HW-group Poseidon2 3268 Series

Water leaks and unnoticed ingress pose critical risks in server rooms, data centers, and industrial facilities. Even small amounts of liquid can damage IT systems, cause short circuits, or disrupt production processes. With the HW-group Poseidon2 3268 Series, companies gain a modern, IP-based monitoring solution designed to reliably detect and control water leakage and other environmental parameters.

The series offers extensive integration capabilities for up to 8 sensors (1-Wire/1-Wire UNI) and 4 digital inputs for dry contacts. This allows not only water sensors but also smoke detectors or door contacts to be connected. In addition, the Poseidon2 3268 Series includes 2 relay outputs (NO/NC) and up to 8 virtual digital outputs (VDO) for controlling external devices. With these features, the system is an excellent early warning and control unit for water and infrastructure monitoring.

Alarms are sent in real time via e-mail, SMS (through HWg-SMS-GW3 gateway), SNMP traps, or relay activations. The built-in data logger stores up to 250,000 events, enabling long-term documentation of data such as temperature, humidity, or water ingress for compliance and reporting. The Tset version includes out-of-the-box accessories such as a temperature sensor, door contact, and power supply – ideal for quick deployment.

With support for modern protocols such as SNMPv3, Modbus/TCP, MQTT, HTTPS, and IPv6, the Poseidon2 Series is especially suited for companies requiring secure communication and seamless integration into existing management systems. Through the SensDesk portal, alarms, reports, and real-time values can be centrally managed and accessed on the go.

Technical Advantages of the Poseidon2 3268 Series

• Supports up to 8 sensors (1-Wire/1-Wire UNI) – e.g., temperature, humidity, voltage, current
• 4 digital inputs for dry contacts, e.g., smoke, water, or door detectors
• 2 digital relay outputs (NO/NC) + 8 virtual digital outputs (VDO) for M2M control
• Alerts via e-mail, SMS, SNMP trap, or relay
• Internal data logger for up to 250,000 events
• Protocols: HTTPS, SNMPv1/v3, IPv6, Modbus/TCP, MQTT, XML, HWg-Push
• PoE-supported, compact design for wall or DIN rail mounting
• Integration with over 50 SCADA and SNMP management systems

Protection Against Water Leakage and Ingress

The Poseidon2 3268 Series provides reliable options for water leak detection. Using HW-group sensors such as spot detectors or WLD sensor cables, even the smallest amounts of liquid are detected. Alerts are immediately forwarded to technicians via SMS, e-mail, or voice call in combination with a gateway. This ensures issues such as condensation under air conditioners, pipe leaks in technical areas, or basement flooding are detected and mitigated early.

Typical Applications

• Data centers & server rooms: monitoring of critical infrastructure for humidity, temperature, and access.
• Industrial facilities: detection of malfunctions, machine errors, and fluid leaks.
• Building management: monitoring of water sensors, HVAC systems, and backup power systems.
• Warehouses & cold storage: protection against temperature fluctuations and liquid damage for food or pharmaceutical inventories.
• IoT monitoring: integration into Smart City or Industry 4.0 applications with MQTT and cloud support.

Integration into IT and IoT Structures

The Poseidon2 3268 integrates seamlessly into existing systems. Using SNMPv3 or Modbus/TCP, it can be connected to professional network management or SCADA platforms. The SensDesk portal provides centralized monitoring with alarm management and reporting. Developers benefit from SDK samples (C++, PHP, Java) and open APIs for custom integrations. MQTT support enables direct connectivity to cloud platforms such as Microsoft Azure or AWS IoT.

Variants

• Poseidon2 3268: base version without accessories – ideal for custom configuration.
• Poseidon2 3268 Tset: complete kit including 3 m temperature sensor, door contact, and power adapter.

Can the Poseidon2 3268 Series reliably detect water leaks?

Yes, in combination with HWg-WLD sensors or water detection cables, the system detects even the smallest amounts of conductive liquid and immediately triggers an alarm.

How are alarms delivered?

The Poseidon2 sends notifications via e-mail, SMS (through HWg-SMS-GW3), SNMP trap, or relay actions. Alerts can be forwarded to up to five recipients simultaneously.

What are the differences between the variants?

The standard version comes without accessories, while the Tset version is fully equipped with a sensor, door contact, and power adapter for immediate use.
