Detailed Product Description

The Description of Instrument:

LVPR400 Middle and long way real color non-paper recording instruments can sampling isolated thoroughly, recording and communicating for 40 channels different types of signals, and also can finish the contact output for 30 channels configurated relay and switch output for 12 channels at most.

LVPR400 adopts LINUX operation platform, Chinese Windows frame structure, optimized software processing technique and modularized integral structure make its application more convenient and reliable.

With abundant display interface, the LVPR400 adopts imported 10.4"high brightnrss and real color LCD with resolution 640*480, various display.

With simple but clear operation, LVPR400 adopts absoluted Chinese menu and operation interface, which makes the operation easily for user. The password lock guarantee the safety for the user.

 With large capacity data memory, LVPR400 adopts CF electric hard disc with memory 64M, 40 channels data and long time record for 1680 days (4 second distance). And can save forever after switch off.

With convenient data transfer, the saved data can be transfered to administration PC or PDA safety by inserting another CF memory card, and can analyze and print for the history curve and data by previous data analysis software.

With strong network function, can choose RS-232C communication interface, RS-485 communication interface and ETHERNET interface with a 10M speed, support the remote configuration and data analysis for PC, and also can process the remote inspection administration by MODEM telephone dialing or wireless data transfer.LVPR400 also have driver function, can be connected to the minitype printer to print the current or history data, curve in appointed time. Except to support LD2000 current inspection software from our company, LVPR400 also can support some professional configuration softwares as IFLX, KINGVIEW, MCGS and so on.

With standard outer size, the outer size is 288*288*280mm,Hole 281+1*281+1mm.

The Technic Parameter:

Note:

If the needs temperature and pressure compensationess, input channels for temperature and pressure compensationess each are needed.

Advantages:

1.Adopting the imported 10.4" real color LCD, CCFL backlight, resolution 640*480,high   brightness, no view angle.

2.Saving history data by electric hard disc, and never lose date after switch off, due to the difference of recording distance, can save the data from 7 days to 1680 days.

3.Entirely isolated omnipotent input, and can input several signals at same time, no need change module, but through software configuration only.

4.Wider scale for display about project data, can display 5 digit,-1999~19999

Can configurate with Chinese menu, display project location number, project unit

5.Having several advanced arithmetic, can cumulate, temperature and pressure compensate, heat energy integrate for the flux parameters as water, oil, liquid, commonly gas, steam, natural gas and so on

6.Having super limit alarm display, can indicate the the downmost limit, nether limit, upper limit, uppermost limit for each channel, and also can output through the configurated relay contact

7.Standard COM portsRS-485 & RS-232C, adopting standard and open Modbus communication agreement

8.With 10M ETHERNET standard RJ45 interface

9.With RS-232C seriel minitype printing interface, can print the recording data and curve for any time

10.Adopting new style switch, can work normally with alternating current scale from 85VAC to 265VAC

11.Providing isolated switch output for transmitter for +24VDC,convenient for user

Modularized instrument structure, convenient for user to examine and repair. Metal crust,can be used in bad environment

12.Signal input, entirely isolated omnipotent input. LVPR400 series instruments can allow the direct input for 40 different channels with entirely isolation among channels, the isolated voltage is bigger than 400V

13.Signal output, provide switch sensor with 24VDC, can output for 30 channels configurated relay contact, the contact capacity is 3A,250VACresistance loading. Configurated alarm output for downmost limit, nether limit, upper limit, uppermost limit.

14.Communication and Printing. Communication interface, RS-232CRS-485 & ETHERNET RJ45 with baud rate 1200,2400,9600,57600RS-232C,RS-48510METHERNET). Printing interface, RS-232C is connected to mini-type printer directly.

15.Recording time, recording distance, 1,2,5,10,15,30,60,120,240, can select these nine stages freely. Recording length, 40 records,7 days per 30 thirty records with 4 minutes distance, with 60M hard disc.

16.Accuracy,±0.2%FS.

17.Display,640*480, lattice, high brightness, big screen, w/o view angles, imported 10.4" real color LCD screen, CCEL backlight.

18.Saving, inside electric hard disc can protect the parameter and history data, can save forever after switch off
