Why Engineers Specify This Model
- High Channel Density: 32 inputs in a single Quantum slot minimizes rack space and reduces overall system cost compared to lower-density alternatives.
- Optical Isolation: Full galvanic isolation between field wiring and the backplane bus protects the CPU and other modules from field-side transients and ground loops.
- Deterministic Scan Performance: Tight integration with the Quantum backplane ensures consistent, predictable input scan times critical for time-sensitive process control loops.
- Wide Input Voltage Window: Accepts signals from 11 to 30 VDC, accommodating real-world field voltage variations without nuisance trips or false reads.
- Removable Terminal Block: The field-wiring connector can be removed without disturbing field cables, enabling fast module swap-out during maintenance windows.
- Proven Platform Longevity: The Modicon Quantum platform has decades of installed base in critical infrastructure; spare parts availability and engineering familiarity are well-established.
- Broad Environmental Rating: Rated for 0–60°C operation and 5–95% RH, suitable for most industrial panel and control room environments without additional conditioning.

Q: Is the 140DSI35300 compatible with all Modicon Quantum backplane sizes?
A: Yes. It is compatible with all standard Quantum backplanes (6, 10, 16-slot) including the 140XBP01600, 140XBP01000, and 140XBP00600 series, subject to power budget calculations.
Q: Can this module be used in a hot-standby (HSBY) Quantum configuration?
A: Yes. The 140DSI35300 is supported in Quantum HSBY architectures. Ensure your CPU and CHS module firmware versions are compatible per Schneider’s HSBY configuration guide.
Q: What is the maximum cable length for field wiring to this module?
A: Schneider Electric recommends a maximum of 300 m (1,000 ft) for 24 VDC discrete input wiring, subject to cable cross-section and voltage drop calculations. Use shielded cable in high-noise environments.
Q: Does the 140DSI35300 support IEC 61131-3 function block programming?
A: The module itself is a hardware I/O device. It is programmed and mapped via Unity Pro (now EcoStruxure Control Expert) using standard discrete I/O function blocks compliant with IEC 61131-3.
Q: Can I replace a 140DSI35300 with a 140DDI35300?
A: No. The 140DDI35300 is a different module (also discrete input but with different electrical characteristics). Always verify the exact part number before substitution. Contact us for cross-reference assistance.
