RS-232 to RS-485/422 Lightning Converter Adapter Port-Powered RS-232 to RS-485/422 Converter Serial Adapter with Isolation UT-2127

UT-2127 is a port-powered converter with optoelectronic isolation. It complies with RS-232C, RS422, and RS-485 standards; it converts single side RS-232 signal to a balanced differential RS-422 or RS-485 signal. The built-in optoelectronic isolator can provide as high as 2,500Vrm isolated voltage; the fast instant voltage restraint is designed to protect RS-422/RS-485 interface; it adopts advanced TVS (TRANSIENT VOLTAGE SUPPRESSOR) instant voltage restraint; normally, TVS tube is in high impedance state; when both sides of TVS tube suffer from high power impact in a sudden, the voltage restraint will fast lower the impedance from both sides, and absorb in big current; with this, the voltage on both sides are fixed at presupposed value, protects the component of circuit from damage.

• Electrical interface: RS-232 interface is input to DB9 female connector, and RS-422 / RS-485 interface is output terminal. Compatible with EIA/TIA RS-232C/RS-485/RS-422 standard.
• Protection level: RS-232±15KV ESD protection, 600W lightning surge protection for each line of the RS-485 interface, which can effectively suppress lightning and ESD.
• Connection: The converter ensures that it is suitable for all existing communication software and interface hardware without any software modification to the previous working mode based on RS-232.
• Working mode: Asynchronous half duplex or full duplex. Overall dimension: 61x41x21mm. The longest transmission distance is 1200 m.
• Guarantee: Please feel free to contact us for any problems. As a professional manufacturer, the customer service team will wholeheartedly solve the difficulties for you.
