Red Lion Controls has added features to its PXU proportional-integral-derivative (PID) controllers, including Ramp/Soak, CT Input, 2nd Analog Input and 2nd Analog Output. The PXU series is designed to enable tighter, more reliable control over a wide range of processes, including temperature, flow and pressure, from a single model. Users now have the opportunity to select from a range of controllers with varying capabilities and in three sizes (1/16, 1/8 and 1/4 DIN models). Integration with the company’s Crimson enabled hardware provides a complete indication, data acquisition and control solution for virtually any application.
The additional features provide users with one source for process-control needs. For example, for processes requiring different temperatures, the Ramp/Soak capability allows timeline vs. temperature programming for the process that will automatically be run by the PXU. With CT input, high current signals can be transferred to lower ones to be safely accepted by a PID controller or panel meter. For remote changing of a PID controller’s setpoint value, the 2nd Analog Input allows modification from an external device.
