Original Bachmann AI204/2 Isolated Analog Input Interface

Product Overview

The Bachmann AI204/2 (AI204/2) stands as a high-precision analog input solution for the M1 automation system. This module captures critical sensor data with 16-bit resolution across two fully isolated channels. It serves as the primary interface for high-accuracy signal measurement in complex automation environments, such as wind turbine pitch control, power plant monitoring, and high-speed manufacturing lines. By utilizing advanced delta-sigma conversion technology, the AI204/2 filters out electrical noise and delivers stable data to the controller. This module ensures 100% brand new, original factory quality, providing a robust backbone for real-time signal processing and system safety.

Technical Specifications

Engineering Advantages

The AI204/2 addresses the most challenging data acquisition hurdles in modern industrial sites:

• Superior Noise Immunity: The delta-sigma converter architecture naturally suppresses high-frequency interference. Coupled with galvanic isolation for every channel, this module prevents ground loops and ensures clean signal acquisition even in environments with heavy electromagnetic motor noise.

• High-Speed Control Loops: A rapid 20 µs minimum sampling rate allows the controller to react to dynamic process changes in real-time. This speed proves essential for vibration monitoring and fast-acting safety shutdowns in energy applications.

• M1 Backplane Synergy: This module slides directly into the Bachmann M1 rack, drawing power and synchronizing clock cycles with other digital and analog units. This native integration reduces wiring complexity and commissioning time.

• Compact Scalability: The narrow 2.2 cm width allows engineers to pack high-density analog measurement into minimal cabinet space, reducing the overall footprint of the control assembly.

FAQs

• Does the AI204/2 support current inputs (4-20 mA)?

  The standard AI204/2 hardware measures voltage ranges of –10 V to +10 V. For 4-20 mA current signals, you must apply an external precision shunt resistor or use a Bachmann current-specific input module.

• How does galvanic isolation benefit my system?

  Galvanic isolation separates the input circuit from the backplane and other channels. This protects the M1 CPU from voltage surges at the field level and eliminates cross-talk between different sensors.

• Is the AI204/2 compatible with older Bachmann M1 CPUs?

  Yes, the AI204/2 maintains backward compatibility with the M1 series hardware. Ensure your Bachmann SolutionCenter software reflects the correct hardware revision for optimal configuration.

• What is the standard delivery timeframe?

  We ship original AI204/2 units via DHL or FedEx within 3 to 14 days, depending on your order volume and current inventory levels.
