The Industrial Quad Relay Bricklet is discontinued and is no longer sold. The Industrial Quad Relay Bricklet 2.0 is the recommended replacement.
The Industrial Quad Relay Bricklet can be used to extend Bricks by four galvanically isolated solid state relays. Each channel can switch currents of up to 1.2 Ampere with 30 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.

The Industrial Quad Relay Bricklet has an 8 pole terminal. Please see the picture below for the pinout.
To test a Industrial Quad Relay Bricklet you need to have Brick Daemon and Brick Viewer installed. Brick Daemon acts as a proxy between the USB interface of the Bricks and the API bindings. Brick Viewer connects to Brick Daemon. It helps to figure out basic information about the connected Bricks and Bricklets and allows to test them.
Connect the Industrial Quad Relay Bricklet to a Brick with a Bricklet Cable. For a simple test we will connect a battery and a LED to test the Bricklet (see picture below).
If you connect the Brick to the PC over USB, you should see a new tab named "Industrial Quad Relay Bricklet" in the Brick Viewer after a moment. Select this tab.
If everything went as expected you can switch the LED by changing the output state with the Brick Viewer.
After this test you can go on with writing your own application. See the Programming Interface section for the API of the Industrial Quad Relay Bricklet and examples in different programming languages.
A laser-cut case for the Industrial Quad Relay Bricklet is available.
The assembly is easiest if you follow the following steps:
Below you can see an exploded assembly drawing of the Industrial Quad Relay Bricklet case:
Hint: There is a protective film on both sides of the plates, you have to remove it before assembly.
See Programming Interface for a detailed description.
