Product Description

The AI204/2 is a high-precision analog input expansion module designed for the Bachmann M1 controller environment. This module interfaces seamlessly with standard industrial sensors, providing reliable signal acquisition for complex closed-loop control systems. Unlike basic input cards, the AI204/2 features enhanced galvanic isolation, protecting the internal system bus from external electrical interference and potential surges common in heavy industrial sites.

Core Functional Performance

• Integrates four independent input channels, each capable of processing high-resolution signals.

• Supports multiple input ranges, including standard voltage (±10 V) and current (0/4–20 mA) signals, enabling versatile deployment without additional signal converters.

• Optimized Analog-to-Digital (A/D) conversion for low latency, ensuring real-time data delivery to the CPU for critical process adjustments.

Technical Specifications

Deployment and Compatibility

The AI204/2 is widely used in:

• Energy management systems

• Maritime engine monitoring

• Automated manufacturing lines

Its rugged construction ensures stable calibration even in high-vibration environments, making it ideal for applications such as:

• Wind turbine pitch control

• Hydraulic system monitoring

Product FAQ

Q: Does this module require external power for the sensors?
A: Yes, the AI204/2 typically requires an external 24 V DC supply to power the field-side electronics and connected 2-wire transmitters.

Q: What is the difference between this and the standard AI204?
A: The AI204/2 variant includes updated internal filtering and improved thermal stability, providing better performance in extreme temperature fluctuations compared to earlier revisions.
