HW-group NB-2xOut

The HW-group NB-2xOut is a compact IoT device for secure remote control of external systems. With two relay outputs, it reliably switches devices such as alarms, signal lights, and safety-critical systems. Operated via Narrowband IoT (NB-IoT), it is ideal for remote sites without LAN or Wi-Fi infrastructure.

Fully integrated with SensDesk and HWg-Cloud, relays can be controlled manually online or automatically in response to triggers from other IoT devices. This makes the NB-2xOut a modern, energy-efficient solution for remote process control and facility management.

Technical Features

• 2 relay outputs (DO, latching, individually switchable)
• NB-IoT connectivity for secure low-power communication
• Alarm reaction based on SensDesk-linked devices
• Datalogger for 250,000+ events, exportable with HWg-PDMS
• Power: long-life battery (up to 3 years) or 5V external PSU
• Metal housing (IP40), wall or DIN-rail mount
• Operating range: –10 °C to +70 °C
• Protocols: NB-Push, CoAP, HTTPS with user authentication

Application Fields

• Data centers – remote switching of alarms, emergency lights
• Industry – control of safety systems, fans, or sirens
• Building automation – integration into smart building access/security
• Telecom – remote peripheral management at base stations
• IoT – intelligent automation with SCADA, cloud, or SensDesk

Integration & Cloud Support

The NB-2xOut belongs to the SensDesk ecosystem, compatible with HWg-cloud.com or SensDesk Technology SaaS. Via SNMP, XML, or SensDesk API, it integrates into SCADA, IoT, and cloud environments such as Microsoft Azure or AWS IoT. Combined with devices like NB-2xIn, inputs can automatically trigger NB-2xOut relay switching.

Control & Notification

• Manual: Web-based control via SensDesk
• Automatic: Triggered by alarms from other devices
• Email & push alerts for up to 5 recipients
• Optional SMS/voice with HWg-SMS-GW3 gateway

Variants

• NB-2xOut: Base unit with 2 relay outputs, battery-powered
• NB-2xOut TSet: Includes Vodafone NB-IoT SIM (3 years), PSU, antenna, and battery

Conclusion

The HW-group NB-2xOut offers a secure, energy-efficient IoT solution for remote relay control. With NB-IoT connectivity, two relays, event logging, and cloud ecosystem integration, it is ideal for IT, telecom, industrial, and building automation scenarios. Its scalability ensures long-term usability in modern IoT infrastructures.
