Connection Example 3: When Power for Open Collector Reference is Used
When power for open collec-
tor reference (PL1, PL2,
PL3) is used, connect be-
tween PL1 and PULS, PL2
and SIGN, PL3 and CLR as
follows:
Note The signal logic for open collector output is as follows.
When Tr1 is ON
Equivalent to high level input
When Tr1 is OFF
Equivalent to low level input
