Robust DataComm rdc422ic-dv-3p-cc Converter Guia De Especificação
The rdc422ic safely connects RS-232 devices to
RS-422 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-422 signals float with respect to the power
supply ground. There is an internal 100Ω
terminating resistor.
