How many inputs and outputs are standard on the AS3?

The AS3 includes the following standard inputs and outputs:

  • Digital Inputs:
    Eight programmable digital inputs (F, R, RES, S1, S2, S3, S4, S5)
  • Relay Outputs:
    • One programmable Form C relay output (FLA/FLB/FLC)
    • Two programmable Form A relay outputs (R1A/R1C, R2A/R2C)
  • Digital Outputs:
    • One programmable open-collector digital output (FP), pulse‑train capable
  • Analog Inputs:
    • Three programmable inputs:
      • II: 4–20 mA
      • RR: 0–10 VDC
      • RX: ±10 VDC
  • Analog Outputs:
    • Two programmable outputs (FM, AM), configurable as 4–20 mA or 0–10 VDC
  • Safety:
    • Embedded Safe Torque Off (STO) safety terminal
