1.Brief Introduction
LU-R***0 blue (LU-R***0 color)
LCD recorders may be 1 to *6 channels input, have outputs of status
control, alarm, sensors power supply etc.
2.Technical parameter
◆ Display
windows : **0×**0 high resolution chart blue-white LCD
◆ Input
accuracy: ± (0.2%F.S*1) digit
◆input type: Standard voltage **5V,
**5V
standard current ***0mA, ***0mA
T.C: K, S, B, T, E, J, Wre**5,
N
RTD: Pt**0, Cu*0, Cu**0
specially input: R, WRe**6, the mV signal,
other
◆output types: Switch output: Relay contact
output (resistance **0VAC/0.8A or **0VAC/3A)
the SSR trigger
(*2V/*0mA)
DC*2V/*0mA
DC*4V/*0mA
DC5V/*0mA
transform output: ***0mA (the load
<**0&branded;)、**5V
***0mA（the load
<***0&branded;）、**5V
Communication connection: RS**2 or
RS**5
storage medium: U disk/**6M, U
disk/**2M
◆Record : *6 pens
without U disk, *3.6 days /pen (1 sceond
interval) ~*5 years /pen (4 minutes interval)
U disk/**6M, **6/4×[*3.6 days /pen (1 sceond
interval) ~*5 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
***0×**4.
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, *0 seconds, *0seconds, then
T=
***0×**4/(1/1*1/5*1/*0*1/*0)=******3 seconds=**4.8
hours=*7.*8days.
(note: the total storage is **6×**4 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 *5VAC***4VAC,
*0Hz±1Hz, power consumption *2W
◆Ambient temperature: ***5
℃
◆ ambient
humidity: ***5%RH
