Product Description
Two wire passive programmable 4-20MA loop (four bit LED ) display SY LED1 .Two wire passive converter smart display
 
Features    
Low cost module design ,easy to connected with converter  and instrument &meters by PIM.    
two wire passive working way, Need no other auxiliary  power
High measuring accuracy and four bit display  and reach  ±2  
 Adopt LED display panel, can be fit to surroundings with light or Non-light  
  small size design .Item size :35×22.5mm,thickness:17.5mm    
 Industrial temperature range:-45ºC~80ºC,with high Reliability

Typical application:
 Display status of sensor and converter while working.   
 Measurement ,inspection and remote control on industrial equipment.   
 monitor petroleum, chemical industrial ,E-protection and controlling point for mine. 
 Monitor on temperature, pressure, current, liquid level   
 Collect data from  PLC,DCS system and display.   
 Developing products  related with instrument meters ,medical Medical facilities,industrial control equipment.

        Sunyuan LED1 low cost small size four bit two wire passive intelligent loop LED display  adopt passive input and two wire connect with converter 4-20mA loop by series. It can display analog value from 4-20mA in loop by Decimal number according to setting range linearly and correspondly.SY LED1 adopt two wire passive Working principle and measure current signal with go through loop which is input signal of display.also is power of display. Need  no auxiliary power.So it is easy to connect wire . with Small size,high accuracy and low cost etc advantages. Comparing to traditional  display .There are two keys on Sunyan LED1.The display is controlled by CPU.Zero,Full  scale,Dot,alarm,delay time can be set again,It is flexible and practical ,digital meters adopt LED display panel,Each LED segment is drived by constant current. Brightness is uniform during 4-20mA .It is with reverse,over current protection.It fit to monitor Physical quantity  of temperature, pressure, current  and liquid of industrial site , Petroleum and chemical, Environmental monitoring, The mining industry,In most occasion. It covert temperature, pressure, current, liquid level to 4-20mA then connected with SYLED1 display meters .Then display related number Through related sensor it is convenient for user to Omni-directional control.  

        SY LED1 display measures4-20mA current signal. Do not getting power from 4-20mA loop .Number displayed is not direct current value. and it is Preset value of 4mA and 20mA, and display both related preset value linearly.For example .Set 0 for 4mA,Set 8000 for 20mA,  It will display 2000 while input is 8mA,It will display 4000 while inputing 4mA,.If you set 1000 for 4mA,Setting -1000 for 20mA.LED1 will display 0 while inputing 12mA,It will display while input 16mA, Maximum No. is 9999(four bit),Minimum is -1999.

        SY LED1 is with alarm..with two isolated Two isolated switching .It can display,control and alarm. This feature only can realized  from procedure.two spare PC 452 Optical coupling the pad position Reservate..It will fixed while user need alarm function..Two alarm point is set can be positive or negative alarm direction.  Alarm object for display readings, The last decimal point on LED display panel flashing.  alarm messages through port output signal output can drive optocoupler.
  

SY LED1 dimension: 35.0×22.5×17.5 mm,Adopt retardant plastic shell by PIM.  
Hole size of panel 33.0×20.5  +0.2 mm, Display control meters or internal sensors in Cabinet  and the transmitter signal.
