Channels on a Single
RS-485 Line
The H1700 Series provides easy
access to digital input and output
signals through an RS-232 or
RS-485 communications link. The
H1750 provides 24 channels of
digital I/O, while the H1770 has
64 channels. For interfacing to realworld signals, the H1700 Series
is designed to work directly with
OMEGA solid state I/O modules.
Modules are available to sense
ac or dc voltages, or to control
ac or dc power lines.
The H1750 mounts directly to
the OMEGA SSS-PC-24V, which
accepts up to 24 I/O modules, while
the H1770 connects to up to four
SSS-PC16-B 16-channel
backplanes.
