The PCB product line incorporates modular stand-alone units that are truly independent from other modules in the system. Each module has an on-board control system which allows the unit to function independently. Each module is also able to be linked to other modules in the system by utilising their upline and downline SMEMA communications.

The modules can also be linked to a higher level monitoring or routing system by utilising a host control system. All modules have ESD safe designs and are CE marked.
