Watlow's CPC400 controller now includes the TRU-TUNE+ adaptive control algorithm. This control system improves tuning by automatically optimizing control parameters whenever necessary to keep the system at the target temperature. When a system is well tuned, the product is kept closer to the ideal processing temperature. This improves yield and reduces wasteful scrap and the need for reworking mis-processed material. Also, when the process variable tracks the set point more accurately, the process or equipment spends less time warming up and stabilizing, and is more available and productive, which can save capital and energy costs. The CPC400 with TRU-TUNE+ is the next generation of Watlow's CPC400 technology, and has many potential applications in any industry with control needs. "Control technology keeps improving, making it easier than ever to optimize PID control loops," explains Sean Wilkinson, product manager. "The CPC400 with TRU-TUNE+ adaptive control fine tunes PID control loops and adaptively tunes dynamic systems that otherwise would have to be re-tuned by operators." With the TRU-TUNE+ feature the controller tunes loops more precisely than a typical auto-tune feature or manual tuning procedure. Because it tunes control loops automatically, the new feature reduces the time and effort to commission a process as well. Wilkinson notes, "For people who want to eliminate scrap and other waste but don't have the time or expertise to fine tune PID control, TRU-TUNE+ adaptive control can help." The CPC400 controller provides performance and flexibility in a compact design. It integrates full-featured, closed-loop control with user-written logic. Programmable logic can interact with closed-loop control and operate I/O independently. Optional LOGICPRO programming software is available for users who desire to add logic, but is not required in order to use the CPC400 and TRU-TUNE+(tm) for closed-loop control. Four and eight-loop versions offer complete control solutions for a broad range of applications. Each controller includes Watlow's TRU-TUNE+(tm) adaptive control algorithm, isolated, analog inputs and built-in, serial communications. The SERIES CPC400 controllers are UL(r) and C-UL(r) listed and carry the CE mark. Features and Benefits
