Red Lion adds PID controller capabilities for complete HMI solution

May 4, 2018 – Red Lion Controls is offering additional features for its PXU series of proportional-integral-derivative (PID) controllers, including Ramp/Soak, CT Input, 2nd Analog Input and 2nd Analog Output.

The company says 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.
Production engineers and machine builders can select from a range of controllers with varying capabilities and in three sizes: 1/16, 1/8 and 1/4 DIN models. According to Red Lion, the additional features allow customers to use one source for their process control needs. For example, for processes requiring different temperatures, the Ramp/Soak capability allows timeline versus 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 in order 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.
