Description
Product Description
Ziasiot intelligence PID digital pressure controller adopts an advanced expert PID intelligence algorithm, with high control precision, no overshoot, and a fuzzy self-tuning function. The output is designed as modular architecture; you can acquire various control types by replacing different function modules. You can choose PID control output type as any of current, voltage, SSR solid state relay, single / three-phase SCR zero-over triggering and so on. Besides it has other two ways alarm output, and optional transmission output, or standard MODBUS communication interface. The instrument can replace the servo amplifier in driving the valve (valve position control function) directly, external given function, and manual/automatic no-disturbance switch function.
With multiple types of input functions, one instrument can be used with different various input signals, reducing the number of instruments greatly. It has a very good applicability and can be used with multiple types of sensors, and transmitters used in conjunction to achieve the temperature and pressure measurements that, and with all the various actuators on the electrical and electromagnetic heating equipment, electric valves PID regulation and control, alarm control, data acquisition functions.
