This IP-based monitoring solution combines flexibility with ease of use, enabling companies to proactively monitor their IT infrastructure. The system is specifically designed for environments where reliable sensor data acquisition and precise alarm management are crucial.

Main Components of the SPXN+ Unit

System Components:

• 8 intelligent sensor ports for AKCP sensors
• 10 dry contact inputs/outputs
• 2 analog 0–5VDC/4–20mA inputs for third-party sensors
• 2 mini-relays for control tasks
• Integrated Power over Ethernet (PoE) power supply (no power adapter included)
• 10/100 Mbps Ethernet port for network connectivity
• EXP port for Modbus RS485 and expansion modules

Please Note:

There are many different configuration options for this device. If you require a special configuration, please contact us in writing.

The core of the SPXN+ is a robust, aluminum-based construction designed for continuous operation in demanding environments. With only 1 watt power consumption, the system operates extremely energy efficiently and requires no active cooling.

Advanced Monitoring Features

The SPXN+ supports a wide range of monitoring protocols and offers extensive compatibility with modern network infrastructures. The system is fully SNMP V1/2/3 compatible and additionally supports MQTT/MQTTS, HTTPS, encrypted email, and Rsyslog for versatile data transmission.

Protocol Support:

• SNMP V1/2/3 for network management
• MQTT/MQTTS for IoT integration
• HTTPS for secure web access
• Encrypted email notifications
• VPN connectivity for remote access
• Rsyslog for system logging

The intelligent sensor technology of the SPXN+ allows monitoring of a wide range of parameters such as temperature, humidity, airflow, water leaks, door and window contacts, and vibrations. Each sensor can be individually configured to define specific thresholds and alarm criteria.

Scalability and Expansion Options

A key advantage of the SPXN+ is its modular expandability. The system starts with four activated sensor ports and can be expanded to the full capacity of eight sensor ports through software licenses. This flexible licensing allows companies to gradually scale their monitoring infrastructure.

The expansion functionality supports connecting up to four CCU, E-Sensor8, or E-Opto16 expansion units via the Modbus RS485 port. This increases the total capacity to up to 300 online sensors, including virtual sensors and expansion units.

Reliability and MTBF Values

AKCP has placed great emphasis on durability and fault tolerance in the development of the SPXN+. With a Mean Time Between Failure (MTBF) of 1,400,000 hours based on field data from sensorProbe units, the system is an extremely reliable monitoring solution.

High reliability is achieved through several design decisions:

• Surface-mount technology with highly integrated, low-power components
• Aluminum housing instead of plastic
• 96-hour burn-in test during manufacturing
• Operating temperature range of 0°C to 70°C (Industrial option: -25°C to 70°C)

Software and User Interface

The SPXN+ features an intuitive web-based user interface that allows easy configuration and management. The system supports up to 500 users for access control functions (100 users by default, expandable via license).

User Features:

• Web-based configuration via HTTPS
• Email notifications with encryption
• SMS alerts via optional 4G modem
• RADIUS/TACACS authentication (license required)
• Graphical data visualization
• Historical data logging

Optional Modules and Extensions

Available Options:

• 4G Cellular Data Modem (M4E/M4U) – Cellular connectivity for remote sites
• GPS module – Location tracking and time synchronization
• Additional sensor ports – Expandable to 8 full ports
• Advanced dry contact modules – Up to 10 additional inputs/outputs
• Mini-relay extensions – Additional control outputs
• Analog input expansions – More 4–20mA/0–5VDC inputs
• Virtual Sensor Packs – Software-based sensor simulation
• 500-user access control license – Extended user management
• IPv6 support – Modern network protocols
• VPN connectivity – Secure remote connections

Application Areas and Use Cases

The SPXN+ is ideally suited for various monitoring applications:

Data centers: Monitoring of server room temperature, humidity, cooling systems, and security zones. Precise temperature monitoring prevents overheating of critical IT systems.

Industrial facilities: Monitoring of production environments, warehouses, and machine rooms. The robust industrial sensors detect vibrations, pressure, and other production-relevant parameters.

Telecommunications: Monitoring of base stations, network distributors, and outdoor installations. The integrated 4G modem enables communication even during network outages.

Facility management: Monitoring of building technology, HVAC systems, and security systems. The dry contacts can be connected directly to existing alarm systems.
