19 Oct 2020


As PickData, we firmly believe in solutions like Node-RED, because those allow you to focus on what really matters, bring our added value to the solutions. We have gone one step further on the integration of eManager and Node-RED creating customized nodes for each of our expansion modules.

Node-RED eMOD eManager Nodes

Below we detail the first three eManager modules with full integration on Node-RED.


8 Signal relays (Datasheet)

eManager’s 8 signal relays module allows to individually manage each relay or to manage all the relays at the same time.

It allows to configure the following features on the Node-RED module:

  1. Set the pulse width for each relay
  2. Activate or deactivate one, some or all the relays
  3. Get the current relays status

10 Digital inputs (Datasheet)

eManager’s 10 digital inputs module allows to individually manage each input or to manage all the inputs at the same time.

It allows to configure the following features on the Node-RED module:

  1. Time to validate a pulse
  2. Get the status for one, some or all the digital inputs
  3. Get the pulse counter for one, some or all the digital inputs
  4. Reset the pulse counters

Furthermore, you will be able to work in polling or event mode. In polling mode, user starts the flow and asks for data when he needs it, while in event mode user configures certain condition when he wants to be notified and it is the module that notifies him when it has been met. Those conditions include an input status change or detecting that a pulse counter limit has been exceeded.

7 Analog inputs and 2 Power relays (Datasheet)

eManager’s 7 analog inputs and 2 power relays module allows to individually manage each input/relay or to manage all the inputs/relays at the same time.

It allows to configure the following features on the Node-RED module:

  1. Configure the analog inputs for current (0-20 mA) or voltage (0-10 V)
  2. Get the current value of one, some or all the analog inputs
  3. Set the pulse width for each relay
  4. Activate or deactivate one, some or all the relays
  5. Get the current relays status

Like the previous model, this module is able to work in polling or event mode. In this case, an event can be triggered when a value is exceeded, an analog variable is in or out of a range, among others combinations.

Combine them to create your IoT application

eManager is more than an IoT controller; eManager is an industrial modular device that allows you to create customized IoT applications in a graphic, fast and simple way.

With eManager and Node-RED you will be able to create an infinity amount of applications, such as relating an analog value to an actuation on a relay, automating an activation of a digital output depending on a pulse counter value, …. You just need to combine digital inputs, analog inputs and relay modules to be able to offer smart solutions perfectly matched with each project needs.

In addition, Node-RED dashboard will allow you to display all the information of your IoT application in real-time.
