The world’s best environmental monitoring solution just got better.


Choose from standard configurations or build your own!


The latest generation of sensorProbe devices, in a form factor that allows for 1U, 0U and DIN rail mounting. A low profile design that is economical on cabinet space. SPX+ comes in several standard configurations, or can be customized by choosing from a variety of modules such as dry contact inputs, IO’s, internal modem, and additional sensor ports.

  • Every SPX+ is equipped with Ethernet, Modbus RS485, EXP and BEB communications
  • Compatible with SPX+ EXP and BEB units, expand the capabilities of your device.
  • 1U rackmount brackets, Tool-less 0U mounting or DIN rail mounting options.
  • Virtual Sensors.
  • Notification by SNMP, Email, SMS (requires optional cellular modem), built in buzzer.
  • Compatible with wide range of AKCP Intelligent sensors.
  • Start with base configuration and build up your device with modules you need.

Intelligent Sensors

SPX+ is compatible with all AKCP Intelligent sensors, making it an extremely versatile and cost effective monitoring solution. From the data center, to remote sites, industrial controls it has you covered.

Environmental Monitoring Sensors

Wherever monitoring of environmental conditions is important to your daily operations and health of equipment, deploy sensors to monitor temperature, humidity, airflow and water leaks.

Security Sensors

RFID Access control swing handle cabinet locks, door contacts and motion detectors will keep you in tune with the security situation at your sites down to cabinet level. Control who can access and when with RFID access control, centrally managed and monitored through AKCPro Server.

Power Sensors

AC Voltage detection, DC volt meters, sensor controlled relays and power metering can all be done on the SPX+

Specialized Sensors

Ultrasonic tank level sensors can monitor for liquid levels in fuel tanks, oil storage, chemical tanks and so on. Any tank up to 2 meters in depth can be monitored. Alarms generated when levels drop to critical levels, making sure youc an re-fill with sufficient notice. Other specialized sensors include the keyswitch override, to disable notifications while maintenance work is being performed, and a programmable LCD display.

AKCPro Server (free with the purchase of SPX+)

  • Manage cabinet maps, sensors, access control and other equipment from anywhere in the world.
  • Monitor data center maps and drill down to single cabinets.
  • Automate notifications based on sensor, power or access control sensors status.
  • Notification Wizards : SNMP traps, Email, Popup Messages, SMS, Remote Unlock (and more…)
  • Use custom scripts for complex sensor input or notification outputs.

SPX+ Standard Configurations

SPX+ Modules

The below modules can be added to the standard configurations to build up the device with what you need. For example, if you wish to have 12 sensor ports, you can order an SPX8 and an additional sensor4 module. You can also build your unit using our online configuration tool to check that it fits in 1U or 0U rack mounting. If you exceed 1U then there is the option to continue the configuration on an additional U connected via BEB to the base unit.

sensor4 (S)
Additional sensor ports can be added to the base SPX+ module in blocks of 4. sensor4 modules are compatible with all AKCP intelligent sensors. Build a cost effective monitoring platform, able to monitor multiple cabinets from a single IP address.
Module Code :- S4
Dry contact modules come in several flavors. IO modules, and isolated input only. Use dry contacts for monitoring a variety of third party devices, door contact sensors, digital outputs from UPS, control panels and alarm panels. Use IO dry contacts to actuate responses to inputs.
Module Codes :- D1, D1i, D1iV, D2, D2i, D2iV
Cellular Modem
The cellular data modem module gives the SPX+ ability to communicate over a cellular data network. An external antenna ensures a good signal can be received even if the SPX+ is inside a cabinet. Send SMS alerts directly from the SPX+ device, or connect it to our central monitoring platform, AKCPro Server, via a VPN connection. Cellular modems are available in European and US bands, and in 3G or 4G versions.
Module Codes :- MA, ME, M4A, M4E

Expansion Architecture Every SPX+ comes with both EXP (Expansion) and BEB (Basic Expansion Bus) ports. These expansion ports give you the ability to add functionality to your base device, so your system can grow with your needs.

Basic Expansion Bus (BEB)
BEB is suitable for short distance expansion within your cabinet. Build up your system adding additional SPX+ BEB Remote units. Daisychain the expansion units up to a maximum of 18 meters for the total chain. SPX+ BEB Remote units are cost effective expansion when you place the unit within the same or neighbouring cabinet.

Expansion (EXP)
EXP is used where you need to extend the distance up to 300 meters. SPX+ EXP Remote devices can be daisychained, with a maximum of 300 meters between each unit.

AKCP Rack+ System
SPX+ can be used as the platform for building an intelligent cabinet solution. Select the level of monitoring you need and build your SPX+ to meet the requirements. For single cabinets or simple installations we recommend you checkout the sensorProbe2+
