Pulse Input S0 to LoRaWAN

Our converter with four S0 inputs for LoRaWAN is designed for reading devices with the pulse outputs - such as electricity meters, water meters along with other measuring devices. It enables the integration of traditional S0 meters into the wireless LoRaWAN network, which facilitates the data collection and analysis at intervals tailored to the user's needs.

Thanks to the option for the local configuration via cable and a remote configuration over the network, our device significantly reduces the total cost of ownership in projects requiring frequent remote readings of S0 meters.

How Does it Work?
NB-IoT connectivity – today, the  Narrowband IoT coverage is available almost everywhere, with a reach even in hard-to-access areas. Additionally, SIM cards can be obtained for as little as 1 EUR per year.
The antenna connector for the wM-Bus reception is designed to minimize losses, ensuring the highest possible reception sensitivity. As a result, we can cover up to 6 floors, depending on the type of building.
The internal NB-IoT antenna provides sufficient coverage and eliminates the need for two external antennas, preventing the possibility of them being swapped during the installation.
Thanks to the standard SMA connector, you can use a cable to extend the antenna from the hard-to-reach places.

Why Choose the ACRIOS Systems Converters?
Cyber Resilience Act
We have a full control over each part of the code in our devices. The hardware we produce can be maintained even many years after installation.
Manufactured in the EU
Our converters are manufactured in the Czech Republic with Czech subcontractors. Each unit undergoes final testing while focusing on the functionality of individual communication interfaces and device power consumption.
Total Cost of Ownership
We pay close attention to the TCO - from using a coulomb counter to obtain an accurate battery life to the pre-configured units delivery with your settings.
Resilience Against Outages
The device stores the pulse count and always sends the last 3 values in case of a network outage. Users can also set threshold alarm values, where a message is sent immediately regardless of the set reading interval to detect the sudden measurement anomalies.
Technical Support
Good technical documentation is the foundation of quick integration. On our Wiki, you'll find integration manuals, communication protocol descriptions and videos explaining the usage.
High Degree of Configurability
Local configuration via the IEC interface with the option of remote configuration or FUOTA over the NB-IoT network.

What Obstacles Might You Encounter?
If you have ever looked for a solution for meters with the pulse outputs - such as the electricity meters or water meters and their connection, you have likely came across the following situations:
Possible Issues:
  • Connecting multiple meters (typically 2 - 3) at a single location
  • Detecting cable interruptions
  • Handling some atypical installations requiring signal sampling for the status evaluation
  • Using an existing pulse converter for the "dry input" or creating a current loop
  • Setting the meter's counter value in the converter, so that this value is also reported over the network
  • Meters that count two tariffs - high and low - on a single output
  • Meters requiring the high sampling frequency
Our Solution

We have addressed all of these challenges. ACRIOS Systems converters can read any meter or device with a pulse output and you can connect up to four devices with our equipment simultaneously. Our products have been tested within the largest LoRaWAN networks in Europe as well as within the isolated systems.

We have experience in building and operating the private LoRaWAN networks, which allows us to ensure the optimal use of values transmitted in a single message through our converters. Our devices can send both current and historical readings for the potential comparison.
