Information About 6ES7321-1FH00-0AA0

The 6ES7321-1FH00-0AA0 is a Siemens S7-300 series AC digital input module engineered to capture signals from field devices operating across a wide AC voltage range. Its 16 optically isolated channels ensure electrical separation between field wiring and internal PLC electronics, enhancing system safety and noise immunity. Designed to integrate directly with S7-300 controllers, it occupies minimal cabinet space and provides dependable signal acquisition for manufacturing, process control, and infrastructure applications. With a low power requirement of 4.9 W and a compact footprint, it contributes to efficient panel design and scalable control architectures.

Key Features:

  • 16 Optically Isolated AC Inputs: Ensures safe and noise-resistant signal transmission from field devices.
  • Wide AC Voltage Compatibility: Accepts input ranges from 0–40 VAC and 74–264 VAC for versatile system integration.
  • Reliable DIN-Rail Integration: Designed to install easily within S7-300 racks or mounting systems.
  • Low Power Consumption: Operates at only 4.9 W while supporting full input channel capability.
  • Compact Mechanical Design: Measures 120 × 40 × 125 mm for space-efficient control cabinet layouts.
  • Robust Industrial Performance: Handles typical automation environments with dependable electrical isolation.
  • Direct Compatibility with S7-300: Seamlessly integrates into Siemens’ established PLC platform for scalable system expansion.
  • Stable Input Processing: Provides consistent signal detection for AC-based sensors, switches, and control devices.

The 6ES7321-1FH00-0AA0 delivers the reliability and precision required for accurate AC signal acquisition in demanding industrial control systems.
