4IOS
Multifunction I/O Module
The module 4IOS has 4 relay outputs with floating switch contacts, over which
control and remote processes can be triggered as well as loudspeaker circuits
distributed.
The module 4IOS provides interfaces as link between the DVS-21 system and the
outside world. It is able to pass DVS-21 internal statuses as floating signals to the
outside world and non-floating signals from the outside world as floating signals to
the DVS-21 system. For this, eight opto-coupler inputs and four relay outputs can
be used.
The 4IOS module has four independent identical sets.

Application example for the 4IOS with PA and intercom systems
The 4IOS module can be used in various applications and includes the following
functions:
1. In PA systems the function “Distribute Loudspeaker Circuit” [LK-
Aufteilung]
In this function the relay output can be monitored with an optocoupler in respect to voice output.
2. In PA and intercom systems the function “Floating Signal or Control
Outputs” [potentialfreie Melde- oder Steuer- Ausgänge]
In the case of transmissions over several systems, the mode of operation, “Secure Transmission” [Gesicherte Übertragung] can be ac-

tivated; this means that an appropriate signal will be outputted when
an error occurs.
3. In PA and intercom systems the function e.g. “Alarm input” [Alar-
meingang]
(also binary coded)
These are configured through available programmes in the firmware ICS or specified modes of operation.

The 4IOS consists essentially of a control unit and the 4 independent sets.
Each set is equipped with a relay and 2 opto-couplers.
The relay makes available a floating switch contact.
