ANB-C NB-IoT Datalogger with 3 Potential-Free Contact Inputs
The ANB-C is a compact and reliable datalogger with three potential-free (dry contact) inputs, designed for recording switch states, pulses, and status signals from various equipment and systems. Thanks to wireless NB-IoT communication and battery power, this model offers a low-maintenance solution for monitoring technical installations, processes, and building functions.
The logger records every change in the connected contacts – for example open/closed, on/off, or alarm active – and automatically transmits this information via the ATAL OnlineSensor platform. This provides 24/7 insight into the status, operation, and reliability of connected systems.
Applications
- Fault and alarm monitoring of refrigeration systems, pumps, fans, or compressors
- Door and hatch status registration in cold rooms, technical areas, or distribution centres
- Detection of fault messages
- Status monitoring of relay contacts, switches, and security signals
- Support for preventive maintenance through insight into switching frequency or operating time
With nationwide NB-IoT coverage, data are transmitted wirelessly and securely, even from hard-to-reach locations. Battery operation and smart data buffering ensure continuous recording, even during temporary network interruptions.
Key advantages
- Three potential-free contact inputs for status signals
- Fully wireless and battery powered – no external power supply or cabling required
- NB-IoT connection for reliable nationwide communication
- Smart memory (40,000 measurements) with data buffering during network interruptions
- Integration with ATAL OnlineSensor for 24/7 monitoring, alarms, and reports
- Compact and robust housing suitable for industrial and HVAC applications
Target group
The ANB-C has been developed for HVAC installers, facility managers, building automation specialists, machine builders, and OEM partners who want to wirelessly record and analyse status and fault signals.
The ANB-C datalogger provides a universal solution for monitoring contact signals – from technical installations to building systems – combining reliability, simplicity, and wireless freedom in a single compact unit.
