HW-group Perseus Energy 240 – Powerful energy and environmental monitoring
HW-group Perseus Energy 240
The HW-group Perseus Energy 240 is a compact, high-performance monitoring gateway designed to integrate RS-485 Modbus/RTU sensors into modern IT and IoT networks. Serving as an intelligent Modbus gateway, it converts Modbus/RTU data into Modbus/TCP, MQTT, or SNMP protocols for seamless integration with SCADA, NMS, and IoT platforms. This makes it ideal for data centers, industrial plants, telecom facilities, and building management.
Supporting up to 100 sensors and 1000 variables, the Perseus Energy 240 provides a scalable foundation for monitoring critical parameters such as temperature, humidity, voltage, and current. With its open architecture, it is equally suited for traditional monitoring and advanced Industry 4.0 scenarios.
Key Features
- RS-485 integration for up to 100 Modbus/RTU sensors (energy & environmental)
- LAN connectivity with protocol conversion: Modbus/RTU → Modbus/TCP, MQTT, SNMP
- Meters API for data aggregation from LAN devices (e.g., STE2 R2, UPS)
- Data logic with Lua scripting, schedules, and virtual sensors
- Datalogger for long-term storage, exportable via HWg-PDMS to Excel
- Secure communication: HTTPS, SNMPv3, Radius (802.1X), IPv6
- Alarms via email, SNMP trap, and optional SMS/voice through gateways
Data Processing & Automation
With Lua scripting, time-based rules, and virtual sensor capabilities, businesses can customize monitoring workflows. Complex energy and environmental data from Modbus sensors can be analyzed, aggregated, and used to trigger precise automated notifications or device actions.
IoT & SCADA Integration
Open protocols such as SNMPv3, Modbus/TCP, MQTT, and XML enable integration into SCADA and IoT ecosystems. The Meters API allows centralization of sensor data from multiple sources, providing enterprise-wide transparency of energy consumption and environmental conditions.
Combined with SensDesk or HWg-cloud.com, users gain cloud-based dashboards, PDF reports, alarm escalation, and multi-user access, making the system suitable for both SMB and enterprise deployments.
Application Areas
- Data centers & server rooms – energy and climate monitoring
- Industrial facilities – voltage, current, and process parameter supervision
- Telecommunications – reliable power/environment control in critical sites
- Building management – integration into energy & smart building platforms
- Pharma & food storage – HACCP-compliant monitoring of conditions
Mobile Monitoring
With the HWg Monitor App (iOS/Android), administrators gain mobile access to data in real time. Widgets display critical sensor metrics on smartphones for immediate issue awareness.
Variants
- Perseus Energy 240: Base model without PSU, for custom applications
- Perseus Energy 240 Set: Complete kit with PSU for quick deployment
Conclusion
The HW-group Perseus Energy 240 is a flexible and reliable monitoring gateway for energy and environmental parameters. With support for up to 100 Modbus sensors, secure networking protocols, extensive alarm and logging features, and SensDesk cloud integration, it ensures centralized, future-proof monitoring for IT, industry, telecom, and facility management.
