HW-group Perseus Energy 285

The HW-group Perseus Energy 285 is a DIN-rail remote monitoring system built for demanding IT, telecom, industrial, and building automation environments. Combining LAN connectivity with integrated LTE backup, it provides maximum operational reliability and continuous monitoring even during network outages.

Supporting up to 100 sensors and 1000 variables, it integrates multiple sensor types via 6 × RJ11 ports (1-Wire UNI), RS-485 Modbus/RTU, and an M-Bus Master interface. Common parameters include temperature, humidity, voltage, current, and data from energy or utility meters. Its modern protocol support makes it an ideal foundation for energy management, Industry 4.0 projects, and facility supervision.

Technical Highlights

• LAN (RJ45) + integrated LTE modem for redundant communication
• 6 × RJ11 ports (up to 12 1-Wire UNI sensors)
• RS-485 Modbus/RTU and M-Bus Master integration
• 4 digital inputs (DI with S0 counters), 2 digital outputs (DO)
• Automation via Lua scripting, schedules, and virtual sensors
• Alarms by email, SNMP traps, SMS/voice using LTE modem
• Datalogger with 250,000+ values, exportable with HWg-PDMS
• Secure protocols: HTTPS, Radius 802.1X, SNMPv3, IPv6
• Power: 230 V with 24 V sensor/relay output

Dual Connectivity

With dual LAN and LTE connectivity, the Perseus 285 guarantees uninterrupted alerting and data transfer. The LTE modem doubles as an SMS gateway for sending notifications both from the device itself and from other HWg units within the same network.

Automation & IoT

Lua scripting, virtual sensors, and scheduled actions enable custom monitoring workflows. The device can automate external systems such as HVAC, security, or power modules. With open protocols (SNMP, Modbus/TCP, MQTT, XML), it integrates seamlessly with SCADA, IoT, and smart building systems.

Data Integration & Analysis

Meters API allows data aggregation from other LAN devices (e.g., STE2 R2, UPS). SensDesk SaaS or on-premise deployments add alarm escalation, reporting, and graphical data visualization. The included free HWg-cloud offers basic functions for smaller projects.

Logging & Reporting

A built-in datalogger stores over 250,000 events for long-term analysis. With HWg-PDMS, values can be processed in Excel, supporting compliance documentation, audits, and energy reporting.

Applications

• Data centers – monitoring temperature, humidity, and energy
• Industrial plants – energy consumption, process monitoring
• Telecom – redundant LAN/LTE monitoring for critical sites
• Smart buildings – integration into EMS and HVAC control
• Pharma/food – HACCP-compliant condition supervision

Mobile Monitoring

The HWg Monitor app (iOS/Android) provides mobile dashboards with real-time status. Widgets make key alerts and sensor readings instantly visible on the device home screen.

Variants

• Perseus Energy 285: Base model, without PSU or antenna
• Perseus Energy 285 Set: Complete kit including LTE antenna, ready for deployment

Conclusion

The HW-group Perseus Energy 285 delivers a resilient and flexible monitoring platform for energy and environmental applications. With LAN and LTE redundancy, M-Bus and RS-485 integration, advanced alarm management, and automation features, it is a future-proof solution for IT, telecom, industrial, and facility management environments.
