1. Brief Introduction

 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 parameter

◆      Display windows : 320×240 high resolution chart blue-white LCD

◆      Input accuracy: ± (0.2%F.S+1) digit

◆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

◆output types: Switch output: Relay contact output (resistance 250VAC/0.8A or 250VAC/3A) 

the SSR trigger (12V/50mA)

DC12V/50mA

DC24V/50mA

DC5V/50mA

transform output: 4-20mA (the load <650Ω)、1-5V

                                 0-10mA（the load <1000Ω）、0-5V

Communication connection: RS232 or RS485

storage medium: U disk/256M, U disk/512M

 

◆Record :  16 pens

without U disk, 23.6 days /pen (1 sceond interval) ~15 years /pen (4 minutes interval)

U disk/256M, 256/4×[23.6 days /pen (1 sceond interval) ~15 years /pen (4 minutes interval)]

◆Storage time: T=storage capacity/ the sum of the reciprocal of each open channel’s record interval; when storage data is temple, the storage capacity also the total storage is 4000×504.

            For example: when the storage data is temple, the open channels are 1, 3, 5, 7, the record interval of every channel is 1second, 5seconds, 10 seconds, 20seconds, then

T= 4000×504/(1/1+1/5+1/10+1/20)=1493333 seconds=414.8 hours=17.28days.

(note: the total storage is 976×504 when channels≤8)

◆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.

◆Power source: Switch power supply 85VAC-264VAC, 50Hz±1Hz, power consumption 12W

◆Ambient temperature: 0-45 ℃

◆      ambient humidity: 0-85%RH
