Data logger with remote transmission (5G ready)

ACS IoT-Solutions - reliable data acquisition
for every measurement task

The self-sufficient measurement and recording of data paired with redundant measurement sets new standards for the security and traceability of your measurement data. Thanks to the system completely developed by ACS, from hardware to software, the highest data security is guaranteed.

Das System ist darauf ausgelegt alle Sensortypen mit den gängigsten Normsignalen und Impulsausgängen auszulesen. Mit der App ACS SmartConnect lässt sich jeder Sensor sicher und einfach in das System integrieren.
Die Alarmmeldungen werden sofort und komplett autonom über SMS, E-Mail oder mittels Push-Nachricht auf das Portal gesandt und verkürzt so die benötigten Reaktionszeiten entscheidend

Thanks to the support of some major users, ACS has been able to develop a complete system that 100% meets the set requirements for safety and ease of use. Thanks to the in-house development of all components, each system can be adapted to your specific requirements at any time.

Redundant data acquisition

Comparing the measurements of 2 different measuring methods increases the plausibility and safety of your measured values.

Individual alerting

The freely configurable alerts via SMS, e-mail or push message increase security and shorten your response time.

Reduction of operating costs

With the installation of redundant measurement, time-consuming manual control measurements on site are no longer necessary and reduce operating costs.

Plug & Play

ACS provides you with a complete solution and makes presettings for you on request.

Everything from a single source

Hardware and software were completely developed and manufactured at ACS. This allows us to make adjustments individually according to your wishes.

No additional costs

You get a complete system, from the sensor to the SIM card. No additional contracts need to be signed and no additional costs are incurred.

An all-round carefree package

With ACS IoT Solutions, no wish remains unfulfilled. Gateway, cloud environment and data transmission - all developed by ACS.

During commissioning, each sensor can be configured exactly according to your requirements. The measurement intervals can be set individually for each sensor. This guarantees correct evaluation of the data according to your specifications - regardless of the type of data transducer. The entire programming, including measuring interval and limit values, is done via the specially developed app ACS SmartConnect via Bluetooth interface. Neither an intervention in the IT structure, nor a download of a configuration software is necessary.

Once the configuration is complete, you can keep an eye on your measuring points at all times and everywhere via the online platform "ACS Portal". Subsequent changes, such as recording speeds or alarm values, can be conveniently made at any time.

If the measured values approach the limits you have set, you will be notified by SMS, e-mail or push message via the ACS Alert app. This keeps you in control at all times and allows you to take the necessary steps in a timely manner.


The self-contained communication system from ACS stands for maximum data security. Of course, customer-specific modifications can be made for you at any time. Contact us for a demonstration of the complete system at your facility!


In addition to the hardware, ACS also develops the complete software solutions. This circumstance allows us to prepare and transmit your data in your desired format.

Monitoring & Reporting

The clearly arranged web portal of ACS offers the possibility to manage all your measuring points centrally. In connection with the autonomously operated data loggers DLF4 / HLF4 it is now very easy to obtain the most accurate measured values even from the most remote locations. The data is automatically transferred to the portal with the highest security standards and can be downloaded in the desired format at any time.

Data backup

The security of your data is our highest priority. All your hardware is protected against unauthorized access. Important parameters can only be adjusted by authorized personnel. Your data is temporarily stored on a secure server of ACS in Germany until it is retrieved. If internal security procedures do not allow the data to be run through the ACS portal, please contact us. We will find a suitable solution for you.


We offer sophisticated, individualized alarm management with different escalation levels and modern alerting methods via ACS Alert App, SMS, email, etc.. This gives you the opportunity to react to changes in the situation on site at an early stage.

Our hardware solutions

The right device for every application.

Data logger DLF4

Self-contained data logger with remote data transmission for wall and field mounting

Both analog and digital sensors can be connected via 7 sensor inputs. The input signals range from analog signals such as current, voltage, resistance, via Modbus RTU protocols to digital inputs that can be used as counter or control signals.
