HBM MP30DP Amplifier

HBM MP30DP Instrumentation Amplifier Module – Precision Signal Conditioning for Industrial Applications

The HBM MP30DP is a high-precision instrumentation amplifier module designed for use within HBM's PME (Precision Measurement Electronics) modular data acquisition systems. Manufactured by HBM (Hottinger Baldwin Messtechnik), a globally recognized name in measurement technology, the MP30DP is engineered to handle demanding signal-conditioning applications in industrial environments.

This module operates as a carrier-frequency amplifier, utilizing a 600 Hz carrier-based modulation to ensure stable and accurate signal amplification. It is particularly optimized for signals originating from sensors like strain gauges, force transducers, and pressure sensors. The carrier-frequency technique significantly enhances immunity to electrical noise—making it highly suitable for industrial settings where electromagnetic interference is a concern.

One of the key features of the MP30DP is its built-in Profibus-DP interface, which enables real-time digital communication with PLCs, SCADA systems, and other industrial controllers. This plug-and-play fieldbus integration allows for seamless incorporation into existing automation networks, eliminating the need for additional interface converters or manual signal interpretation.

Operating on a 24 V DC power supply, the MP30DP provides reliable performance within a compact and robust IP20-rated housing, meant for installation inside electrical cabinets. The form factor is modular and designed for PME rack systems, allowing users to mix and match with other HBM modules based on their specific signal processing needs.

Though discontinued by the manufacturer, the MP30DP remains a preferred choice in legacy systems due to its proven reliability and integration simplicity. It continues to see demand in industries such as manufacturing automation, process control, mechanical testing, and structural monitoring—especially where high-resolution sensor data must be captured and processed in real time.

With a weight of approximately 0.82 kg, the module is relatively lightweight, allowing for flexible placement within control panels. Its availability now is limited to surplus, open-box, or refurbished markets, where it is sold through specialized automation resellers. Pricing for these modules typically ranges from $600 to $1,900, depending on condition and testing certifications.

Despite being out of production, the MP30DP continues to serve as a reliable solution for signal amplification and data transmission in advanced measurement systems. At Anadi Automation, we provide access to refurbished and tested MP30DP modules, ensuring quality assurance and operational continuity for our customers using HBM-based infrastructure.
