For HXAD HXSP-2118C RS232 To RS485/RS422 Industrial Lightning Protection Photoelectric Isolation 5KM

Description:
This is an industrial-grade optically isolated interface converter, compatible with RS-232/RS-422/RS-485 standards, capable of converting single-ended RS-232 signals into balanced differential RS-422 or RS-485 signals. Built-in optical isolator and DC/DC voltage stabilizer converter can provide 3500V isolation voltage, and the fast transient voltage suppressor (TVS) can effectively suppress lightning (LingHEning) and ESD to provide 600W lightning surge protection per line power can effectively prevent lightning strikes and common ground interference.

The RS-232 interface is connected to computer serial port through a DB9 female connector, and the RS-422/RS-485 end is connected through a DB9 needle or a six-position terminal block with convenient plug-in. Since RS-485 supports two-wire half-duplex, that is to say, RS-485 has only two lines that both send data and receive data. The handshake signal (such as RTS REQUEST TOSEND) usually controls the direction of data transmission. HXADSP-2118C optical The internal circuit of the isolated interface converter can automatically sense the direction of the data flow and automatically switch enable control. An RS-485 network can be easily formed without any handshake signal. This RS-485 enable control is completely transparent and does not require any software modification to the previous RS-232-based working mode.

This optically isolated interface converter can provide reliable connection for point-to-point and point-to-multipoint communication. Point-to-multipoint can allow 32 RS-422 or RS-485 interface devices to be connected. The data communication rate ranges from 300-115. • 2KBPS, three indicator lights indicate the data flow communication situation in time, and the supported communication methods are RS-232 to RS-422/RS-232 to RS-485 conversion.

It is widely used in industrial automation control systems, all-in-one card access control systems, parking lot systems without pay, automatic banking systems, bus toll systems, canteen sales systems, company employee attendance management systems, highway toll gate systems, etc.
