8. Extension modul e
8.1 Function
An extension module is used to expand the number of
programmable inputs and outputs of the GD Connect
12.
The RS485-2 interface of the GD Connect 12 can
connect a maximum of 4 extension modules.
The extension modules are available in two versions
which differ only in terms of their power supply:
Version 1: 230V AC / 50-60Hz
Version 2: 110V AC / 50-60Hz
An extension module adds
8 digital inputs (DI-1..8)
2 digital outputs (DO-1..2)
2 analog inputs (AI-1..2)
to the GD Connect 12.
