China Longxin Weighing Controller JY500A is the next step in the evolution of the JY500 series Weighing Controllers. With its high speed data conversion and versatile configuration, is it any wonder the JY500A was given the excellence in product design award by the Ministry of International Trade and Industry (China Longxin ).

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 PLC’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.
