
*High precision A/D conversion with readability 1/30000
*With 5 points nonlinearity amend
*If change the former indicator, no need to re-calibrate, only to input parameter of former indicator
*Embodies with automatic gravimetric filling instruments, catchweigher, alarm for max and min limitation and peak value preserving functions
*Able to set fixed-value, pre-act value, max-min limitation, and delay time freely based on different applications
*1-2 materials available for plus/minus scale; External, self-testing, and free max and min modes are available for catchweigher
*Standard RS-232/422/485 communication interface, baud rate and way of communication is optional
*Standard scoreboard interface serial sending signal by 20mA current loop (constant current)
*Precise simulate signal output with mode of 4-20mA/0-20mA/0-5V/0-10V optional, adjustable
*Accumulative weight and times is able to be stored, check, delete, and with date-protection when power cut off
*Able to connect with serial printer to print weighing record, accumulative amount or combined information, kg, t, g, lb, is an optional print unit
*Zero tracking, range for zero (automatic and manual) is free to be set
*Strong anti-jamming and reliability
