Wiring Diagram
The figure describes the wiring diagram of the LTs digital outputs.
Terminal Blocks
(see page 100)
.
Standard Input:
(1) When connecting as power surges
Pulse Output/PWM Output/High-speed Counter (Synchronize 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 terminal 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 are 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.
