NOTICE
Unwanted voltage dips
Non-separated electric circuits of the power supplies for
sensor and actuator can lead to unwanted voltage dips
of the sensor supply when switching actuators.
► Fuse the power supplies for sensors and actuators
separately.
► Make sure that the power supply of the device is
sufficiently dimensioned to cover start-up and peak
currents and design the fuse protection concept
accordingly.
For UL: Observe cable requirements and power
supply requirements (see chapter
UL requirements)!
– Establish power supply of sensor/bus and
actuator via a separate power source if possible.
– Due to the galvanic isolation of BNI PNT-538-...,
devices without galvanic isolation such as the
BNI PNT-508-105-Z067 must not be supplied
with the same power
– The total current for the sensor and actuator
supply must not exceed 16 A each.
