The process control of 30-segment curve can be realized, and practical functions such as relay action output, 10 sets of limit function and 5 sets of PID call can be realized in 30-segment curve as needed. The complex requirements of curve process control are realized.
The process controller of this program has dual output control functions of heating and cooling, and can also be used as double loop temperature and humidity control functions. The carbon potential control function in the heat treatment application can be realized by the second input oxygen probe sensor.
The second auxiliary input channel has the following functions: heater disconnection alarm function, remote DCS remote setting value SV, humidity sensor input, oxygen probe input carbon potential control function.
The 3 groups of switch and light input can realize flexible switching of various application functions.
This process controller has 29 kinds of commonly used industrial signal sensor input functions.
The control output types are: relay, analog linear signal, solid state relay output (transistor), thyristor (which can directly drive electrical equipment under 5 A).
The program controller has a very convenient man-machine interface design, and the key operation is simple and convenient. The power output indicates the progress bar. When the program curve is executed, it can prompt the current remaining time and the current setting value and so on.
Program curve local edit input is simple and convenient, with power down maintenance function. Alarm on power off function.
Adopt advanced control algorithm to adapt to various operating conditions.
