sensorProbeX+ variant SPXN+

The Pre-Configured 1U Standard Version of the SPX+ Platform

The AKCP sensorProbe SPXN+ is the pre-configured 1U standard version of the sensorProbeX+ platform, which AKCP markets as “the world’s most advanced sensor monitoring device.” While the freely configurable SPX+ can be modularly assembled according to individual needs via an online tool, the SPXN+ offers a fixed, ready-to-use configuration with 8 active sensor ports, 10 dry contact I/O channels, 2 analog 0-5 VDC inputs and 2 mini relays in a single 1U rack chassis – all modules are already factory-activated, and no individual configuration is required when ordering.

Ready for immediate use: The SPXN+ is powered by default via Power-over-Ethernet and additionally features a Modbus RS485 port as well as a dedicated input for an optional external 4G cellular modem. This allows the device to be operated reliably even at sites without a fixed network connection.

Like the entire sensorProbeX+ family, the SPXN+ is also compatible with the full AKCP sensor portfolio, including modern “Smart Sensors” such as swing-handle locks, thermal map sensors in the cabinet, programmable LCD displays and battery monitoring sensors – and is fully SNMP-compliant according to SNMP v1/v2/v3.

What the SPXN+ Comes With

Unlike the freely configurable SPX+, the SPXN+ has no selectable options – the following equipment is fixed on every SPXN+.

How the SPXN+ is Built

The housing of the SPXN+ follows the low-profile design of the SPX+ family in classic 1U rack mounting with an overall width of 474.6 mm.

Unlock Additional Functions via Software License

On the SPXN+, all 8 sensor ports as well as all 10 dry contacts, both analog inputs and both mini relays are already factory-activated – no additional license is required for this. For some advanced software functions, AKCP additionally uses a license model.

• Virtual sensor packages (VS) of 5 sensors each, up to a maximum of 80 virtual sensors in total
• User authentication via a RADIUS server (license RAD)
• User authentication via a TACACS+ server (license TAC)
• Integration into building automation systems via BACnet (license BAC)

Compatible with the Entire AKCP Sensor Portfolio

The SPXN+ is part of the same sensorProbeX+ ecosystem as the freely configurable SPX+ and can accordingly be combined with any AKCP intelligent sensor.

• Environmental sensors such as temperature, humidity, airflow or air quality
• Power sensors such as contactless current meters or battery condition sensors
• Security sensors such as motion detectors, smoke detectors or vibration sensors
• Smart sensors such as thermal map sensors, RFID swing-handle locks or programmable LCD displays

In total, an SPXN+ including connected EXP units and virtual sensors can manage up to 300 sensors online. Every SPXN+ is already delivered with 10 free virtual sensors; further ones can be licensed in packages of 5 up to a maximum of 80.

Greater Reach via EXP Units

Since the SPXN+ has no BEB port, expansion is exclusively via the EXP port.

• Connection of AKCP EXP expansion units such as E-Sensor8 or E-Opto16
• Distances of up to 300 meters (approx. 1,000 feet) between the units possible
• The EXP port alternatively serves as a Modbus RS485 interface for third-party devices, supporting up to 4 Modbus devices with a total of 15 sensors
• Central management of multiple SPXN+ devices together via the AKCPro Server

Fully SNMP-Capable and Versatilely Integrable

The SPXN+ supports a broad spectrum of protocols for monitoring, notification and remote access.

For access control, the SPXN+ supports a user database with 100 users by default and optionally up to 500 users. Important to know: Via Modbus RS485, a maximum of 60 sensors in total can be managed (virtual sensors and Modbus devices combined), likewise for Modbus TCP/IP.

Developed for Trouble-Free Continuous Operation

AKCP places particular emphasis on longevity throughout the entire SPX+ family – according to their own statements, a result of deliberate design decisions.

• Aluminum housing instead of plastic for additional mechanical robustness
• Operation with only around 1 watt power consumption – no fan, no active cooling required
• Tested in climate chambers for reliable operation at up to 70 °C
• Every device is burned in for 96 hours before shipment to exclude early failures
• Own, self-developed software instead of large open-source projects, in order to be able to fix errors quickly and specifically add functions

According to AKCP, field experience with the SPX+ series shows even higher reliability: with an installed base of around 5,000 devices, there were on average only 4 RMA-required hardware failures per year – calculated, an MTBF of 10,950,000 hours.

Commissioning in Just a Few Minutes

Setting up the SPXN+ is done in a short time without additional software.

1. Mount the device in the rack (1U standard, optionally 0U or DIN rail)
2. Connect the Ethernet cable – power supply is provided by default via PoE
3. Obtain IP address via DHCP or configure fixed IP in the browser
4. Connect AKCP AutoSense sensors to the active sensor ports – automatic detection
5. Optional: Connect Modbus devices via the EXP port or connect external 4G modem to the UART input
6. Optional: Activate additional license functions such as virtual sensors, RADIUS, TACACS or BACnet
7. Optional: Configure alarm rules, users and VPN connection to the AKCPro Server in the web interface

What is Included in the Scope of Delivery

Please check the scope of delivery upon receipt for completeness and report missing or damaged parts immediately to your supplier. A separate power supply is not included, as power supply is provided by default via PoE.
