The Model 428 is the simplest and easiest to use 4 channel pattern controller available on the market today. Each channel is capable of being programmed for two separate events each a line, dot or stitch pattern. The 428 high power constant current outputs can be configured to allow you to operate many different types of glue or tape applicators. The 428 allows real time adjustments to its outputs, making it simple for operators to get the exact pattern needed. The systems distance based pattern stitching capability allows each event to be programmed to apply multiple glue patterns. Features such as 4 optical sensor inputs dual encoder inputs proportional control of glue pressure and shutter and pump controls make the 428 a very versatile controller.
