Wiring Diagram
The figure describes the wiring diagram of the LTs digital outputs.
Terminal Blocks (see page 100).
Standa
rd Input:
(1) When connecting as power surges
Pulse Output/PWM Output/High-speed
Counter (Syn
chronize Output):
NOTE: Q0 and Q1 circuits are push
-pull circuits. The following is the operation of
the push-pull circuit at the Sink Output and the Source Output.
Sink Output: +24(V) is output to termi
nal Q0, Q1 when the logic for Q0, Q1 is off
Source Output: 0(V) is output to terminal Q0, Q1 when the logic for Q0, Q1 is off
Standard Output terminals Q2 or later a
re common open collector outputs. Do not
connect Fast Output terminals Q0, Q1 and Standard Output terminals Q2 or later. It
will short. If you add a manual circuit to terminal Q0, Q1, isolate the manual circuit
and terminal Q0, Q1 with a relay. Without isolation, it will short.
