The first 2000 channels paperless recorder


A recorder with four RS485 communication ports, each communication port can be mounted 254 LU-S Series I / O modules, each LU-S Series I / O Module optional 1-8 channel, the same communication port between the two devices connected to a sampling interval of up to 200mS, and each one I / O module is sampling period of 100mS, precision can reach ± 0.05%, for a communication port 254 under the I / O module, 50 seconds will be able to consult on the time, due to both work independently of each communication port, a recorder 60 seconds will be able to poll 2000 channels.
 

The first store 10 years of continuous paperless recorder


Insert U disk, to achieve real meaning of the historical data storage, not data dump function, as long as the recorder to detect U disk, the data will be directly stored in the U plate, rather than the logger's internal memory, replacing the artificial sweep of the trouble, the largest support 2GU disc.
U disk storage for the press sector, 512 bytes per sector, each recording data using two bytes of the way, each sector can save 256 data, time records must be occupied by 4 bytes, so Each sector can be kept data on the number of = 256-4 = 252.
Capacity = 1G = 1024M = 1048576K = 1073741824B
Sector = 1073741824B/512 = 2097152 Ge
It can record data number = 2097152 * 252 = 528,482,304
If the recording interval of 1S, then the
Recording time = 528,482,304 * 1 second = 88,080,384 minutes = 146.8 thousand hours = 6116 days = 16.7 years
If the recording interval for the 10S, then the
Recording time = 528,482,304 * 10 seconds = 8,808,038 minutes = 1,468,006 hours = 61,166 days = 167.5 years
If the recording interval of 1 minute, then the
Recording time = 1 minute = 528,482,304 * 8,808,038 hours = 367,001 days = 1005


Board-type structure of the first paperless recorder 


    Recorder of all channels are board-type structure, a logger can be any increase or decrease in the number of channels without Depot modified channel card can be purchased separately, eliminating the need for selection of the number of hours due to leak channel or on-site needs a temporary increase in measuring channel brought trouble, but also reduced the time required for maintenance and spare parts and cost, the largest degree of reduction into the recorder maintenance caused by production problems, save time, save trouble, worry, the cost.
