0RQRIORS &RQWURO %ORFN
The 0RQRIORS control block is a WLPHU ZKLFK LV WULJJHUDEOH VWDUWDEOH YLD D FRQWURO LQSXW If a
change of the logic level from TTL-Low to TTL-High arises at the control input ( 3RVLWLYH 6ORSH ) or
the opposite ( 1HJDWLYH 6ORSH ), the level of the output for the +ROG 7LPH is switched.
The level of the output signal depends on the /HYHO IRU +ROG 7LPH setting. If +LJK is selected, the
level is in the untriggered state TTL-Low, and during the hold time TTL-High; if /RZ is selected,
the level is in the untriggered state TTL-High, and changes during the hold time to TTL-Low.
If the 5HWULJJHULQJ option is activated, a new trigger pulse leads to a new start of the hold time; i.
e. if the hold time is greater than the spacing of the trigger pulse, the output remains permanently
set. In this way, it is possible, for example, to monitor a periodically occurring signal.
If 5HWULJJHULQJ is not activated, incoming trigger pulses are ignored during the +ROG 7LPH . The
Monoflop can first be retriggered after expiration of the +ROG 7LPH .
