The ePDU-YX-A outgoing remote signaling module is used to monitor the on/off status of the precision distribution cabinet outgoing circuit and is an AC remote signaling acquisition and processing unit. Remote signal acquisition is an active wet contact, using optoelectronic isolation input, with an input voltage range of 220VAC ± 20%. By using voltage to determine the on/off information of the circuit breaker, there is no need for auxiliary contacts, which reduces monitoring costs. It can complete the collection of 16 or 32 AC remote signals, reflecting on-site switch information. The module adopts a card rail installation, which is convenient for on-site installation, debugging, and maintenance.
