Function Description of the Digital Input Module Multisio D2-
4DI-2
The
multisio D2-4DI-2
hardware is equipped with four digital inputs.
The module detects an input as active if the input is shorted out. An open switch is de-
tected as passive.
Ensure that the polarity is correct when you connect the electronic switches.
The four input LEDs indicate the state of the digital inputs and the power LED indicates
whether the power is on or off.
The digital inputs can be used differently, e.g. as state or meter inputs.
The module can be accessed by a master device (
multimax,
multisio xD6
(from D6-
ESBS-5DI6RO1DO) with a module bus, multicomp with a module bus or via computer
with
visual energy
via multisys D2-ESBS-3/multisys D2-BSES-3
) using the
module bus interface. The master device has to configure the module and read out the
data acquired by the module for further processing.
The operating voltage is supplied via the module bus interface.
The module cannot be used on its own.
