Standard Digital Inputs
As we mentioned above, the high speed STEP and DIR inputs are configured 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 of all drives (X3-X7) and the eight digital inputs on the IN/OUT 2 connector of -Si and -QE
drives only (inputs IN1-IN8).
Single Ended Inputs
The STAC6 drives include single ended, optically isolated input circuits that can be used with sourcing or
sinking signals, 12 to 24 volts. This includes inputs X3-X7 on the IN/OUT 1 connector and inputs IN1 - IN6
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.
