Apex systems are powered by 7-30VDC Power Supply or our PVPS24U wall mount that use universal adaptor for worldwide use. Expensive display or power supple boxes are not needed.


There are 5 options to communicate with your Apex: 0-5V Analog Signal,  0-10V Analog Signal, 4-20 MilliAmp Signal, RS-232 (Standard on all Apex devices), and Device Keypad (Standard)

Multiple Apex Units 

Multiple Apex Devices can be linked together with the BB9 Communications Box. This box uses addressable RS-232 to communicate with all Apex units connected. The BB9 connects directly to a computer via USB port.
