Background & Definitions

Consibio IoT Controller is an industrial IoT Gateway, that offers a secure link between various industrial, analog, and digital signals and Consibio Cloud – An end-to-end platform allowing real-time streaming of sensor data, datalogging, visualization, alarms and automatic control.

The IoT Controller is the physical link between all these cloud-based features and the most used analog, industrial signal standards for sensors and actuators in the field and the plant floor.

How it works: The IoT Controller collects data from various sensors using 4-20mA loops, 0-10V voltage signals or other and streams these to the cloud in real-time. At the same time, the IoT Controller can send control signals to various actuators or 3rd party PLCs based on user-defined rules defined in the cloud.

Power

IO symbol	Description
5V	Backplane 5V DC output referenced to GND. Can be used for medium power small actuators (max. 1A).
24V	Backplane 24V referenced to GND. Can be used to power the device from external power supply or power 24V sensors.
GND	Backplane ground.
iGND	Ground terminal for low power external sensors and actuator signals galvanically isolated from backplane.
i3V3 / i5V	3.3V or 5V power output for sensors (max. 100mA) with respect to iGND.

See the Wiring examples below for how to use the various inputs and outputs in specific setups

Wiring examples

This section will include a series of examples, representing physical setups of an IoT Controller and other equipment.

NOTICE: All images are guidelines on how to properly wire the IoT Controller with other equipment and it must be stated that the specific wiring is important.

Wiring of an IoT Controller is done at your own risk and the warranty doesn’t cover any mistakes related to damage done by wrong wiring.

Powering the device

The device unit can be powered in two ways:

From a stand-alone 24VDC power supply (input: 100-240 VAC) that can be connected to the M12 plugs on the top of the device. These can be bought from Consibio on request.
An external 17-35 VDC power supply wired directly to the internal spring clamp connector.

See the product specifications for information on power usage.
