Model: rdc485ic
The rdc485ic safely connects RS-232 devices
to 2 or 4-wire RS-485 devices without danger of
ground loops and damaging surges. The data
signals have 2.5kV optical isolation. Internally
isolated DC supply provides 2-port galvanic
isolation, or full 3-port can be ordered so both
the RS-232 and RS-485 signals float with respect
to the power supply ground. Jumpers allow
internal 120Ω terminating resistor.

Isolation, industrial design, small size, DIN rail
mount, user indication, and DC supply make the
rdc485ic a very engineer-friendly device for
your industrial data communication system.
