Advanced Monitoring Solution for Critical Infrastructures

The sensorProbeX+ SPX8-X20 represents an advanced monitoring solution with 8 intelligent sensor ports and 20 dry contacts. This state-of-the-art SNMP monitoring system was specifically developed for rack mounting in professional environments. The combination of intelligent sensors and Dry Contact inputs enables comprehensive monitoring of environmental conditions as well as integration of external alarm sources and devices.

The system offers full compatibility with the entire range of AKCP sensors while extending monitoring capabilities with 20 configurable dry contacts. These potential-free contacts can be used as inputs for external alarm systems, door sensors, motion detectors, or other security components.

As a member of the proven sensorProbeX+ family, the SPX8-X20 supports all AKCP smartRack sensors. These include innovative solutions such as the Cabinet Thermal Map Sensor for detailed temperature analysis and RFID-based access controls for maximum security.

Revolutionary Monitoring Technology

AKCess Pro has created a groundbreaking monitoring solution with the sensorProbeX+ SPX8-X20 that unifies environmental monitoring and security monitoring in a single device. The modular architecture allows users to tailor their monitoring infrastructure precisely to individual requirements.

The system was designed for maximum flexibility and supports various installation types. In addition to standard 1U rack installation, customers can also opt for 0U mounting or DIN-rail installation. This versatility makes the SPX8-X20 an ideal solution for data centers, telecom rooms, industrial facilities, and other critical environments.

Intelligent Sensor Integration and Dry Contact Functionality

The SPX8-X20 is characterized by its 8 intelligent sensor ports, which allow direct connection to AKCP’s sensor ecosystem. Customers can choose from a wide variety of sensors, including temperature and humidity sensors, airflow sensors, smoke detectors, and water leak sensors. These sensors communicate digitally with the system and provide accurate real-time measurements.

The 20 dry contacts significantly extend monitoring capabilities. These dry contacts can be configured as inputs for external devices or as outputs for control purposes. Typical applications include monitoring door contacts, window switches, motion detectors, fire alarm systems, or industrial control systems. The contacts support various voltage levels and can operate with both 5VDC internal signals and external voltages up to 30V.

Advanced Network Communication

The SPX8-X20’s network connectivity is based on established standards and modern protocols. The system supports SNMP versions 1, 2, and 3 for seamless integration into existing network management systems. HTTPS encryption ensures secure web-based configuration and monitoring.

For modern IoT applications, the system offers MQTT and MQTTS support, enabling seamless integration with cloud-based monitoring platforms. Syslog functionality enables centralized logging of all events and alarms.

The integrated Power over Ethernet (PoE) greatly simplifies installation, as only a single cable is needed for data transfer and power supply. The Fast Ethernet port (10/100 Mbps) ensures reliable network connections even in demanding environments.

Extreme Reliability and Durability

The SPX8-X20 was designed for continuous operation in challenging environments. The system operates reliably in a temperature range of 0°C to 70°C, with special industrial versions capable of handling -25°C to 70°C. The relative humidity can vary between 20% and 80% without affecting system functionality.

With a mean time between failures (MTBF) of over 10 million hours, the SPX8-X20 sets new standards in reliability. This extraordinary durability results from the use of high-quality components and a fanless design with only 1 watt power consumption.

The robust aluminum housing offers optimal protection against environmental influences and electromagnetic interference. Each system undergoes a 96-hour burn-in test before delivery to eliminate early failures.

Licensing and Software Features

The SPX8-X20’s licensing system offers flexible extension options for specific requirements. The VPN functionality enables secure tunnel connections to central monitoring systems. Virtual sensors can be licensed in packs of 5, up to a total of 80 virtual sensors.

The Modbus integration allows incorporation of up to 4 external Modbus devices, each with 15 sensors. For enhanced access control, the user database can be expanded from 100 to 500 users. IPv6 support and RADIUS authentication complete the feature set.

Scalable Expansion Options

The SPX8-X20’s expansion architecture supports two different extension methods. The Basic Expansion Bus (BEB) allows connection of up to 2 additional SPX+ units within a total chain length of 18 meters. This solution is ideal for in-rack or in-cabinet expansion.

For longer distances, the RS485 expansion is available, enabling up to 300 meters between units. This configuration supports E-Sensor8 and E-Opto16 expansion units and offers maximum flexibility for sensor placement.

Technical Specifications and Performance Features

The compact dimensions of 427 mm width and 44 mm height allow space-saving installation in standard racks. The low-profile design supports various mounting options, from tool-free 0U rack to DIN-rail installation.

The system can manage up to 150 sensors simultaneously, including expansion and virtual sensors. The access control database supports 100 users by default and can be expanded to 500 users.

Status is indicated by multicolor LEDs for power, network, and sensor status. An integrated buzzer provides audible alarms for critical events.

Applications and Benefits

The SPX8-X20 excels in data centers where both environmental parameters and security aspects must be monitored. The 20 dry contacts enable integration of existing alarm and security systems without complex retrofits.

Telecom facilities benefit from its rugged design and extensive connectivity options. Cellular integration makes the system ideal for remote sites or as a backup communication channel.

Industrial applications take advantage of the dry contact flexibility for monitoring production systems, safety systems, and environmental conditions. Modular expandability ensures a future-proof investment that scales with growing requirements.

The unique combination of intelligent sensor technology, dry contact integration, and modular flexibility makes the sensorProbeX+ SPX8-X20 the optimal solution for demanding monitoring tasks in professional environments. The system provides a cost-effective alternative to complex, separate monitoring systems by integrating all essential functions into a single reliable platform.
