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 opto-
