Why the 140AMM09000C Belongs in Your Quantum Rack
When analog signals drift or noise corrupts your process readings, production quality suffers. The 140AMM09000C from Schneider Electric solves this with a purpose-built analog input module for the Modicon Quantum platform. It converts four analog field signals into digital data your CPU can act on, while a single-pole low-pass filter at 21 Hz strips out high-frequency interference before it reaches your control logic.
This is not a generic I/O card. It is a Quantum-native module that speaks the backplane protocol directly, so integration is clean and predictable.
Technical Specs That Matter on the Plant Floor
Four Analog Inputs with Built-In Filtering
The 140AMM09000C accepts four analog inputs. The 21 Hz single-pole low-pass filter is the standout feature: it attenuates noise above 21 Hz, which is ideal for slow-moving process variables like temperature, pressure, and level. You get cleaner data without adding external signal conditioners.
Data Handling: 5 Input Words, 2 Output Words
The module exchanges five input words and two output words with the Quantum CPU. This fixed data map simplifies PLC programming and keeps scan-time overhead predictable.
Power and Environmental Envelope
It draws 350 mA from the backplane bus. Operating temperature spans 0 to 40 degrees Celsius, humidity up to 80% non-condensing, and altitude up to 1000 m above sea level. Weighing just 0.3 kg, it installs quickly into existing racks.

Where This Module Earns Its Keep
Oil and Gas Processing
In upstream and midstream facilities, the 140AMM09000C handles analog inputs from pressure transmitters and flow meters. The 21 Hz filter rejects pump-induced noise, giving your DCS or SCADA accurate readings for custody transfer and safety monitoring.
Water Treatment and Chemical Blending
Slow process loops benefit from the module’s filtering. Level and pH signals stay stable even when nearby VFDs introduce electrical noise.
Upgrading Legacy Quantum Systems
If you run an existing Modicon Quantum rack, this module is a drop-in expansion. It uses the same backplane and programming environment, so no gateway or protocol conversion is needed. For plants standardizing on Quantum, the 140AMM09000C is a practical way to add analog capacity without a full platform migration.
Integration and Commissioning Notes
The module resides in a Quantum backplane and communicates natively with the Quantum CPU. No external gateway is required for this module. When planning your installation, verify that your power supply can deliver the additional 350 mA bus current. Confirm slot compatibility and terminal wiring against your Quantum rack documentation. Because the module has no external filter adjustments, commissioning is limited to configuring the data words in your PLC program.
Maintenance and Long-Term Reliability
The 140AMM09000C has no moving parts, so wear is minimal. In practice, reliability depends on the operating environment. Keep cabinet temperature within the 0 to 40 degrees Celsius range and humidity below 80% non-condensing. At altitudes above 1000 m, derating may apply—check your system manual. Periodically inspect terminal connections for corrosion or loosening, especially in oil and gas installations where vibration is common. A spare module on the shelf minimizes downtime; Oil AutoTech keeps this unit ready-to-ship for fast dispatch, worldwide.
Choosing the Right Analog Input Module
Before you buy, confirm three things: your Quantum rack has an open slot, your power budget accommodates 350 mA, and your signal types match the module’s analog input range.
