The inputs are arranged into two clusters (1 kV isolation); each containing two digital
inputs (300 V
DC
max) and a 5 V power source with a common. These inputs can be used
to attain information like breaker position or disturbance information that can be
added to the PQ events/data. The inputs are available on an 8-terminal lockable
connector plug with screw terminals. Each terminal can accommodate conductors
with size up to 2.5mm
