Why Engineers Specify This Model
- High Channel Density – 32 AC inputs in a single Quantum slot reduces rack space and wiring cost versus dual 16-channel alternatives.
- Robust Optical Isolation – Group isolation protects the backplane and CPU from field-side transients and ground loops common in AC environments.
- Wide Voltage Window – 74–132 VAC tolerance accommodates real-world line fluctuations without nuisance faults.
- Removable Terminal Block – Field wiring stays in place during module swap, minimising maintenance downtime.
- Proven Quantum Ecosystem – Direct compatibility with 140CPU, 140CRP, and 140NOE network modules; no gateway or adapter required.
- Long Product Lifecycle – Schneider Electric maintains extended support for Quantum hardware, protecting capital investment in existing rack infrastructure.
- Diagnostics via Unity Pro / EcoStruxure Control Expert – Per-channel status bits and module health flags are natively readable in the PLC program.

Application-Specific FAQ
Q: Can the 140DAI74000 accept 240 VAC field signals?
A: No. The module is rated for 120 VAC nominal (74–132 VAC range). For 240 VAC applications, use the 140DAI75300 (32-ch, 230 VAC input) instead.
Q: Is this module compatible with the Modicon M340 or M580 platform?
A: No. The 140DAI74000 is exclusively for the Modicon Quantum backplane. M340 uses BMX-series I/O; M580 uses BMEX-series I/O.
Q: How many 140DAI74000 modules can be installed in one Quantum rack?
A: Up to 15 I/O modules per 16-slot rack (one slot reserved for the CPU or power supply), subject to backplane current budget. Verify total 5 VDC draw against your 140CPS power supply rating.
Q: What software is required to configure this module?
A: EcoStruxure Control Expert (formerly Unity Pro) v13.1 or later is recommended. The module is auto-detected by the Quantum hardware catalog; no additional driver installation is required.
Q: Do you supply the removable terminal block connector?
A: The 40-pin terminal block is included with new-in-box units. For refurbished or used-tested units, please confirm connector inclusion at time of order. Spare connectors are available separately.
Q: What is the typical lead time for out-of-stock units?
A: Lead times vary by market conditions. Contact us for a real-time availability check. We maintain relationships with multiple authorised and surplus distributors to minimise lead time.
