Schneider Electric 140 ACI 030 00 – 16-Channel Analogue Input Module | Modicon Quantum Platform
Engineering Background: The Modicon Quantum series represents Schneider Electric’s flagship high-performance PLC platform, engineered for mission-critical process automation in industries where signal integrity and system uptime are non-negotiable. The 140 ACI 030 00 is a dedicated analogue input module designed to interface field-level sensors and transmitters directly with the Quantum backplane, delivering precise, noise-immune signal acquisition across 16 independent channels.
Product Positioning: Targeted at process control engineers and system integrators working in oil & gas, chemical processing, power generation, water treatment, and heavy manufacturing, the 140 ACI 030 00 provides the analogue front-end backbone for closed-loop control strategies. Its compatibility with standard 4–20 mA and 0–10 V field instruments makes it universally deployable across legacy and greenfield installations.

- Galvanic Isolation: 500 V AC channel-to-backplane isolation protects the CPU from field-side transients and ground loops.
- Hot-Swap Ready: Supports live insertion/removal on Quantum backplanes with RIO/DIO configurations, enabling maintenance without system shutdown.
- Diagnostics: Per-channel open-wire and over-range detection with status bits mapped directly to the process image table.
- Unity Pro / Concept / ProWORX Compatible: Fully supported by all Schneider Electric Quantum programming environments.
System Architecture & Signal Flow
The 140 ACI 030 00 occupies a single slot on any Modicon Quantum 140 XBP backplane. Field wiring connects via the front-panel terminal block (Telefast or direct screw terminals). Analogue signals are multiplexed through a 16:1 MUX, digitised by a 12-bit successive-approximation ADC, and transferred to the backplane data bus each PLC scan cycle. The module’s internal microprocessor handles channel sequencing, self-calibration, and diagnostic flag generation autonomously, offloading the CPU from signal conditioning tasks. In Remote I/O (RIO) or Distributed I/O (DIO) topologies, the module operates identically under the 140 CRP / 140 NOE head-end adapters.

Technical FAQ
Q: Is the 140 ACI 030 00 compatible with Modicon Premium or M340 platforms?
A: No. This module is exclusively designed for the Modicon Quantum 140-series backplane. It is not compatible with Premium TSX or M340 racks.
Q: Can I mix current and voltage inputs on the same module?
A: Yes. Each channel is individually configurable for current or voltage input via software parameter settings in Unity Pro / Concept.
Q: What is the maximum cable length for field wiring?
A: Schneider Electric recommends shielded twisted-pair cable up to 300 m for current inputs (4–20 mA) and up to 100 m for voltage inputs (0–10 V) in standard industrial environments.
Q: Does the module support HART protocol?
A: No. The 140 ACI 030 00 is a standard analogue module and does not support HART communication. For HART-enabled analogue input, refer to the 140 AHI 330 00.
Q: What firmware version is required on the Quantum CPU?
A: The module is compatible with all Quantum CPU firmware versions from V2.0 onwards. No special firmware is required.
