SPX-BE-U-2S-D2: sensorProbeX+ BEB expansion unit 

with 8x sensor ports and 20x I/O dry-contact ports 

sensorProbeX+ (SPX+) is a versatile IP based environmental monitoring system. it supports the connection of up to 16 of AKCP's intelligent sensors, 20x dry contact I/O's, 0-5VDC or 4-20mAmp inputs, control relay outputs and monitor third party devices.

SPX+ is compatible with all AKCP sensors, including the "smart sensors" such as swing handle locks, cabinet thermal maps, LCD display and battery monitoring sensors.

You may monitor multiple SPX+ units from AKCPro Server for centralized monitoring and management of all devices.

sensorProbeX+ Expansion Architecture
You may expand the capacity and capability of your AKCP base-unit environmental monitoring appliance by locally (in the same rack) connecting BEB expansion units, or by connecting EXP devices located up to 1000 feet away.

Every SPX+ comes with both EXP (Expansion) and BEB (Basic Expansion Bus) ports. These expansion ports give users the ability to add functionality to their base sensorProbeX+ (SPX+) environmental monitoring appliance, so the monitoring system can grow with any growing needs.

Basic Expansion Bus (BEB)
BEB expansion is suitable for short distance expansion within the rack. Using a base (master) sensorProbeX+ (SPX+) unit together with SPX+ BEB (Basic Expansion Bus) units, users can increase the number of sensor ports and dry contacts available. Recommended for use over a short distance within the same rack only, BEB expansion units provide a cost effective way to expand a sensorProbeX+ (SPX+) environmental monitoring system. A maximum of 4x BEB units can be connected (daisy-chained) to a single SPX+ base unit. The maximum distance from a base (master) SPX+ unit to the last unit in the BEB expansion chain is 33 feet (10 m).
