WXZJ-PID20A Series Intelligent PID Controller

◆ Simple operation, high versatility, and multifunctional use. Users can configure various input signal types via the keyboard, significantly reducing the need for backup instruments and associated costs.

◆ Advanced PID algorithm enables fast and stable control with multiple control schemes available for selection.

◆ Advanced digital bumpless transfer technology ensures smooth and rapid switching between manual and automatic control.

◆ Software zero and span adjustment eliminates measurement errors caused by temperature drift and time drift, with a display accuracy better than 0.2%FS.

◆ The instrument employs digital filtering technology to identify and suppress low-frequency disturbances and irregular interference sources in the measurement signal, thereby enhancing anti-interference capability.

◆ Output options include: relay contacts, SSR driving level, thyristor zero-crossing and phase-shift pulse contact outputs; analog transmitter output; +24VDC power supply output.
