HW-group Perseus Energy 285 – DIN rail solution for water protection and energy monitoring with LTE backup
HW-group Perseus Energy 285
Water ingress is one of the most critical risks in data centers, boiler rooms, industrial facilities, or logistics centers. Even small leaks can cause short circuits, system outages, and immense follow-up costs. The Perseus Energy 285 from HW-group is a modern remote monitoring solution in DIN-rail format, combining comprehensive water leakage detection with reliable LTE backup connectivity. This ensures protection even during network or power outages.
The device monitors up to 100 external sensors with a total of 1000 variables and supports temperature, humidity, voltage, and current sensors, as well as detectors such as smoke or door contacts. Most importantly, a dedicated WLD input enables the use of water detection cables up to 185 m in length. Even the smallest liquid amounts are detected and immediately reported – via e-mail, SNMP trap, or SMS/voice call through the integrated LTE modem.
Technical Features
- Connectivity: LAN (RJ45, 100BASE-T) and integrated LTE modem for backup
- Sensor ports: 6x RJ11 for 1-Wire UNI sensors (up to 12 sensors), RS-485 Modbus/RTU, 1x M-Bus Master
- WLD port: supports water detection cables up to 185 m in length
- Digital I/Os: 4 digital inputs (DI with S0 pulse counters), 2 digital outputs (DO) for relay control
- Data analysis: Lua scripting, scheduler, virtual sensors, calendar-based automation
- Alerts: e-mail, SNMP trap, SMS/voice alarms via LTE modem
- Security: Radius 802.1X, HTTPS, admin/user accounts, IPv6, SNMP v3
- Data logger: storage of >250,000 readings with export via HWg-PDMS
- Power supply: 230 V with 24 V output for external sensors or relays
Protection Against Water Leakage
The WLD input makes the Perseus 285 an ideal solution for early detection of even the smallest water leaks. Typical scenarios include monitoring raised floors in data centers, condensation from HVAC systems, leaks in pipelines, or pump systems. When liquid is detected, alarms are triggered instantly, and external protection systems such as pumps or sirens can be automatically activated based on the configuration.
Typical Applications
- Data centers & server rooms: leak protection under raised floors, HVAC monitoring
- Boiler rooms & technical facilities: detection of burst pipes, leaks, or flooding
- Pharma & storage: HACCP-compliant monitoring with water protection and temperature logging
- Greenhouses: humidity and irrigation control with early leak detection
- Industrial plants: protection of critical machine rooms with water and energy monitoring
Integration & Analysis
Through open APIs (SNMP, Modbus/TCP, MQTT, XML), the Perseus Energy 285 easily integrates into SCADA and IoT systems. The Meters API further enhances functionality by collecting sensor data from other LAN devices (e.g., STE2 R2, SNMP UPS) for combined analysis. With SensDesk SaaS or On-Premise, users gain access to PDF reports, multi-user support, and alarm escalation. For basic projects, HWg-Cloud.com provides e-mail alerts and simple graphing.
LTE Backup & SMS Gateway
The integrated LTE modem ensures reliable communication even during LAN outages and also serves as an SMS gateway for this device or other HWg devices in the network. This guarantees redundant alarm delivery via SMS or voice call – a crucial advantage for remote locations or unstable networks.
Mobile Monitoring
With the HWg Monitor App (iOS/Android), users can access all values anytime. Water ingress alarms are displayed instantly on smartphones. Widgets provide an intuitive overview of critical parameters directly on the home screen.
Versions
- Perseus Energy 285: base version for flexible configuration, without power adapter or antenna
- Perseus Energy 285 Set: starter kit including quad-band LTE antenna for immediate deployment
Summary
Can the Perseus Energy 285 reliably detect water leaks?
Yes, with the WLD port supporting water detection cables up to 185 m, the device can detect even the smallest amounts of conductive liquid.
How are alarms handled if the LAN connection fails?
Through the integrated LTE modem, alarms continue to be sent via SMS or voice call. The connection to SensDesk remains stable.
Is the Perseus Energy 285 suitable for industrial environments?
Yes, its rugged DIN-rail design, M-Bus/RS-485 integration, and redundant LTE backup make it ideal for industrial, energy, and building technology applications.
