KH130 is a alarm instrument which h***e high-precision measurement and data acquisition compatible .It apply to measure physical parameters such as temperature, pressure, liquid level, gr***ity, instantaneous flow ,etc.H***e the communication, tran***ission, feed and other auxiliary functi***. Omnipotent input corresponds to kinds of ?tran***ission signal.The output is the most advanced modular structure and the function is flexible.Alarming state can be set as upper limit, lower limit ,top upper limit or bottom lower limit . It use MODBUS communication protocol which is the most common now. The maximum baud rate up to 19200 |

一、Main technology index sampling rate：≤0.5spower voltage:85-240VAC TC cold-junction compensation：interior component or external CU50 compensation power dissipation:<5W couple cut off or rang exceed：display OPEN the use of ***T technology, its design is more concise and lightweight. input types： TC：K、S、E、J、T、B、NRTD：PT100、CU50、CU100 linear voltage：0-5V、1-5V linear Current：0-10mA、4-20mA expansion of type: in the retention of the above-mentioned type, permit users to specify require input types. Output types： R1A:Relay output(0.8A normally open)R1B:Relay output(0.8A normally close) R1C:Relay output(0.8A normally open+normally close) R2A:Relay output(3A normally open) R2B:Relay output(3A normally close) R2C:Relay output(3A normally open+normally close) W1:SCR non-contactoutput(100-240VAC/0.2A) G:SSR drive voltage(DC12V/50mA output) K1:single-circuit silicon-controlled over-null trigger K2:two-circuit silicon-controlled over-null trigger I1: Optical isolation Current tran***ission output S1: Optical isolation RS485 communication? S2: Optical isolation RS232 communication U1/U2/U3: 5V/12V/24VDC feed Example：A meter type：KH130-A-R1C-R1A-N-I-AC main machine type：KH130，Bargraph display Alarm instrument dimension：96×96mm ，two relays alarming output input current signal，220VAC power |
