ControllersIndicators Digital Indicating Controllers DZ2000 Series Digital Indicating Controllers     The DZ2000 series is digital indicating controllerS having a feature to switch two groups of control setpoints by a front key. It can set PID constants, alarm setting, and other various parameters individually to two groups of setpoints. This easy-to-operate digital indicating controller is combined with auto tune and fuzzy logic. Features Easy operation and reliable control Owing to the universal inputs, selectable control outputs, auto tune, fuzzy logic and other features, thiscontroller ensures simplified control and easy operation. The setting of parameters and operation are easy. Dust-proof and water-proof structure conforming to IP65 The front operation panel is constructed to be dust-proof and water-protection to conform to IP65 of IEC standards (IEC529). Two groups of control setpoints Two groups of control setpoints can be set, and PID constants, events, and other various parameters can be set individually to individual setting. Simple program control Program control can be done easily by hold time of two groups of control setpoints and ramp setting (up and down) of the setpoints switching-change time. CE (option) Models complying with CE are available.
