8 Signal Relays Module
This module has its own microcontroller
The 8SR module (datasheet) is composed by 8 signal relays that can be activated or deactivated manually or jointly with a concrete pulse width that can be changed by the user.
Obviously, it can also be known whether a specific relay is activated or not.
Information about how to program this node using Node-RED can be found here. Otherwise, if you want to develop your own applications using the multilanguage API, please check here for more information.
Functionalities
This module has 3 main functionalities, which are:
- Configure module parameters. In this case, you must define the pulse width for each relay.
- Activate or deactivate one, some or all relays.
- Get the current relays status for one or all of them.
