Features
--------

* 4 channel digital output
* Output voltages up to 36V
* Galvanically isolated
* Groupable


.. _industrial_digital_out_4_bricklet_description:

Description
-----------

The Industrial Digital Out 4 :ref:`Bricklet <primer_bricklets>` can be used to
extend :ref:`Bricks <primer_bricks>` by four galvanically isolated digital outputs.
The outputs have to be supplied externally with a voltage of up to
36 `Volt <http://en.wikipedia.org/wiki/Volt>`__. 
Output isolation permits the usage without a direct electric connection, 
such that ground loops can be prevented and an additional degree of safety is added.

Typical applications are the interfacing of industrial controllers, such as PLC's or frequency converters,
or the usage in environments were electrical ground levels can not be connected.

If you need more then four outputs, you can add another Industrial Digital Out 4
Bricklet and group these together. If you do this, you have eight outputs which can
set simultaneously in contrast to set both Bricklets successively.
Grouping is only possible for Bricklets connected to one Brick.
Thus you can group up to four Industrial Bricklets on a Master Brick or
two on other Bricks.

|test_connect|.
Additionally connect a voltage source to power the Bricklet and a load
you want to switch. For testing purposes we have connected a battery
and a LED (see picture below).

If everything went as expected you can switch the LED by changing the output
state with the Brick Viewer.
