IBA ibaMS3xAI-1A Precision AC Current Measurement Module

IBA ibaMS3xAI-1A: Precision AC Current Measurement Module

The ibaMS3xAI-1A is a specialized analog input module within the ibaMS (Modular System) family.

It is specifically engineered for high-precision, direct measurement of AC currents up to 1 A, making it a vital component for power quality monitoring and electrical asset diagnostics.

Technical Parameter Table

Product Advantages and Features

Direct CT Connection: Specifically designed to interface with the secondary side of standard current transformers (1 A output), eliminating the need for external transducers.

Phase-Synchronous Sampling: When used within the ibaMS rack, all three phases are sampled simultaneously, which is critical for accurate power factor and harmonic calculations.

High Electrical Safety: Robust galvanic isolation ensures that high-voltage surges on the primary side do not damage the sensitive data acquisition hardware.

Seamless Integration: Fully supported by ibaPDA, allowing for real-time visualization of waveforms and automated reporting of energy metrics.

Related Models & Same Series

The ibaMS (Modular System) allows you to mix and match various input types in a single rack:

ibaMS3xAI-5A: The high-current variant designed for 5 A AC secondary currents.

ibaMS4xAI-V: Standard voltage input module for DC and AC signals.

ibaMS8xDI: Digital input module for status and event monitoring.

ibaMS-Central: The head station/CPU required to power and manage the AI modules.

Application Cases

Energy Monitoring: Monitoring the power consumption of large industrial motors by measuring the three-phase currents via existing 1 A current transformers.

Fault Recording: Acting as a high-speed "black box" to capture current spikes or phase imbalances during electrical faults.

Preventive Maintenance: Analyzing the harmonic content of currents to detect early signs of insulation failure or bearing wear in large pumps and fans.

Installation and Maintenance

Installation: The module must be snapped into an ibaMS subrack. Ensure that the 1 A current transformer circuit is never opened while the primary side is live (always short-circuit the CT before removing the module).

Wiring: Use twisted-pair cabling for the 1 A signals to minimize electromagnetic interference in high-current environments.

Maintenance: No recalibration is typically required in the field. Check terminal tightness annually, especially in high-vibration industrial settings.

Unique Product Description

The ibaMS3xAI-1A provides a clear, high-resolution heartbeat for your electrical systems. By capturing AC currents at the source with 16-bit precision, it turns raw electricity into actionable data.

Whether you are hunting for elusive harmonics or calculating precise energy costs, this module provides the industrial-grade reliability needed to bridge the gap between high-power electrical racks and digital analytics.
