PiBlock 4 relay outputs

The PiBlock 4REL provides the user with 4 relay outputs, each with a changeover contact .

The relay used has 2 changeover contacts that were connected in parallel. This increases the switching capacity at the connections.
The relays are controlled by an I2C IO expander. I2C addresses in the range from 32 to 39 can be assigned to this expander using plug-in jumpers. This means that up to 7 PiBlocks can be connected to a Raspberry PI. The max. The number of relay outputs thus amounts to 28 outputs. The number of outputs is reduced if different PiBlock modules are used with the IO expander (e.g. PiBlock 8DO).

For more information, please refer to current data sheet.
You can find an example of the control in the programming demo (C) or in the programming demo (Python).
For the first use, take a look at the quickstart guide.
