The modules are tied together using a ribbon cable that carries power, control voltages and logic signals. Additionally high voltage DC jumpers feed 200VDC from the Power Supply Module to the DC striker output modules. | The modules are tied together using a ribbon cable that carries low current power, control voltages and logic signals.
