Redundant Power Input：
The design of the redundant power input allows two power supplies to deliver power to the NSM-208GP to increase reliability. Each of the power supplies will have the capacity to run the switch on its own when the other one goes down. The alarm relay can be used to connect with a buzzer to produce an alarm in the case of a power failure. It is recommended to use dual power input if the switch will be used in heavy load applications.
