Applications: 8-channel color paperless recorder with fixed point/program segment adopts the control algorithm of differential in advance. The proportional band P, integral time I and derivative time D are mutually independent of each another without affecting each other when being adjusted. The system overshoot can be controlled with strong anti-jamming capability.
It is equipped with 24-channel universal input (able to input by means of configuration: standard voltage, standard current, thermocouple, thermal resistance, frequency, millivolt, etc.). It can be equipped with 8-loop control and 18-channel alarm output or 12-channel analog output, RS232/485 communication interface, Ethernet interface, mini-printer interface, USB interface and SD card socket; it can provide sensor distribution; it owns powerful display function, real-time curve display, real-time control display historical curve retrospection, bar graph display, alarm status display, etc.
