Overview
The Siemens 6ES7 134-6GF00-0AA1 is a SIMATIC ET 200SP analog input module designed for flexible current signal acquisition in distributed automation systems. This AI 8xI 2-/4-wire Basic module provides eight asymmetric analog inputs supporting standard industrial ranges (0–20 mA, ±20 mA, 4–20 mA) with 16-bit digital resolution and exceptional 0.05% accuracy. It integrates seamlessly into ET 200SP decentralized I/O stations, enabling hot-swap capability for zero-downtime module replacement.
Key Features
- 8 asymmetric analog input channels with 2-/4-wire sensor configuration support
- Multiple input signal ranges: 0–20 mA, ±20 mA, 4–20 mA
- 16-bit resolution with 0.05% measurement accuracy
- Integrated 24V sensor supply with short-circuit protection and 0.7 A maximum output current
- Hardware status FS04 or higher; supports firmware updates
- 1 ms cycle time per channel; maximum 200 m shielded cable length
- IP20 degree of protection; mechanical Type A coding element
- Module diagnostics and color coding (CC01) for rapid identification
Technical Specifications
This module operates with 16-byte maximum address space and delivers a normal power dissipation of 0.7 W (without sensor supply). The maximum permissible input current is 50 mA for protection against overcurrent damage. Its compact dimensions (15 mm W × 73 mm H × 58 mm D) support space-efficient installation in control cabinets and integrated machine control systems. Current consumption is 25 mA without sensor power supply, making it suitable for high-channel-count I/O configurations.
Typical Applications
- Distributed control systems requiring modular analog input acquisition
- Process monitoring with 4–20 mA transmitter integration
- Machine automation with decentralized sensor networks
- Pressure, temperature, and flow measurement data collection
- Field-mounted I/O stations in harsh industrial environments
- Retrofit and expansion of existing SIMATIC ET 200SP configurations
Compatibility & Replacements
The 6ES7 134-6GF00-0AA1 mounts on ET 200SP Base Unit type A0 and A1 frames and requires SIMATIC S7-1200, S7-1500, or TIA Portal V16+ programming platforms for configuration. It is not interchangeable with other analog input modules outside the ET 200SP series (such as S7-300 SM 331 or S7-400 SM 431). For voltage-input analog data or different channel counts, refer to the ET 200SP AI 8xU (voltage) or AI 4xI modules. Always verify hardware functional status and firmware compatibility before installation.
