Milo V2.0 provides 24v and 48v DC power via 2 separate PSUs. 24v power is used for the mainboard itself, auxiliary mosfet-controlled circuits, and the emergency stop circuit that triggers the contactor. 48v is only used for the motors.
IMPORTANT: 24v is NOT disconnected when the emergency stop is pressed, so you MUST NOT connect any safety critical systems to the Scylla AUX ports - they may remain powered even when the emergency stop is pressed.
These ports are software-controlled and MUST NOT be relied upon where safety is concerned.
