Model:KMGK-GL11A type
Active isolation, RS485 has a strong driving ability.
Active type, 9-30V DC wide voltage input, the United States imported ON voltage regulator, ultra low calorific value, the maximum current 40mA.
UseMornsunThe second generationDC-DC isolation module, super stable.Absolutely genuine gold KINGMAX module, the original purchase.
The United States imported eight foot high speed optocoupler Fairchild, super communication rate.
The baud rate adaptive, transparent protocol, connected with and without any setup.
RS232 and 485 both ends have lightning protection, zero damage, zero maintenance.
RS232 and computer can be connected directly, to extend the line selection of male to female (a male and a female) direct type, if you need to extend the line to shoot the connection, after a good shot to contact the seller to modify the freight. Or direct payment, to confirm the return of freight after receiving the goods.
RS232 uses 3 wire system, that is, 2,3,5 feet. 5 feet to the ground, the 232 interface. Not the earth. Can not meet the earth.
Industrial grade optical isolation type interface converter, compatible with RS-232/RS-422/RS-485 standard, the single ended RS-232 signal can be converted to flatDifferential RS-485 signal, built-in optical isolator and DC/DC DC stabilized voltage converter, fastThe transient voltage suppressor (TVS) can effectively inhibit the lightning (LingHEning)And ESD to provide lightning surge protection for each line of 1500W power, can be effectivePrevent lightning and common ground interference. The RS-232 interface is passed through a DB9 header.The connector is connected to the computer serial port.As RS-485 to support the two line half duplex that is RS-485 only two lines thatTo send data to receive data, handshake signals (such as REQUEST RTSTOSEND) usually to control the direction of data transmission,
The optical isolation type interface converter internal circuit can automatically sense the direction of data flow,And automatic switching enable control. Can facilitate the composition of a RS-485 network without any handshake signal, this RS-485 enable controlThe system is completely transparent and does not require a previous RS-232 basedAs a way to make any modification to the software.
Widely used in industryThe automatic control system, access control system, parking system lwop,The automatic bank system, bus fee system, canteen canteen system,Company staff attendance management system, highway toll station system, etc..
