modname=ckeditor
1：MBUSIt's European standard2Line two bus，Mainly used for measuring heat meter and water meter。
2：485Mode can not supply power to the next equipment,The equipment needs to solve the power supply problem separately，MBUSThe main station can provide36VPower supply to the next instrument。
3：This product module，Can provide load current500Ma，Voltage36V，Press each of the slave stations1.5Ma estimation，The number of available slave stations exceeds300。
\
4：Strong anti-interference ability，There will be no interference and unable to receive data。
\
5：Comprehensive protection function。
\
\
PKSome Yang's product defects：
\
1、Using single chip microcomputer for signal conversion，If disturbed, it will crash.(Function light always on)，485Can't receive data，Power off to recover。
\
2、485 A、BNo protection，Meet24VScrap immediately。
\
3、5VOutput not protected，Some users will24VReceive5Vupper，Module scrapped immediately。
\
\
Other manufacturers，What is the intelligent analysis waveform，To make a fool of laymen.，It's just aNE555Reshaping，A few cents chip。
\
It works anyway.。
\
Our products：
\
1、Using special data switching chip，No crash。
\
2、485 A、BFull protection，Random access24V、36V Not bad。
\
3、5VOutput with reverse protection。
\
\
\
Product Brief：
\
1.Hardware transparent transmission，Signal zero delay，Adapt to many home and abroadMBUSequipment，Stable and reliable transmission performance。
\
2.Industrial grade materials，wholeSMTmachining。
\
3.Support parallel use of multiple devices，Greatly improve the carrying capacity。
\
4.Baud rate full range support，No need to set up，Automatic adaptation。
\
5.Module has short circuit protection function，Load short circuit(Current exceeds550mA)，Instantaneous(less than1Millisecond)cut offMBUSpower supply，Overload indicator on，
\
Delay after short circuit troubleshooting2Power will be restored automatically in seconds。Even if the load is always short circuited(Overload indicator always on)，No damage。
\
6.Module comes with5VDC voltage output，Power supply capability1A，Externally available5VEquipment power supply。
\
\
technical parameter：
\
1、power supply：Direct12-24V(Measured9V-30VStable operation of power supply)
\
2、Serial port mode：RS485Interface,Baud rate300BPS-9600BPS
\
3、Indicator light：Power supply indicator On power on
\
485Data indicator Received485Data lighting
\
MODBUSData indicator ReceivedMODBUSData lighting
\
Overload indicator cut offMBUSOn when powered
\
4、Load capacity：500mAload current，exceed300Slave station。Threshold current triggering short circuit protection mechanism550mA。
\
5、Outline size：115mm*70*25 DIN-Rail Mounting
\
6、working temperature：-10--70℃
\
\
\
Measured，power supply24V，Output current507mA，output voltage34.5V，（Because of the inside500mA PTCAnd loss of sampling resistance1.5V）
\
Communication is completely normal。
