Robust DataComm rdc232ir9-dv-3p-dd Repeater Guia De Especificação

Model: rdc232ir9

Isolated EIA/RS-232 Repeater (9-wire: Txd Rxd
DTR/DSR RTS/CTS CD RI Gnd)

The rdc232ir9 safely connects two RS-232 devices without danger
of ground loops and damaging surges. The RS-232 signals have
2.5kV optical isolation, plus two isolated supplies for full galvanic
isolation. Unlike self-powered isolators that weaken the RS-232
signal and stress your hardware, the rdc232ir9 boosts the signal,
effectively doubling the maximum RS-232 distance and allows
performance up to 115 kbps.
The RS-232 signals are fully isolated, plus over 1 million ohms of
impedance are added to the ground path. This effectively
decouples the signal grounds and prevents surge currents. The
RS-232 uses 9-pin d-shell with computer-style pin configuration.
All standard RS-232 signals are supported. One DTE and one DCE
port make it easy to install and test.
Isolation, industrial design, small size, DIN rail mount, user
indication, and DC supply make the rdc232ir9 a very engineer-
friendly device for your industrial data communication system.

Application Details:

The rdc232ir9 is ideal for use with radio modems or in situations
where you desire maximum future flexibility. Since all 9 standard
signals pass through the isolator, you can support any RS-232 serial
application.
