Poseidon2 3468: Reliable monitoring

Robust Solution for Industrial Monitoring

The Poseidon2 3468 from HW group is a highly advanced monitoring device specifically developed for demanding industrial applications and IT environments. This device provides a reliable solution for monitoring and controlling sensors and digital inputs over a network.

It supports up to eight 1-Wire or 1-Wire UNI sensors, enabling precise measurement of environmental parameters such as temperature, humidity, voltage, current, or light. Additionally, it features four digital inputs that can be connected to detectors for smoke, water leaks, motion, or power failures. This versatility makes the Poseidon2 3468 an indispensable tool for companies looking to protect their critical infrastructures.

Sensor Monitoring and Control

The Poseidon2 3468 stands out for its ability to monitor up to eight sensors simultaneously. These sensors can be connected via two RJ11 ports in a daisy-chain configuration or via a hub.

The supported sensors cover a wide range, including temperature, humidity, light intensity, voltage, and current. This makes the device ideal for applications such as monitoring server rooms, production facilities, or warehouses.

Sensor monitoring is performed in real time, and the collected data is stored in an internal data logger with a capacity of up to 250,000 measurements. This data can be analyzed with the HWg-PDMS software and exported to MS Excel, making it easy to create detailed reports.

Network Monitoring and Communication

The Poseidon2 3468 is equipped with a 10/100 MBit Ethernet interface, enabling seamless integration into existing networks. It supports modern and secure M2M protocols such as SNMPv3, Modbus/TCP, MQTT, HTTPs, IPv6, and XML, simplifying integration into SCADA systems or IoT solutions. Through the SensDesk.com online portal, users can monitor their sensors from anywhere and receive alarms directly on their mobile device via the SensDesk Mobile App for iOS and Android. This network monitoring ensures that you always have an overview of your systems, no matter where you are.

Relay Outputs for Flexible Control

A standout feature of the Poseidon2 3468 is its two digital relay outputs, which can directly switch 230 V / 10 A. These outputs allow control of devices such as air conditioners, fans, or electric door locks, either manually via the integrated web interface or automatically based on sensor values.

For example, the device can function as an IP thermostat or IP hygrostat by activating heating or cooling systems when predefined thresholds are exceeded. Additionally, the Poseidon2 3468 supports up to eight virtual digital outputs, which can communicate with other Poseidon2 or Damocles2 devices on the same network to realize complex control tasks.

Alerting and Notifications

The Poseidon2 3468 offers versatile alerting options to ensure immediate response to critical events. When thresholds are exceeded or status changes occur at the digital inputs, the device sends notifications via email, SNMP trap, or HWg-Push to up to five recipients. SMS notifications are possible via an external HWg-SMS-GW3 gateway on the local network.

An alarm reminder function and periodic email reports ensure that no important events are missed. Users can define conditions such as “Send an email if the door is open for more than 120 seconds,” increasing the flexibility of alerting.

Power Supply and Installation

The Poseidon2 3468 is designed for use in demanding environments and supports various power supply options: 9–30 V DC, -48 V DC (for telco applications), or Power over Ethernet (PoE). An additional screw terminal enables the supply of external sensors such as smoke detectors or motion sensors.

The device is available in a robust plastic or metal housing for DIN rail mounting, making installation in control cabinets or server rooms easy. The compact design (145 x 90 x 45 mm) and CE compliance ensure easy integration into existing infrastructures.

Differences Between Poseidon2 3468 and Poseidon2 3468 TSet

The Poseidon2 3468 is available as a standalone device and provides full functionality for monitoring and control. The Poseidon2 3468 TSet is an evaluation set that, in addition to the base device, includes a power supply, a 3-meter temperature sensor, a manual, and a CD with software. This set is ideal for companies that want to test the device directly without having to purchase additional accessories separately. Both variants offer identical technical specifications, but the TSet makes it easier to get started with monitoring right away.

Application Areas

The Poseidon2 3468 is highly versatile and particularly suitable for:

• Server Room Monitoring: Monitoring temperature, humidity, and access (door contacts) in data centers.
• Industrial Monitoring: Monitoring production facilities, warehouses, or cold chains.
• Telco Applications: Thanks to -48 V DC support, ideal for telecommunications environments.
• Smart Buildings: Integration into building automation systems for controlling heating, air conditioning, or lighting.
• Pharma and Food: Logging storage conditions for HACCP-compliant reports.

Integration and Software Support

The Poseidon2 3468 is compatible with a wide range of software solutions. The HWg-SDK offers programming examples in languages such as C++, C#, PHP, and Java to simplify integration into custom applications.

The HWg-Trigger software enables advanced alarm forwarding, such as SMS notifications or device shutdowns. With the HWg-PDMS software, S0 pulses can be converted into costs per unit of time and exported to Excel. Support for over 50 SNMP and SCADA applications as well as MQTT for IoT solutions makes the Poseidon2 3468 a flexible platform for modern monitoring requirements.

Security Features

Security is a top priority for the Poseidon2 3468. Access to the web interface can be restricted by passwords or IP address ranges. Support for HTTPs and SNMPv3 ensures secure data transmission. These features are especially important for applications in sensitive areas such as data centers or telecommunications.

The Poseidon2 3468 and the TSet are powerful solutions for monitoring and control in industrial and IT environments. With their ability for sensor monitoring, flexible network monitoring, robust relay outputs, and comprehensive alerting options, they provide companies with the tools to reliably protect their infrastructure.

DIN rail mounting and versatile power supply options make installation simple and efficient. Whether in server rooms, production facilities, or smart buildings – the Poseidon2 3468 is the ideal choice for demanding monitoring tasks.
