9-24V DC RS232 to RS485 RS422 Converter with Isolation , 600W
UT-216 is a 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 1,500W 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 RJ-45 and DB9 male as
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. It is compatible with current
communication software and hardware, no need to set the previous
working mode which base on RS-232.
UT-216 optoelectronic isolated converter provides connection for
point to point, point to multipoint communication. For point to
multipoint mode, each converter is allowed to connect 128 sets
RS-422 or RS-485 devices with baudrate 300-115.2Kbps. The power and
data flow indicators indicate the working status.
