  • Power requirements
    – 120 VAC or 24 VDC is acceptable for the SCC-1224 single channel units
  • Inputs
    – Single channel units accept a single two-wire edge or bumper system
  • Outputs
    – Single channel units have two safety outputs and one auxiliary output for signaling
  • External Device Monitoring –EDM is provided on all units with a N/C loop between Z1 and Z2
  • Monitored Reset Modes
    – Monitored manual reset mode that requires closure of the reset circuit followed by opening of the circuit is available on all units
    – Automatic reset mode that occurs upon closure of the reset circuit is available on all units
  • Delayed Auxiliary Output – Delayed opening of the auxiliary output for reversal of a door or gate may be selected on all units except SCC1224ND
