Product Description

The SWP-LCD Series PID Auto-Tuning Controllers are designed for systems requiring high-precision measurement and control.

This series integrates the advantages of both digital and analog instruments. It can process measurement signals such as temperature, pressure, liquid level, and speed, providing clear and intuitive digital display and control.

I. Main Features

1. Provides one PID control output and one transmission output, applicable to various measurement and control applications.

2. Smooth manual/automatic switching without disturbance; parameters can be modified in either mode.

3. Multiple control output options available: PWM output, SCR trigger output, solid-state relay (SSR) output, and voltage/current output.
