Expert Review

• “This module is reliable for safety tasks. The 2 A per channel is enough for most actuators. The diagnostic alarm saves troubleshooting time. We use it in press and conveyor systems.” – Safety Systems Engineer

Manager’s Insight

• “The F‑DO10x meets high safety levels (SIL3/Cat.4). It simplifies certification for machine builders. The group current limits are clear – plan your load distribution carefully.” – Product Line Manager

Typical Applications

• Emergency stop circuits and safety interlocks.
• Machine guarding (light curtains, safety doors).
• Conveyor systems with fail‑safe stops.
• Process plants requiring SIL‑3 rated outputs.
• Replacement/upgrade for existing safety modules.

Frequently Asked Questions

• Can I use this module with a standard S7‑300 CPU?
  No – it needs a fail‑safe CPU (e.g., 315F‑2DP) and safety software.
• What is the total current per group?
  Horizontal mounting: 10 A (40 °C) / 6 A (60 °C). Vertical: 5 A (40 °C).
• How do I connect the outputs?
  Use a 40‑pin front connector. Each channel has two terminals (L+ and load).
• Is the module hot‑swappable?
  No – power down the rack before removing or inserting.
• What happens if an output shorts?
  The module has short‑circuit protection and will report a diagnostic alarm.

Selection Guide

• Choose this module for SIL3/Cat.4 safety applications.
• If you need fewer outputs, consider F‑DO4x (4‑channel).
• For higher switching frequency, use standard DO modules (non‑safety).
• Always check total group current against your load.
• Verify cable length limits for your installation.
