Function
•
With S&H1-LOAD = HIGH the signal at the input S&H1-IN is switched to the output
S&H1-OUT.
•
With S&H1-LOAD = LOW the output S&H1-OUT is disconnected from the input S&H1-IN and
outputs the value which was last valid.
Saving in the case of mains disconnection:
•
Keep S&H1-LOAD to LOW level when disconnecting the supply voltage (mains, DC bus or
terminal 59).
•
Keep S&H1-LOAD to LOW level when connecting the supply voltage (mains, DC bus or
terminal 59).
