1) Brief Introcucion

    LU-R2100 blue (LU-R3000 color) LCD recorders may be 1 to 16 channels input,have outputs of status control,alarm,sensors power supply etc.

2) Technical Parameters:

2.1 display windows:320*240 high resolution chart blue-white(color)LCD
2.2 input accuracy:+/-(0.2%F.S+1) digit
2.3 input type:standard voltage:0-5V,1-5V;standard current:0-10mA,4-

20mA;T.C:K,S,B,T,E,J,Wre325,N;RTD:Pt100,Cu50,Cu100;specially input:R,WRe526,the mV signal,other
2.4 output types:
2.4.1 switch output:relay contact output(resistance 250VAC/0.8A or 250VAC/3A)
2.4.2 the SSR trigger (12V/50mA)
2.4.3 DC12V/50mA
2.4.4 DC24V/50mA
2.4.5 DC5V/50mA
2.4.6 transform output:4-20mA(load<650Ω),1-5V;0-10mA(load<1000Ω),0-5V
2.4.7 communication connector:RS232 or RS485
2.4.8 storage medium:U disk/256M,U disk/512M

2.5 record:16 pens
    without U disk,23.6 days/pen(1 second interval) - 15 years/pen(4 minutes interval);
    U disk/256M,256/4*[23.6 days/pen (1 second interval) - 15 years/pen(4 minutes interval)]
2.6 storage time:T=storage capacity/the sum of the reciprocal of each open channel's record interval;when storage data is

empty,the storage capacity also the total storage is 4000*504.
For example:when the storage data is empty,the open channels are 1,3,7,the record interval of every channel is 1 second,5

seconds,10 seconds,20 seconds,then T=4000*504/(1/1+1/5+1/10+1/20)=1493333 seconds=414.8 hours=17.28 days.(note:the total

storage is 976*504 when channels<=8)

2.11 cut off protection time:the data can be stored forever when the electricity is cut off for it adopts FLASH MEMORY, it

can run accurately when cut off if hard clocks is equipped.
2.12 power source:switch power supply 85VAC-264VAC,50HZ+/-1%,power consumption:12W
2.13 ambient temperature:0-45 degree
2.14 ambient humidity:0-85%RH
