Industrial Digital Out 4 Bricklet

Features

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

Description

The Industrial Digital Out 4 Bricklet can be used to extend Bricks by four galvanically isolated digital outputs. The outputs have to be supplied externally with a voltage of up to 36 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 your Industrial Digital Out 4 Bricklet

To test a Industrial Digital Out 4 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 Digital Out 4 Bricklet to a Brick with a Bricklet Cable. 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).

Industrial Digital Out 4 Bricklet setup

If you connect the Brick to the PC over USB, you should see a new tab named "Industrial Digital Out 4 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 Digital Out 4 Bricklet and examples in different programming languages.

Case

A laser-cut case for the Industrial Digital Out 4 Bricklet is available.

Case for Industrial Digital Out 4 Bricklet

The assembly is easiest if you follow the following steps:

  • Screw spacers to the Bricklet,
  • screw bottom plate to bottom spacers,
  • build up side plates,
  • plug side plates into bottom plate and
  • screw top plate to top spacers.

Below you can see an exploded assembly drawing of the Industrial Digital Out 4 Bricklet case:
