Model 3204 1/4 DIN controller has a text display, high accuracy input, five on-board process recipes (48 parameters per recipe), Instant Accuracy® system and an optional Amp-meter display from a CT input. The test display makes it easy for anyone to use or configure the controller. If a user scrolls to a parameter and waits for a few seconds, the test display begins scrolling in marquee fashion. The controller then displays a description of that parameter in plain English (Spanish, French German languages also available).
