Connecting Signal Cables with Pulse Input Module APM11
The APM11 receives contact ON/OFF, voltage pulse and current pulse. Refer to the figures below
for details on how to connect signal cables since the items to be set by the system generation
builder depend on the input pulse types.
When Receiving No-Voltage Contact Signals (1)
For the relay contacts or transistor contacts, connect as follows.
Pulse input frequency should be 0 to 800 Hz. Max. frequency differs due to the wiring effect, etc.

When Receiving No-Voltage Contact Signals (2)
Carry out connection as follows if a current is needed to flow to the relay contacts or transistor
contacts.
When receiving transistor contact signal of more than 800 Hz frequency, connect as follows.
