Features
--------

* 4 Channel Solid State Relay
* Switch up to 30V with 1.2A
* Galvanically isolated
* Groupable


.. _industrial_quad_relay_bricklet_description:

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

The Industrial Quad Relay :ref:`Bricklet <primer_bricklets>` can be used to
extend :ref:`Bricks <primer_bricks>` by four galvanically isolated solid state relays.
Each channel can switch currents of up to 1.2 `Ampere <http://en.wikipedia.org/wiki/Ampere>`__
with 30 `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 control, 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 relays, you can add another Industrial Quad Relay
Bricklet and group these together. If you do this, you have eight relays 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 your Industrial Quad Relay Bricklet
-------------------------------------------

|test_intro|

|test_connect|.
For a simple test we will connect a battery and a LED to test the Bricklet
(see picture below).

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