1. SummaryYK-19 series intelligent Channels Measurement instrument is intelligent, high accuracy controller for temperature, pressure or level measurement. When use it to equipped with temperature, pressure or level sensor, we can consist temperature, pressure or level measurement control system for various type and range. provideRS232 or RS485 to communication with computer or PLC。
The instrument has a real-time clock for user get date and time。
2.T echnical specificationsInput signal: Resistance temperature Detector Pt100, Cu50, Cu100,3 wires conncetMeasurement accuracy : 0.2％FS±1 digitAlarm Output: buzzercommunication: isolation RS485, baud 1200～9600bps。
transmit: isolation 4-20mA for the first channel,<250ΩDisplay : double 4 digit LED display.Power suply: 220V AC.Power c onsumption: 2WTemperature: 0～50℃Ambient humidity: <85％RHFront panel dimension : 160mm×80mmInstallation dimension : 152mm×76mm3. OperationKey-press DescriptionPress the KEY to mute the Buzzer.at setting parameters state, press the key return to work state. At workstate, press the key to switch cycle display and static display. While at cycle display state,the bottom LED are display –xx-, at static display。
Press the SET key to enter setting status.，After chang the current parameterat setting parameters state, press ▲key making parameter increase one.and hold the ▲key, value will increase or decrease quickly and release for stop. At static display state, press ▲key will change to next channels value display.at setting parameters state, press▼key making parameter decrease one. and hold the ▼key, value wil decrease quickly and release for stop. At static display state, press the key will change to next channels value display.After power on the display window displays HELO to indicate self-checking is right, displays -HH- indicates input over range or sensor disconnection or short-circuit. Instrument adopts man to machine talk model for input parameter, and use various prompting to indicate what kind of data should input. At the work state, the up LED display measured value,the bottom LED display the number of the corresponding channel.The last two are the date(-Ht-) and time(-Lt-).(1)press the En key, the up display window displays –Cd-,bottom LED will display 800, Only 800 is changed to 808, and then press En key again will make the instrument to access the setup parameter setting status, other value is denied for preventing field operators from set parameters incorrectly by mistake.(2) -LP-: the instrument measuring the number of channels,rang:1~16, Factory default 10.(3)1-Sn：the first channel intput sensor type,Reference the table below,Factory default P100.Rang 0-3,Factory default 1.(5)1-PL: the 1st channel lower range value, only for the first,it is lower range value for the transmitter output too.(6)1-PH: the 1st channel higher range value, only for the first,it is higher range value for the transmitter output too. For example,1-PL=0.0,1-PH=300.0, first channel measured value is150.0,then the output 4-20mA value is 12.0mA.(7)2-Sn：the 2nc channel intput sensor type.……(8)1-HA: the 1st channel ultra-high alarm value.(9)1-LA: the 1st channel ultra-low alarm value.……(10)1-Eo: the 1st channel measured value deviation rectify.ex: actual the 1st value is 30.0, currently display value is 29.2,then the parameter 1-Eo=0.8.Factory default 0.0 (11)2-Eo: the 2nd channel measured value deviation rectify.……(12)Addr:the communication address for computer, rang 01～99。
Factory default 1(13)baud:the communication baud for computer, 1200、2400、4800、9600 four items for choice。
Factory default 9600.(14)-Ht-: Current clock date, rang 1.01~12.31.(15)-Lt-: Current clock time, rang 0:00~23.59.(16)tS—the cycle display interval, unit second, rang 1~9999,Factory default 5After parameter sets are finished, LED will display End and then go to working status.4. Communication specificationsThe instrument has RS485 interface, direct communication with the computer.RS485 standard communication distance 1.5km, Can be connected to multiple devices/ instrument.Data character format is 1 initial bit , 8 data bits, 1 stop bit, no parity bit.The instrument using modbus-rtu standard communication protocols,using 3x or 4x.
