WLKC _series article

WLKC Series Digital PID Controller

Application:Control temperature,humidity,

This series controllers are microprocessor based controllers. Which have been Designed with high accuracy input, various

output  selection, useful options and good reliability at a competitive price.

 

 

     WLKC400          WLKC600           WLKC700         WLKC800         WLKC900

 

High Accuracy:

Input with 14bit A/D resolution, 0.2% accuracy of FS. Built in "Auto Zero-Auto Span" function keep good accuracy.
 
MODBUS Communcation:
series suport both MODBUS RTU and MODBUS ASCII protocal. Communication between controller and HMI or
other equipment is more conveniet (optional function)
 
Autotuning(AT):
AT Function can calculate the optimize PID value for your control system, without trying and error manually.
 
Various Indication Lamps:
Real time monitor the status of output (OUT1/OUT2), AT, alarm (AL1/AL2/AL3), manual output(MAN) and program(PRO)
 
Bar-Graph:
Output percent displayed on the bar-graph in 10 LEDs resolution  (except"WLKC400").
 
Data Lock Function:
All parameters are seperated in 3 operation levels. Each parameter can be hidden or locked to prevent
unauthorized changes.
