Introduction to Batching Control Instrument

JY500A4 Series weighing batching-controller is designed as the control unit of batching weighing instrument adding various materials in a weighing hopper. 

JY500A4 Series weighing batching-controller adapt pocket-size case, it  has two rows of LED display and four keys，which is easy to use and learn.

Features 
●Pocket-size case, compact panel, two rows of LED display, four keys, easy to use and learn.
●Can control 4 different material proportioning. 
●Can inch material during feeding.
●Power-off protection, it can continue to batch after restart the instrument.
●May set batch number. it can automatically stop when finishing the set batch number.
●Various communication interfaces and protocols.
●Internal integrated switch power can work normally when voltage fluctuation is below 40%.
