A, SWP - LCD series instrument characteristics
SWP - absorbed in today's computer structure on LCD instrument design idea, hardware adopts a new type of microprocessor with flash memory, expands the high-capacity data storage area;Graphical displays by large LCD display board;Framework idea of introducing Chinese WINDOWS software, and using the data compression technology.
1. The multi-function display:
SWP - LCD instrument appearance size is 80 * 160 * 160 mm, with 40 x 70 mm with backlit LCD graphics display board, can be concentrated show Chinese prompt, set parameters, compensation value, measurement data, the calculated results, the engineering unit, alarm status, etc.
2. Convenient operation interface:
Chinese information, prompt the user for parameter setting step by step.
The exact terminology, logo display data engineering meaning.
Rich display, provide the need to display the parameters of the combination.
Light touch panel key for users of various operations.
3. The rapid rate of communication:
Equipped with standard two-way serial communication port, can be up to 28 k PBS rate associated with PC or other devices to exchange information.
4. Can be free to set the input signal (universal input) :
User can according to the instrument according to need Chinese menu prompt to set or change the input signal type, range, small signal excision, flow quantitative control values, etc.
5. Flexible additional features:
Through additional modules and corresponding parameter setting, instrument can provide simulation of analog signal output, printer interface signal output, the dc feeder power output, two-way serial communication standard
The input signal | analogThermal couple: standard thermocouple, K, E, B, S, J, T, We, etcElectrical resistance: the standard thermal resistance -- Pt100, Pt100.1, Cu50, Cu100 far eastone pressure resistance, etcElectricity flow: 0 ~ 10 ma, 4 ~ 20 ma, 0 to 20 ma, etc. - the input impedance of 250 w or lessElectric pressure: 0 ~ 5 v, 1 ~ 5 v, mV -- -- -- -- -- - the input impedance of 250 kw or morePulse quantityWave shape: rectangle or sine waveDegree: greater than 4 vFrequency ratio: 0 ~ 10 KHZ (or according to customer's requirement) |
The output signal | Analog outputDC 0 ~ 10 ma (load resistance of 750 w or less) DC 4 ~ 20 ma (load resistance of 500 w or less)DC 0 ~ 5 v DC (load resistance 250 kw or more) 1 ~ 5 v (load resistance 250 kw or more)Switch outputRelay output - back to the poor, contact: AC 220 v / 3 a DC 24 v / 6 a resistance (load)The communication outputInterface way - standard two-way communication interface RS - 485 serial RS - 232 RS - 422, etcBaud rate - 300 PBS ~ 28.8 KBPS instrument internal set freelyFeed output24 v DC load or less 30 mA |
features | Accuracy of measurementPrecision measurement shows: plus or minus 0.2% FS of plus or minus 1 or 0.5% FS + 1 for wordsFrequency conversion accuracyGenerally better than that of 0.2% plus or minus 1 pulse (LMS)Measuring range- 1999 -- -- -- -- -- - 99999 wordsThe resolution of thePlus or minus 1 wordDisplay modeWith large screen LCD backlit graphical displayControl/alarmBack to the difference upper limit, lower limit output (the user can freely set)Parameter setting. The Chinese menu prompt. The panel light touch button to setThe parameters value forever. When the power is set value password lockProtect the wayCumulative values remain when the power is cut off time is more than five yearsPower supply voltage automatic reset abnormal automatic reset (Watch Dog) |
Using the environment | The environment temperature0 ~ 50 ℃Relative humidity85 rh to avoid strong corrosive gas or lessThe power supply voltageConventional type AC220V + 10-15% (50 hz plus or minus 2 hz)Special type AC90 ~ 260 v - switch power DC24V + 2 v - switching power supplyPower consumption. 6 w or less (AC220V power supply). 6 w or less (AC90 ~ 265 v switching power supply). 6 w or less (DC24V power supply) |
