Wiring Inputs
The Si3540 input circuits can be used with
sourcing or sinking signals, 5 to 24 volts.
This allows connection to TTL circuits,
PLCs, relays and mechanical switches.
Because the input circuits are isolated, they
require a source of power. If you are con-
necting to a TTL circuit or to a PLC, you
should be able to get power from the PLC or
TTL power supply. If you are using relays or
mechanical switches, you will need a 5-24
power supply. This also applies if you are
connecting the Si3540 inputs to another Si
product from Applied Motion, like the Si-1
and Si-100 indexers or the Si5580, 7080i
and MC8400 indexer-drives.

Use normally open momentary switch to trigger Si3540 using Wait Input instruction.
Use single throw switch for parameter selection using If Input instruction.
Use normally open momentary switch for jogging.

Note: If current is flowing into or out of an Si3540 input, the logic state of that
input is low. If no current is flowing, or the input is not connected, the logic state
is high.
The diagrams on the following pages show how to connect Si3540 inputs to various
devices.
The maximum voltage that can be applied to an input terminal is
24 volts DC. Never apply AC voltage to an input terminal.

Connecting an Input to the Si-1 Motion Output
(Set Si-1 motion signal to “in position”. Si-1 will trigger Si3540 at end of each move).
Connecting a 3540i, Si5580, 7080i or MC8400
(When output closes, Si3540 input goes low).
Connecting an NPN Type Proximity Sensor to an Si3540 input
(When prox sensor activates, Si3540 input goes low).
Connecting a PNP Type Proximity Sensor to an Si3540 input
(When prox sensor activates, Si3540 input goes low).
