HW-group Poseidon2 3268 Series: Versatile IP Monitoring System for Server Rooms and Industry

The HW-group Poseidon2 3268 Series (consisting of Poseidon2 3268 and Poseidon2 3268 Tset) is an advanced system for remote monitoring and control of sensors and digital inputs/outputs over a network.

Designed for server room monitoring, industrial facilities, and building management, it supports up to 8 1-Wire/1-Wire UNI sensors (e.g., temperature, humidity, voltage) and 4 digital inputs (dry contacts) for detectors such as smoke detectors or door contacts. With 2 digital NO/NC relay outputs and up to 8 virtual digital outputs (VDO) for controlling remote Poseidon2 or Damocles2 devices, it offers flexible M2M solutions.

The Poseidon2 3268 Series sends alarms via email, SMS (via SMS Gateway HWg-SMS-GW3 - sold separately, not included), or SNMP monitoring and stores up to 250,000 measurements in the internal data logger.

The Poseidon2 3268 Tset variant additionally includes a 3 m temperature sensor, a door contact, and a power supply, while the standard version (Poseidon2 3268) is delivered without accessories. With an integrated web server, support for secure M2M protocols (HTTPs, IPv6, SNMPv3, Modbus/TCP, MQTT), and integration into the SensDesk Portal, the series is ideal for IoT monitoring and industrial applications.

Application Areas of the HW-group Poseidon2 3268 Series

The Poseidon2 3268 Series is versatile and ideal for scenarios where precise monitoring and rapid alerting are required:

• Server Rooms and Data Centers: Monitoring of temperature, humidity, dry contacts (e.g., door contacts, smoke detectors), and control of fans or air conditioning via relay outputs.
• Industrial Facilities: Detection of machine failures, power outages, or environmental changes with alerting via SMS or email.
• Building Management: Monitoring of access controls, water detectors, or air conditioning for optimized operating conditions.
• Warehouses and Cold Storage: Long-term monitoring of temperature and humidity in the food or pharmaceutical industry with data export for compliance purposes.
• IoT Monitoring: Integration into IoT platforms for smart cities, building automation, or remote maintenance of systems.

HW-group Poseidon2 3268 Series - Perfect Monitoring

The Poseidon2 3268 Series combines powerful remote monitoring with flexible control and easy integration. Compared to other monitoring systems, it offers support for numerous sensors, secure M2M protocols, and the ability to send alerts via a central SMS gateway (HWg-SMS-GW3) without additional software.

The internal data logger reliably stores measurements, and compatibility with the SensDesk Portal enables user-friendly monitoring via web or mobile app. The Tset variant makes it easy to get started with ready-to-use accessories, while the standard version is suitable for individual configurations. Support for MQTT enables connection to IoT platforms such as MS Azure or AWS IoT, and the HWg-PDMS software facilitates data analysis and export.

The robust design and easy installation make the series ideal for use in demanding environments such as server rooms or industrial facilities. With the ability to control relay outputs locally or remotely (e.g., as an IP thermostat), the Poseidon2 3268 Series offers a cost-effective solution for complex monitoring tasks.

Integration with HW-group Products

The Poseidon2 3268 Series is optimally matched to HW-group devices such as HWg-SMS-GW3, HWg-WLD, or Damocles2. Parameters such as temperature, humidity, smoke, or water leaks can be monitored via 1-Wire/1-Wire UNI sensors or dry contacts. Alarms are sent via email, SMS (via HWg-SMS-GW3), or SNMP trap, with recipients configured in the device or in software such as HWg-Trigger.

The SensDesk Portal (paid) offers a central platform for visualization and management of sensor data, accessible via web or mobile app. The HWg-PDMS software enables analysis and export of data to Excel, while the HWg-SDK makes it easier for developers to integrate into their own applications. For third-party systems such as Nagios, a plugin is available, and MQTT support enables connection to IoT platforms.

Installation and Setup

Installation is simple: The device is connected to the network via an Ethernet cable (10/100 Mbit/s), and power is supplied via a 9–30 V power supply or a screw terminal. Sensors are connected to the RJ11 sockets (up to 8 sensors via daisy-chain or hub), and dry contacts to the digital inputs.

Configuration is done via the web interface by entering the IP address in the browser. Recipients for alarms (email, SMS) are defined in the device or in software such as HWg-Trigger. For SMS alerting, an HWg-SMS-GW3 is required in the LAN.

The HWg-Config software supports initial configuration, and a factory reset is possible within 60 seconds after switching on. For use with the SensDesk Portal, the device must be accessible via a public IP address or VPN.

The HW-group Poseidon2 3268 Series (Poseidon2 3268 and Poseidon2 3268 Tset) is a powerful solution for remote monitoring and control in server rooms, industrial facilities, and building management systems.

With support for up to 8 sensors, 4 dry contacts, and 2 relay outputs, it offers versatile monitoring options. Integration with the SensDesk Portal, SMS gateway (HWg-SMS-GW3), and IoT platforms, as well as robust data logger functionality, make it ideal for server room monitoring and IoT monitoring. The Tset variant makes it easy to get started with accessories, while the standard version offers maximum flexibility. Optimize your monitoring processes with the Poseidon2 3268 Series.
