As we mentioned in the previous section, the high speed X1 and X2 inputs are designed for
five volt logic. All other digital inputs are designed for operation between 12 and 24 volts DC.
This includes five inputs on the IN/OUT 1 connector and the eight digital inputs on the IN/
OUT 2 connector.
12-24V Single Ended Inputs
The IN/OUT 1 connector includes five single ended, optically isolated input circuits that can
be used with sourcing or sinking signals, 12 to 24 volts. There are six more of these single
ended inputs on the IN/OUT 2 connector. This allows connection to PLCs, sensors, relays
and mechanical switches. Because the input circuits are isolated, they require a source of
power. If you are connecting to a PLC, you should be able to get power from the PLC power
supply. If you are using relays or mechanical switches, you will need a 12-24 V power supply.
This also applies if you are connecting the inputs to the programmable outputs of another Si
product from Applied Motion.
