Compatible Replacement & Equivalent Models
When the 140ACO04000C is unavailable or end-of-life, the following models are commonly evaluated as replacements. Compatibility depends on firmware version, rack configuration, and application requirements — always validate before installation.
- 140ACO04000 — Earlier revision of the same module; functionally equivalent in most Quantum applications. Check revision compatibility with your Unity Pro / Concept software version.
- 140ACO13000 — 13-channel analog output variant for higher-density applications; same Quantum backplane, different channel count.
- 140AVO02000 — Voltage-only analog output module (±10 V); suitable when current output is not required.
- BMXAMO0410 — Modicon M340 platform analog output module; requires rack and software migration but offers a modern upgrade path.
- Third-party equivalents — Some system integrators use Wago, Beckhoff, or Phoenix Contact analog output modules with Quantum-compatible gateways. Consult your system architect before substitution.
Important: Konmask supplies genuine OEM parts. We do not sell counterfeit or re-labeled modules. All replacement recommendations above are based on publicly available Schneider Electric documentation.
Why Choose the Original 140ACO04000C
- Drop-in compatibility: No firmware changes or rack reconfiguration required when replacing like-for-like within the Quantum platform.
- Proven field reliability: The Modicon Quantum series has decades of deployment in mission-critical process industries.
- Software continuity: Fully supported by Schneider Electric Unity Pro and legacy Concept programming environments.
- Regulatory compliance: OEM certification marks (CE, UL) remain valid — critical for regulated industries such as pharmaceuticals and nuclear.
- Reduced commissioning risk: Identical hardware revision eliminates the need for re-validation in IQ/OQ/PQ-qualified processes.
Typical Applications
- Control valve positioner signals (4–20 mA) in oil & gas pipelines and refineries
- Variable frequency drive (VFD) speed reference output in water/wastewater treatment
- Analog setpoint transmission to temperature controllers in chemical batch processes
- Actuator control in power generation and utilities
- Process loop control in food & beverage and pharmaceutical manufacturing
System Compatibility
- Rack: Modicon Quantum I/O racks — 140 XBP 002 00, 140 XBP 006 00, 140 XBP 010 00, 140 XBP 016 00
- CPU: All Modicon Quantum CPUs (140 CPU series) running Unity Pro or Concept
- Power Supply: 140 CPS series Quantum power supply modules
- Remote I/O: Compatible with Quantum RIO drops via 140 CRA series adapters
- Software: Schneider Electric Unity Pro (all versions), Concept 2.6+
Selection Guide
Use the table below to identify the right analog output module for your Quantum system:
| Requirement | Recommended Model |
|---|---|
| 4-channel current output (4–20 mA), direct replacement | 140ACO04000C ✓ |
| 4-channel current output, earlier revision | 140ACO04000 |
| Higher channel density (13 ch) on Quantum | 140ACO13000 |
| Voltage output only (±10 V) | 140AVO02000 |
| Platform migration to M340 | BMXAMO0410 |

Replacement & Compatibility FAQ
Q: Is the 140ACO04000 (without the “C” suffix) a direct replacement for the 140ACO04000C?
A: In most cases, yes — the “C” suffix typically denotes a hardware revision. However, always verify with your Schneider Electric representative or check the Unity Pro hardware catalog for your specific firmware version before substituting.
Q: Can I use the 140ACO04000C in a Modicon Premium or M340 rack?
A: No. The 140ACO04000C is designed exclusively for the Modicon Quantum backplane. It is not physically or electrically compatible with Premium (TSX) or M340 (BMX) racks.
Q: What happens if I install a different revision of this module?
A: Minor revisions are usually backward compatible, but Unity Pro may generate a hardware mismatch warning. Always perform a test in a non-production environment and consult the Quantum hardware compatibility matrix.
Q: Do you supply modules with original Schneider Electric packaging?
A: Where available, yes. Surplus units may come in anti-static bags with original labels. All units include a Konmask inspection certificate regardless of packaging condition.
Q: Can Konmask help me migrate from Quantum to a newer Schneider platform?
A: Yes. Contact our engineering team for a migration consultation. We can supply both legacy Quantum parts for short-term maintenance and M340/M580 components for long-term modernization projects.
