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?

Two-piece EUROCLAMP connector – an industry-standard two-piece terminal block for quick and secure connections. The advantage of the two-piece terminal block is the ability to prepare the meter connections in advance and then simply attach the terminal block to the PCB.

Support for up to 4 connected devices, providing the maximum flexibility during the installation. This ensures that you won’t need to return for an additional device if there’s one more meter than expected during the installation.

The antenna connector is designed to minimize losses, ensuring the highest possible reception sensitivity. This allows you to use the device inside a heat exchange station while still maintaining a strong signal.

Thanks to the standard SMA connector, you can use a cable to extend the antenna from the hard-to-reach places.

Communication tested within the largest LoRaWAN networks in Europe as well as in the isolated systems.

A big battery with a lifespan of over 10 years, considering the frequency of readings.

IP67 waterproof enclosure for the outdoor installations – ideal for the mounting on the wall of a heat exchange station.

Storing the historical readings and repeatedly sending them in each message to ensure the data recovery even if one or two messages are lost.

The converter, with its wide input tolerance, is compatible with various meters from different manufacturers, ensuring the versatility and an easy integration.

Screws that won't fall out of the cover during installation make the assembly easier and ensure that the IP rating of the converter is not compromised.

For the installations without an electrical power supply, the converter is available in a battery-powered version, ensuring long battery life even with the frequent data readings. For the demanding applications, a version with an external power is available.

Choose ACRIOS Systems converters. Here’s why

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.

From common issues to proven solutions

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:

Typical customer scenarios

Two or three meters are installed at one site, but most converters handle only one.

In a shaft or technical point, there are often multiple meters, such as for cold water, hot water, and heat. Many converters have only one input, which means installing multiple devices, increasing costs and complicating maintenance.

Our solution

Our converter offers up to four pulse inputs, allowing multiple meters to be read from one location using a single device.

This reduces hardware, simplifies installation, and lowers operating costs.

Typical customer scenarios

Cable interruption or contact failure may occur, but standard converters do not detect it.

Pulse lines can be damaged by corrosion, installation work, or vandalism. Standard converters cannot distinguish whether the flow is zero or the cable is broken, which leads to incorrect readings and false values.

Our solution

We detect cable interruption or short circuit and immediately report it.

The technician knows the issue lies in the wiring, not the meter, which saves both time and errors.

Typical customer scenarios

The meter sends multiple tariffs, for example high and low, but the converter captures only one value.

Some meters operate two tariffs on one output, such as by time or direction. Standard converters record only the total, losing important data.

Our solution

We can distinguish and separately count multiple tariffs or states on a single input.

The customer receives accurate data, including separation by mode, such as high/low tariff or forward/reverse direction.

Typical customer scenarios

The initial counter value must be manually aligned with the converter.

If the meter is mid-life, its counter already shows a value, for example 12345. A standard converter starts from zero, resulting in data mismatch and unusable reporting.

Our solution

We allow the initial counter value to be set directly in the converter so that network data correspond to the physical meter.

This prevents inconsistencies even when replacing the meter.
