Isolated RS232 to RS485 Series - Isolated Serial Converters And Repeaters

Isolated Models 4WSD9OTB and 4WSD25OTB convert RS-232 to RS-422 or RS-485 (2 or 4-wire). 2,000V two-way optical isolation protects devices from power surges, spikes and ground loops in harsh electrical environments.

These in-line converters support distances up to 1,200 m (4000 ft.) and data rates up to 115.2 kbps. Switchable modes support 2-wire RS-485, 4-wire RS-485, and full duplex RS-422. Available with female DB9 or DB25 RS-232 inputs.

Removable terminal blocks for RS-422/485 and external power make wiring easy. Accepts external power from 10-48 VDC.

Model 485OI9TB is a basic, isolated converter. It converts unbalanced, full duplex RS-232 signals to balanced full-duplex (4-wire) RS-422/485 or halfduplex (2-wire) RS-485 signals.

The converter provides 1,500 Volts RMS optical isolation of the data lines and ground (and connected devices) between the RS-232 and RS-422/485 signals. RS-232 port has a female DB9 connector. RS-422/485 port has a 6-position terminal block.

The RS-232 side of the converter draws power from the handshake lines (DTR, RTS). At least one handshake line must be asserted (raised high) to power the RS-232 side.The RS-422/485 side must be powered by an external 12 VDC power supply (sold separately).
