Running Time and Power On Time Over Signal

The inverter outputs the operation time expiration signal and power on time expiration
signal.
To enable this function, assign
terminals.

Required settings
Notes:
• The example circuit for terminal [11] drives a relay
coil. Note the use of a diode to prevent the
negative-going turn-off spike generated by the coil
from damaging the inverter's output transistor.
