China Longxin Weighing Controller JY500A intro
Standard SI/FII 2-wire high speed (300kbps) bi-directional serial interface allows up to four controllers to communicate with up to 16 peripherals. The E928 (SI/FII to Open DeviceNet) E920 (serial SI/FII to various PLCò€™s), M350 (printer) LD517 (remote display with accumulator) or E232 (SI/FII to RS232C converter) are easily connected with a total communication distance of over 900 feet (300m).The Weighing Controller JY500A is a versatile controller for Hopper scales, Packing scales and Multi-Ingredients Batching. Add to that, the JY500A-X1 for In-motion Check-weighing Indicator and JY500A-X2 for Weigh-in-Motion Truck Axle indicator, and you have a powerful selection for precision weighing and process weighing control accuracy.
