Industrial RS232 to RS485 RS422 Isolated Converter

The UOTEK UT-2016 translates RS-232C signals to RS-422 or RS-485 standards with optoelectronic isolation rated at 2500Vrms and 500VDC continuous. It targets engineers and integrators who must bridge legacy serial equipment to industrial buses in electrically noisy environments.

600W Surge Protection

Each RS-422/485 wire carries a TVS protector rated at 600W for lightning and surge events, while the tiny inter-electrode capacitance preserves high-speed transmission. The converter auto-detects transmit and receive direction without RTS, DTR or jumper settings, delivering plug-and-play operation for both full-duplex RS-422 and half-duplex RS-485 modes.

DB9 and RJ45 Connectors in a Compact Isolated

A DB9 female port accepts the RS-232 host, a DB9 male port serves the RS-422/485 field side, and an RJ45 socket provides an additional wiring option. The isolation barrier and surge clamping protect both ends of the link, making the unit suitable for factory floors, process automation and remote telemetry where ground loops and transient voltages are daily concerns.

Questions about this item

Will the TVS surge protector on the RS-422/485 lines need replacement after repeated 600 W lightning events?

The built-in TVS protector is rated for 600 W per wire and is not a user-serviceable component; if it absorbs a large surge the converter must be replaced.

What limits continuous operation when the converter runs at full RS-485 speed all day?

The 2 500 Vrms optoelectronic isolation barrier and 500 VDC continuous rating define the voltage withstand limit; sustained data throughput is constrained by the RS-485 standard timing.

How much heat or fan noise does the UT-2016 produce inside a closed cabinet?

The unit has no fan and draws minimal power from the RS-232 port, so it generates negligible heat and runs silently in continuous industrial use.
