The system is powered by a DC voltage source between 7V and 36V (polarity protected). The 5V operating voltage of the BeagleBone is generated by the system's main supply. For relay operation, a minimum voltage of 12V is required. The relays can work with voltages up to 250V and 5A.
A continuous current of 2A can be switched per MOSFET. Per channel there is a maximum pulse load of 18A possible, duty cycle <5%, pulse duration <10msec. Standard load capacity of the system is secured to 8A.
Inputs are galvanically isolated by optocouplers, allowing an input voltage range of 5V - 48V.
