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.
