HW-group Damocles2 2404

Water leakage represents one of the biggest risks in data centers, server rooms, and industrial facilities. Even small amounts of liquid can cause outages and high costs. The Damocles2 2404 from HW-group is a powerful I/O unit with 24 digital inputs, making it ideal for connecting water detectors and providing instant alarm notifications. With its 4 relay outputs, automated emergency actions such as pumps or sirens can be triggered to effectively minimize damage.

Integration with the SensDesk portal and support for secure IoT protocols (HTTPS, IPv6, SNMPv3, MQTT) make the Damocles2 2404 a robust IoT platform for water protection in critical infrastructures.

Water Leakage Protection & Alerts

With its 24 DI inputs, the Damocles2 2404 can connect to water leak detectors or WLD sensors, which instantly report the presence of conductive liquids. Alarms are sent in real time via e-mail, SNMP trap, or optionally via SMS/voice alerts using the HWg-SMS-GW3. This ensures rapid response. Through the 4 relay outputs, external systems such as pumps, backup power, or alarm systems can be automatically activated.

Technical Features

• 24 digital inputs (DI): for dry contacts such as water detectors, smoke sensors, door contacts
• 4 relay outputs (DO): NO/NC, 50 V / 1 A, for controlling external safety systems
• Virtual outputs (VDO): up to 8, box-to-box linking with other HWg devices over LAN
• Data logger: storage of over 250,000 events, analysis via HWg-PDMS with Excel export
• Communication: SNMPv3, MQTT, HTTPS, Modbus/TCP, XML, HWg-Push
• Connectivity: Ethernet interface (RJ45, 10/100 BASE-T)
• Alerts: up to 5 alarms via e-mail, SNMP trap, SMS/voice call through gateway
• Power supply: 9–30 V DC, PoE IEEE 802.3af, or Telco -48 V standard
• Operating temperature: –30 °C to +85 °C
• Metal housing: 100 x 94 x 25 mm, wall or DIN-rail mountable

Typical Applications

• Data centers: early warning against water leaks in raised floors and HVAC areas
• Server rooms: monitoring for moisture ingress or pipe leaks
• Industry & production: leak monitoring in machine rooms or cooling processes
• Building technology: protection of moisture-sensitive areas such as basements and boiler rooms
• IoT integration: use in SCADA or cloud platforms for data-driven water protection

Integration & Remote Monitoring

The SensDesk portal provides a user-friendly interface for data visualization, long-term graphs, and PDF reports. With SCADA integration (via MQTT, SNMP, Modbus/TCP), the solution can be embedded in industrial control systems. Virtual outputs (VDO) enable box-to-box control, allowing water alarms in one device to trigger relays in another device automatically.

Alarm & Control Functions

• E-mail: direct alerts to up to 5 recipients
• SNMP trap: for integration into centralized monitoring systems
• SMS/voice alert: possible via HWg-SMS-GW3 or HWg-Trigger software
• Relay control: activation of pumps, alarms, or sirens

Versions

• Damocles2 2404: base version with 24 inputs and 4 relay outputs
• Damocles2 2404 Set: includes 12 V / 1 A power adapter, installation CD, and documentation

Can the Damocles2 2404 detect water leaks?

Yes, up to 24 DI inputs can be connected to water leak sensors. They immediately report status changes to the monitoring system.

What alarms are available in case of water ingress?

The device automatically sends e-mail notifications and SNMP traps. Using an SMS gateway, SMS or voice call alerts can also be triggered.

What countermeasures can be activated?

The 4 relays feature NO/NC outputs and can trigger external protection systems such as pumps, emergency shutdowns, or audible alarms.
