You can use this Bricklet to switch power supplies, motors, lamps, etc. Consider the maximum voltage and current.
Terminals and contacts are not insulated. If you want to switch higher voltages, consider to put the Dual AC Relay Bricklet in a casing. Touching the contacts is potentially life-threatening!

The following picture shows the different connection possibilities of the Industrial Dual AC Relay Bricklet.
To test a Industrial Dual AC 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 Dual AC Relay Bricklet to a Brick with a Bricklet Cable.
If you connect the Brick to the PC over USB, you should see a new tab named "Industrial Dual AC Relay Bricklet" in the Brick Viewer after a moment. Select this tab. If everything went as expected the Brick Viewer should look as depicted below.
After this test you can go on with writing your own application. See the Programming Interface section for the API of the Industrial Dual AC Relay Bricklet and examples in different programming languages.
Play around with the two relay buttons, an LED indicates the current state of each relay.
A laser-cut case for the Industrial Dual Relay Bricklet and Industrial Dual AC Relay Bricklet is available (images show Industrial Dual Relay Bricklet).
The case of the Industrial Dual AC Relay Bricklet is delivered including cable ties for a cable relief and WAGO connecting clamps to join wires. The case is big enough to accommodate the cable relief as well as the WAGO clamps.
The internal construction can look as follows (with one as well as two relays connected)
The protective conductor (brown) is switched with the Industrial Dual AC Relay Bricklet. The external conductor (green-yellow) and the neutral conductor (blue) are coupled with the WAGO connecting clamps.
It is important that the external conductor is longer then the other cables. This way it is assured that the external conductor will be pulled of at last if the cable relief is overstrained or defect. We recommend the following length for the cables and the stripping:
The assembly is easiest if you follow the following steps:
Never work inside the case when components are carrying voltage!
The exact position of each part can be seen in the following exploded assembly drawing of the Industrial Dual AC Relay Bricklet case:
Hint: There is a protective film on both sides of the plates, you have to remove it before assembly.
