5. Input/output Characteristics (optional)
5.1 Status input
PMAC735A-/B-/E- provides 4 or 8 status input channels, which are used to detect state
information such as breaker position signals and isolator position signals.
The DC voltage which product provides is not below 30V. On the site, dry nodes or passive
auxiliary nodes can be connected directly. When external nodes are closed, the corresponding
status input channels will be closed.
4 status input signals
8 status input signals
【
Attention
】
Since there is a power supply available for detection inside the meter, the external nodes cannot
be further connected to any another voltage system. Otherwise, the status input channels will be
burnt down.
