Pulse input

Pulse input to IoT converter

The pulse converter, or pulse counter, is one of the most widely used devices due to its versatility. By simple modifications of the LUA script, we can use it for remote readings of the current value, periodic reading of values every X minutes with sending once a day, detection of circuit interruption or for sampling the pulse signal and sending a message depending on the current pattern. 

We supply the converter in several variants, with a D-cell battery, a 2xD-cell battery pack or externally powered for a long service life, even in the most demanding applications.

Communication on the LoRa network via LoRaWAN 1.0.1 or NB-IoT

The external SMA connector allows you to pull the antenna out in installations where it is not possible to operate radio equipment otherwise - for example in sheet metal cabinets.

We offer battery-powered variants for installations where there is no access to power and externally powered variants for long-term operation without worries.

The device lasts up to 10 years on one battery with a sending period of once a month. Consumption when sending a message is 0.067mAh.

The LUA scripting language allows you to adapt the device to a specific project and very quickly implement additional functions that may be needed.

Uncommon long battery life

Although we also offer an economical variant with an AA battery, the most popular converter is the variant with a D-cell battery, which provides a capacity of 17 Ah for the LoRaWAN device and 14 Ah for the NB-IoT version. So you can afford to send messages much more often than you ever need. Together with optimized consumption, we can easily reach a service life of more than 10 years. For extremely demanding applications, we can supply a battery pack with 2xD batteries with a capacity of 34 Ah or externally powered variants with a power supply range of 85 - 305V AC.

Robust design for the most demanding applications

In our designs, we aim for the most robust design that can withstand rough handling. All sensitive components are on the underside of the PCB where there is no risk of damage. SMA connectors are not in the form of a so-called pigtail, but it is a solid piece of metal. We do not buy third-party radio modules, but we design our own solutions. The bushings themselves are sealed with both a rubber seal and a glued thread seal. The printed circuit board is lacquered and on the top side of the board, there are only those components with which the user should interact with. We do everything we can so that our products can be operated in the most demanding applications.

Customization to any application

The converter is used for electricity meter or water meter readings where the output is defined. But more often than not, you need to read a non-standard device or you come across an application that you can't find any product "from the shelf". For these projects, we can prepare a turnkey solution and use a LUA script to modify the device so that it works reliably in a defined application, or make the necessary changes to the hardware itself.

Custom integration service

We also offer customers a custom integration service. It is especially suitable for those who want a complete turnkey solution and do not want to deal with the integration of a specific device/meter. Based on the equipment that needs to be read remotely, we will prepare a solution, including documentation for a specific application.
