PID502 PID Process Controller

Core Performance & Industrial Application

The PID502 is an intelligent digital PID controller for closed-loop process control.

It supports universal signal input including thermocouple, Pt100, 4-20mA and 0-10V analog signals.

It is equipped with PID auto-tune function, which can automatically calculate optimal control parameters for stable regulation.

It has dual LED display for process value and set value, supports relay, SSR and 4-20mA output options.

It can be equipped with RS485 communication for remote parameter setting and data monitoring.

It is widely used for temperature, pressure and flow control in furnace, oven, packaging and chemical equipment.
