The 6ES7350-1AH03-0AE0 is a counter module from Siemens’ SIMATIC S7-300 series, specifically the FM 350-1 model, designed for precise counting and position monitoring in industrial automation systems.
Key Features:
- Channel Configuration: Equipped with 1 channel dedicated to counting tasks, supporting high-precision measurement of rotational or linear movements.
- Counting Capabilities:
- Compatible with incremental encoders (HTL/TTL signal types), enabling up/down counting, preset counting, and frequency measurement.
- Supports a maximum counting frequency of 100 kHz, ensuring responsiveness for fast-moving applications.
- Offers flexible counting modes, including single-phase, two-phase (with direction detection), and pulse/direction signaling.
- Functionalities:
- Integrates preset value and comparison functions, allowing the module to trigger actions (e.g., machine stops, alarms) when user-defined counts are reached.
- Includes interrupt capabilities for real-time event handling, enhancing system reactivity to critical counting thresholds.
- Features diagnostic functions such as wire break detection for connected encoders, with status LEDs for visual troubleshooting.
- Integration & Power:
- Connects via the S7-300 backplane bus, enabling seamless communication with S7-300 CPUs (e.g., CPU 312 to 319) without additional wiring.
- Requires a 24 V DC power supply for encoder signal processing, with logic power derived from the backplane bus.
- Mechanical Design:
- Compact, DIN rail-mountable housing, fitting standard S7-300 rack systems for space-efficient installation in control cabinets.
- Complies with industrial standards (e.g., CE, UL) for reliable operation in harsh environments (temperature ranges, vibration, EMC immunity).
Applications:
Ideal for scenarios requiring accurate counting or position tracking, such as:
- Monitoring part quantities on production lines.
- Measuring conveyor belt speeds or distances.
- Controlling machine tool positioning via encoder feedback.
- Synchronizing movements in packaging, material handling, or automotive assembly systems.
This module combines high precision, flexibility, and seamless S7-300 integration, making it a key component for automated systems demanding reliable counting functionality.
