UTEK UT-2127 Port-Powered RS-232 to RS-485/422 Mini-Size PhotoElectric Isolation

Description

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. This voltage restraint provides 600W each wire with lightning and ESD protection, and surge voltage and instant overvoltage protection on circuit which causing by all reasons; the tiny interelectrode capacitance ensures high speed transmission for RS-422/485 ports. RS-232 port connects with RS-232C standard port by DB9 female connector; RS-422/RS-485 adopts 6 bits terminal block as output. This converter is with built-in zero delay auto receiving and transmitting conversion and unique I/O circuit auto control data flow direction without any handshake signal (RTU, DTR); there is no need jumper wire setting for full duplex (RS-422) and half duplex (RS-485) mode, plug & play. RS-232 side in DB9 female, RS-485/422 side in binding post Max connection: 32 RS485/422 devices; Max distance: 1.2 KM. Baud rate: 300BPS-115.2KBPS; Size:61mm x 41mm x 21mm Environment:-40℃ to 85℃, Relate humidity 5-95% Protection: +/-15KV ESD protection for RS-232 interface Photoelectric isolation voltage: 2.5KVrms /500VDC 600W lightning strike and grounding interference protection for RS-485 .
