IQS900 204-900-000-011 A5-B23-C1-H10-I1 is an Ex-configured signal conditioner for TQ-series eddy-current proximity measurement systems, used as an Industrial Automation Part in vibration monitoring and rotating machinery applications. It processes the measurement signal from compatible proximity sensors and provides the conditioned output required by a monitoring or data-acquisition system for applications such as shaft vibration, shaft displacement, and rotor position monitoring. This specific configuration features the A5 Ex option, B23 sensitivity configuration, C1 without diagnostics, H10 for a 10 m total system length, and I1 with the MA130 DIN-rail mounting adaptor.

For this product, the complete ordering code is:
204-900-000-011-A5-B23-C1-H10-I1
Each section identifies an important part of the product configuration.
204-900-000-011
This is the base PNR for the IQS900 signal conditioner.
A5
A5 = Ex configuration
This option identifies the IQS900 version intended for applicable hazardous-area installations.
The A5 designation is therefore an important part of the product identity and should not be omitted when sourcing a replacement for an existing Ex installation.
B23
B23 = 4 mV/µm sensitivity
This is the 4 mm measurement-range configuration of the IQS900 proximity measurement chain.
The manufacturer's current data sheet lists B23 with:
Sensitivity: 4 mV/µm
Typical linear measurement range: 0.3 to 4.3 mm
The actual usable measurement performance depends on the complete measurement chain, target material, and installation conditions.
C1
C1 = Without diagnostics
The C1 version does not include the optional diagnostic circuitry.
This distinction is important because the IQS900 family also includes C2 diagnostic configurations. A C1 unit should therefore not be automatically substituted for a C2 unit in an application where measurement-chain diagnostics or safety functions are required.
H10
H10 = 10 m total system length
The H option identifies the total measurement-chain length configuration.
This product is configured for a 10 m system.
I1
I1 = MA130 DIN-rail adaptor included
The I1 configuration includes the MA130 mounting adaptor, allowing the IQS900 to be installed using the corresponding DIN-rail mounting arrangement.
This is different from the I0 configuration, where the adaptor is not included.
Ex Version for Hazardous Areas
One of the most important differences between this product and the standard A1 version is the:
A5 – Ex configuration
The manufacturer identifies A5 as the Ex option for the IQS900.
For an IQS900 with Ex protection installed in an Ex Zone 2 environment, the manufacturer's safety documentation specifies additional installation requirements, including installation within an appropriate industrial housing or enclosure providing at least the required protection level.
Therefore, customers purchasing this product for a hazardous-area project should verify:
Ex zone classification
Required protection concept
Applicable certificate
Sensor certification
Cable configuration
Installation enclosure
System-level certification requirements
Important: The A5 code alone should not be treated as universal approval for every hazardous location. The complete installation must comply with the applicable Ex documentation and certification.
TQ-Series Compatibility
The IQS900 operates as part of a compatible TQ-series proximity measurement chain.
Relevant Vibro-Meter / Meggitt product families include:
TQ4xx proximity measurement systems
TQ9xx proximity measurement systems
TQ9xx-series proximity sensors
EA402 / EA403 extension cable families
EA902 extension cable families, depending on the selected measurement chain
The applicable sensor, cable, and IQS900 configuration must be matched according to the intended measurement chain.
The current Meggitt documentation for TQ942/EA902/IQS900 confirms the IQS900's role in the TQ9xx proximity measurement architecture and lists the available B21-B24 configurations.
Export Packaging
The IQS900 should be protected against shock, moisture and contamination during international transportation.
Recommended export packaging includes:
Inner protection → Individual carton → Shock-absorbing material → Outer export carton
For larger orders or shipments containing multiple industrial automation components, additional wooden packaging can be used when appropriate.
The final packed dimensions and gross weight should be confirmed after packaging rather than relying only on product dimensions.
FAQ
Q: What does A5 mean on the IQS900?
A: A5 identifies the Ex configuration of the IQS900. It is intended for applicable hazardous-area applications subject to the relevant certification and installation requirements.
Q: Which sensors can be used with the IQS900?
A: The IQS900 is associated with compatible Vibro-Meter / Meggitt TQ-series proximity measurement chains, including applicable TQ4xx and TQ9xx configurations. The exact sensor and cable combination should be verified against the complete system configuration.
Q: Does the IQS900 include the proximity sensor?
A: The IQS900 is the signal conditioner. A complete proximity measurement chain may additionally require a compatible TQ-series sensor and extension cable.
Q: Does this product include the DIN-rail adaptor?
A: Yes. The I1 configuration includes the MA130 DIN-rail adaptor.
Q: How many Ethernet interfaces does this module support?
A: Standard CPU module support:
Q: 2 Ethernet interfaces
