Installation & Commissioning
- Mount on S7‑400 rack (U‑bus compatible).
- Supply load voltage L+ (DC) or L1 (AC) separately.
- Per-channel green LED for status indication.
- No external short‑circuit protection – use external fuse.
- Parallel outputs for redundant load control (same voltage group).
- Diagnostics not integrated, but status LEDs simplify troubleshooting.
Compatibility & Certifications
- Compatible with S7‑400 CPUs (e.g., 414, 416, 417).
- Certified: CE, UL, CSA, IEC 60947‑5‑1.
- Suitable for NEMA motor starter size 5.
- Isolation: channel‑to‑channel, channel‑to‑bus (1500 V AC).
Typical Applications
- Switching AC contactors, solenoid valves, and pilot lamps.
- Industrial ovens, conveyor systems, and pumping stations.
- Retrofit of obsolete relay panels in power plants.
- Redundant output configurations for safety‑critical loads.
Diagnostic Capability
No built‑in diagnostics – but per‑channel green LEDs show output state.
Use PLC logic to monitor feedback for fault detection.
FAQ – Quick Answers
- Q: Can I parallel two outputs for higher current?
No for uprating, but yes for redundant control (same voltage). - Q: Minimum load current?
11 mA to ensure reliable switching. - Q: Is the module short‑circuit protected?
No. Add external fuse (max 5 A per channel). - Q: Max switching frequency for inductive loads?
1 Hz (per IEC 60947‑5‑1). - Q: Operating cycles?
100,000 electrical (AC‑15/DC‑13); 3,000,000 mechanical.
