HW-group Poseidon2 3468 – Robust solution for protection against water leakage and water ingress
HW-group Poseidon2 3468
Water leaks and unnoticed ingress can cause immense damages in server rooms, data centers, and industrial facilities – from complete IT outages to production interruptions. The HW-group Poseidon2 3468 is a professional monitoring system developed for critical infrastructures. It combines precise water leakage monitoring, flexible environmental supervision, and smart alarm options in one device.
Up to eight 1-Wire/1-Wire-UNI sensors can be connected directly, including water leak detectors, temperature sensors, humidity sensors, or current and voltage sensors. Additionally, four digital inputs are available for dry contacts – such as smoke detectors, door contacts, or dedicated water alarms. This versatility makes the Poseidon2 3468 ideal for building technology, industrial applications, and IoT environments.
With its built-in data logger for up to 250,000 readings, seamless documentation is guaranteed. Data can be analyzed with HWg-PDMS software and exported to MS Excel – ideal for compliance reports or incident tracking.
Supporting modern communication protocols such as SNMPv3, Modbus/TCP, MQTT, and HTTPS, the Poseidon2 3468 integrates easily into SCADA, IT, or IoT platforms. Through the SensDesk portal or HWg-Cloud, users gain continuous access to sensor data – via web or mobile.
Key Advantages for Water Protection
- Detection of even the smallest liquid amounts: early leak detection with compatible WLD sensors
- Flexible alerting: e-mail, SNMP trap, or SMS via HWg-SMS-GW3 gateway
- Powerful data logger: long-term storage of up to 250,000 values
- Automation-ready: two relay outputs (230 V / 10 A) for HVAC, fans, pumps, or door systems
- Virtual outputs (VDO): linking with other Poseidon2 or Damocles2 devices
- Stable power supply: supports 9–30 V DC, -48 V DC (Telco), or PoE
- Scalability: connect up to 8 sensors and 4 digital inputs
Typical Applications
- Data centers & server rooms: monitoring HVAC systems, raised floors, and access points
- Industrial plants: leak control and machine condition monitoring
- Warehouses & cold storage: prevention of moisture damage to food and pharmaceuticals
- Telecom facilities: reliability in Telco environments with -48 V DC support
- Smart buildings: integration into building automation for heating, cooling, and leakage protection
Safety & Control
With two relay outputs (230 V / 10 A), the Poseidon2 3468 enables direct control actions. It can activate cooling, start pumps, or lock doors automatically when thresholds from water or environmental sensors are exceeded. Extended alarm features – including reminder and escalation options – ensure no alert is missed.
Variants
- Poseidon2 3468: base model with full functionality
- Poseidon2 3468 TSet: includes 3 m temperature sensor, power adapter, software, and manual for immediate use
Installation & Operation
Designed for DIN rail or wall mounting, installation is straightforward. With support for PoE or -48V DC for Telco deployments, the device can be easily installed in control cabinets, server rooms, or production facilities. Developers benefit from SDKs for C++, C#, PHP, or Java, enabling tailored solution development.
Summary
How does the Poseidon2 3468 help protect against water leaks?
It reliably detects liquids using connected WLD sensors or water detectors, triggers alarms, and can immediately activate countermeasures via relay outputs.
How are alarms delivered?
Alarms are sent via e-mail, SNMP trap, or HWg-Push. With an SMS gateway (HWg-SMS-GW3), additional SMS notifications are also possible.
What are the differences between the standard 3468 and TSet versions?
The TSet includes an additional temperature sensor and power adapter, making it ready for immediate use. The standard 3468 version offers maximum flexibility for custom configurations.
