Wiring Inputs
The Si5580 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 connecting 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 Si5580 inputs to another
Si product from Applied Motion, like the Si-1
and Si-100 indexers, or the Si3540 and 7080i
indexer-drives.
Connecting an Input to a Switch or Relay
Use normally open momentary switch to trigger Si5580 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 Si5580 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 Si5580 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. Maximum current is 20
mA per input.
