proportional multi-funcatonal digit controller .DDC Controller LU-1266 Illustration Specification * Reading precision:0.1%,01.% * Setting precision:0.5%;0.1% * Power:24VAC.max1A * Analog input:PT1000/N: 1000; 0 10VDC, 4 20MA * Analog output:0 10VDC * Digit input: Switch contact input * Digit output: Relay output, 7A/250VAC * Output and input points :AI*6 DI*4 A0*6 D0*6 Function: * When it is ventilated, it can be programmable. Multi-loop PID controller. It is configurationassembledset by the table software completely. * The function table with LCD lattice Chinese character display. Yellow and green backlight. * Temperaturehumiditydifferential pressureflow rate and air quality is controlled by PP1PID. * Flexible control in temperature and humidity: Winter and summer shift, compensation in temperature setting, two/four way pipe. * Support function: Fresh air is on economically. antifreeze process .wind pressure switch is linkage. input valve is limited. * Ventilated independent programming loop: using function. setting valve id limited. Four PIO parameters is set separately. * Loop output mode: Analoganalog+ digitdigit; Digit output support linear. binary bit, discrete model * Support R5-485 Modbus-RTU communicated agreement .
