Function of the IQS450 in an Industrial Automation System
The IQS450 performs signal-conditioning functions between the proximity transducer and the machinery monitoring system.
Its position within the system can be described as:
Proximity Measurement
The TQ 402 or TQ 412 measures the distance between the probe and the conductive shaft or target.
Signal Conditioning
The IQS450 provides the required transducer excitation and processes the measurement signal.
Monitoring
The conditioned signal can then be connected to suitable machinery monitoring or protection equipment.
Control / Plant System
Depending on the overall installation, measurement information can subsequently be used by a machinery protection system, monitoring platform, DCS, PLC or other plant-level system.
The IQS450 therefore functions as an interface component within the complete machinery monitoring architecture.
Compatible With
The IQS450 204-450-000-001 A1-B23-H05-I0 Signal Conditioner is designed to operate as part of a complete Vibro-Meter proximity measurement system. It is not intended for standalone use and should be installed with compatible proximity transducers, extension cables, and monitoring modules to ensure proper measurement accuracy and system performance. Before installation or replacement, verify that the product model and configuration code match the existing system.
Machine Shaft / Conductive Target → TQ 402 or TQ 412 → EA 402 Extension Cable → IQS450 → Monitoring or Protection System
TQ Series Proximity Transducers
The IQS450 is compatible with Vibro-Meter TQ series proximity transducers, which detect the distance between the probe tip and a conductive target using non-contact eddy-current technology. Together with the signal conditioner, the probe forms the primary sensing element for shaft vibration, shaft displacement, axial position, and eccentricity measurements.
EA Series Extension Cables
The signal conditioner is designed to work with EA series extension cables, which connect the TQ proximity transducer to the IQS450. The probe, extension cable, and signal conditioner are calibrated as a complete measurement chain, making it important to use the specified cable type and length for the selected configuration.
VM600 Machinery Monitoring System
The IQS450 is widely used in the Vibro-Meter VM600 Machinery Monitoring System, where conditioned sensor signals are transmitted to monitoring modules for continuous machinery condition monitoring, alarm processing, and machine protection. The VM600 platform is commonly applied in critical rotating equipment across power generation, oil and gas, petrochemical,l and other industrial sectors.
MPC4 Machinery Protection Card
The conditioned output from the IQS450 can be used with the MPC4 Machinery Protection Card, enabling continuous monitoring of vibration and displacement parameters. The monitoring module evaluates sensor signals, generates alarm and trip functions, and communicates measurement data to higher-level control systems.
CPUM System Controller
Within a VM600 rack, the CPUM (Central Processing Unit Module) manages system communication, configuration, and data processing. When used together with the IQS450 and monitoring modules, the CPUM provides centralized management of machinery monitoring data and system diagnostics.
IOCN Communication Module
The IOCN communication module provides communication and data exchange between the VM600 monitoring system and plant control systems such as DCS, PLC, or SCADA platforms. The IQS450 supplies conditioned measurement signals that can be processed and transmitted through the VM600 architecture.
Typical Rotating Machinery
The IQS450 is commonly installed in machinery requiring continuous condition monitoring, including:
Steam Turbines
Gas Turbines
Hydroelectric Generators
Centrifugal Compressors
Pumps
Electric Motors
Industrial Fans
Turbo Expanders
Blowers
Large Rotating Process Equipment
System Compatibility Recommendations
Before purchasing or replacing an IQS450 signal conditioner, it is recommended to verify:
Complete product model and ordering code
Compatible TQ series proximity transducer
Matching EA series extension cable
VM600 monitoring module configuration
Existing machinery protection system
Installation drawings and wiring configuration
Confirming the compatibility of the complete measurement chain helps reduce commissioning time, minimizes replacement risks, and ensures the signal conditioner operates correctly within the existing monitoring system.
