Alarm Signal
You can use an external control signal to activate the PLZ-4WH’s alarm. You can also use the
alarm status output to monitor the alarm status (whether or not it is activated).
Alarm input
Apply an external signal to pins 10 and 12 of the
EXT CONT connector.
The alarm is activated by a low level signal.
The alarm input terminals are pulled up to the
internal circuit’s +5 V level by a resistor that is
approximately 10 k
Ω
. The maximum allowable
voltage is 5 V. The logic threshold levels are
CMOS.
Alarm status output
To monitor the alarm status externally,
monitor the output signal across pins 16 and
17 of the EXT CONT connector.
The signal is on when a protection function
(OVP, OCP, OPP, OHP, REV, or UVP) is
activated or when an external alarm is
applied.
