Concept drawing of an IoT Connector sending data to Consibio Cloud, visualized through a dashboard on your computer/smart-phone.
Background & Definitions
Consibio IoT Connector is an industrial IoT Gateway, that offers a secure link between various industrial, analog and digital signals used by a plethora of 3rd party sensors and Consibio Cloud – An end-to-end platform allowing real-time streaming of sensor data, datalogging, visualization, alarms and automatic control.
The IoT Connector is the physical link between all these cloud-based features and the most commonly used analog, industrial signal standards for sensors in the field and the plant floor.
How it works: The IoT Connector collects data from various sensors using 4-20mA loops, 0-10V voltage signals or other and streams these to the cloud in real-time.

Wiring and interfacing – Input options
Inside each IoT Connector, two blocks of each 8 spring clamp terminals provides a total of 16 terminals for various I/O possibilities.
Inputs
| IO symbol | Description |
|---|---|
| Vin | 0-10 V voltage input (ref. to iGND) Resolution: 2.5 mV |
| 4-20mA in | 4-20 mA current loop input. Loop return on iGND. Resolution: 6.0 µA |
| DI1 and DI2 | 0-5V or 0-3V3 Discrete digital inputs Thresholds: Low: 1V High: 2,3V (if 3.3V mode) or 3.9 (if 5V mode) |
Outputs
The IoT Connector cannot generate output signals. If that is needed, the Consibio IoT Controller can take all the same inputs but generate various outputs at the same time.
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 in specific setups.
Wiring examples
This section will include a series of examples, representing physical setups of an IoT Connector and other equipment.
NOTICE: All images are guidelines on how to properly wire the IoT Connector with other equipment and it must be stated that the specific wiring is important.
Wiring of an IoT Connector 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.
Daisy-chaining devices
Furthermore, up to 5 IoT Connectors can be daisy-chained via the top M12-plugs and thus be powered from a single power supply:
4-20 mA input – with external or internal loop supply
4-20 mA input – 4-wire setup
