Industrial Analog Out Bricklet¶

Features¶

• Simultaneous programmable voltage and current output
• Outputs voltage between 0V and 10V (IEC 60381-1)
• Outputs current between 0mA and 24mA (IEC 60381-2)
• No external power supply necessary

Description¶

The Industrial Analog Out Bricklet can be used to extend the features of Bricks by the capability to output voltage and current simultaneous. The voltage can be given in mV and the current in µA. The device is equipped with a 12-bit Digital-to-Analog Converter (DAC).

Connectivity¶

The Industrial Analog Out Bricklet has an 8 pole terminal. Please see the picture below for the pinout.

Test your Industrial Analog Out Bricklet¶

To test a Industrial Analog Out 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 Analog Out 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 Analog Out Bricklet" in the Brick Viewer after a moment. Select this tab. In this tab you can enable and configure the voltage on the VOUT terminal or the current provided by the IOUT terminal. For test purposes, you can measure this voltage with a voltmeter. If everything went as expected the voltage on the voltmeter and the voltage you have configured should be identical.

After this test you can go on with writing your own application. See the Programming Interface section for the API of the Industrial Analog Out Bricklet and examples in different programming languages.

Case¶

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

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 Analog Out Bricklet case:

Hint: There is a protective film on both sides of the plates, you have to remove it before assembly.
