FAQ

• How many I/O modules can I connect?
  Up to 8 modules per unit, or 110 per SCS with SEC402.
• What happens if one power supply fails?
  The second power supply takes over automatically (dual-redundant).
• Do I need a fan unit?
  Only if ambient temperature exceeds 40 °C.
• Can I mix processor models?
  No, both must be identical (both S2CP471 or both SCP461).
• Is the software license included?
  No, suffix 2 means without Safety Control Function License.

Buying Guide

• Power supply – choose voltage (100-120V, 220-240V, or 24V DC).
• Temperature – select -F model if ambient >40 °C.
• License – verify if you need Safety Control Function License.
• Redundancy – dual processors require 2 identical modules.
• Spare – keep a spare processor module for emergency.

Warranty & Shipping

• Warranty – 12 months against defects.
• Shipping – dispatched within 12-24 hours.
• Carriers – FedEx, UPS, DHL with tracking.
