Industrial RS-232 Isolation Adapter

The UOTEK UT-211 is an optoelectronic isolator that sits inline between two DB9 serial ports. It draws operating power from the TXD, RTS or DTR lines so no external supply is required. The unit handles asynchronous full-duplex traffic at 300bps-57,600bps while providing 2,500Vrms impulse and 500VDC continuous isolation.

Installers protecting legacy serial links

Engineers who need to break ground loops, suppress surge events or shield equipment from hot-plug transients will fit this directly into existing cabling. Buyers who require isolation for higher-speed field buses or multi-drop networks will need a different converter class. The adapter operates from -40 to 85 Celsius in 5% to 95% humidity without active cooling.

2,500Vrms optoelectronic isolation barrier

This single specification determines whether the device survives the voltage spikes present in the target installation. The barrier is rated for 2,500Vrms impulse and 500VDC continuous potential difference between the two DB9 interfaces.

Questions about this item

What maintenance will the optoelectronic isolation need after years of industrial use?

The solid-state isolator has no user-serviceable parts; the DB9 connectors may require occasional reseating if vibration loosens them.

At what baud rate does the asynchronous full-duplex link hit its ceiling?

The converter tops out at 57,600 bps, so sustained traffic above that rate will be the first bottleneck.

How much heat does the adapter generate when powered from the RS-232 port all day?

It draws only milliamps from TXD, RTS or DTR lines, so heat stays negligible inside the -40 to 85 °C operating range.
