Product Description
Ordering Key
G 3496 0005 is designed as
a cost-effective Plug & Play
solution for interfacing
Dupline
I/O's to control sys-
tems. It performs three func-
tions: Dupline
channel gen-
erator, power supply syn-
chronization (enables 3-wire
system with supply) and
RS232/RS422/RS485 inter-
face.

Mode of Operation
The Dupline
Master Module
is a Dupline
Channel
Generator with the function of
a slave. This means that the
128 Dupline
I/O's can be
read/controlled by a PC/PLC
or a Control board master from
many different suppliers. Up to
16 Dupline
DMM can be con-
nected to the same network
and operate together with
other modules using the same
protocol like operator panels,
MMI's frequency inverters, I/O-
modules etc.
