Product Introduction
When industrial control systems demand reliable signal acquisition, the Schneider 140DAI34000C provides a robust solution. This discrete input module belongs to the Modicon Quantum series, offering 16 input channels designed for 24 V AC operation. With CE marking and compliance to UL 508 and CSA standards, the 140DAI34000C ensures high-quality data collection in demanding environments. Whether you are upgrading an existing system or building a new installation, this module delivers consistent performance and long service life.
Technical Specifications Breakdown
The Schneider 140DAI34000C packs essential features for efficient discrete input handling. Key specifications from the manufacturer include:
-
Input Channels: 16 – allows monitoring of multiple digital signals simultaneously.
-
Input Voltage: 24 V AC – compatible with standard AC sensor outputs.
-
Input Current: 10.7 to 12 mA – provides reliable detection over a defined range.
-
Max Leakage Current: 1.9 mA – minimizes false triggering caused by leakage.
-
Bus Current Requirement: 180 mA – ensures stable operation within the Quantum backplane.
-
Max Power Dissipation: 5.5 W – contributes to energy efficiency and reduced heat load.
These specifications translate into lower total cost of ownership. The low leakage current reduces nuisance alarms, while the moderate power dissipation extends component life and cuts cooling needs – a clear return on investment for continuous operations.
Industry Applications
The 140DAI34000C serves a wide range of applications. In manufacturing lines, it monitors presence sensors and limit switches at 24 V AC. In packaging machinery, it reads position signals from conveyors. For energy management systems, the module acquires status signals from circuit breakers and contactors. Its robust design and compliance to UL 508 and CSA make it suitable for North American industrial installations. By leveraging the low power dissipation (5.5 W) and high leakage tolerance, users achieve sustained uptime and reduced maintenance intervals.
Compatibility & Integration
The 140DAI34000C is engineered for seamless integration into Modicon Quantum automation platforms. It requires a single input word for addressing, simplifying programming in Unity Pro or other Quantum-compatible environments. The standard module format fits easily into any Quantum rack slot. No special adapters are needed – it works directly with the Quantum backplane. For comprehensive system compatibility, always verify your rack power supply capacity to accommodate the 180 mA bus current draw. The module also pairs with other Quantum I/O modules for complete system solutions.
Selection Guide & Purchasing Advice
Before purchasing the 140DAI34000C, ensure your system uses Modicon Quantum backplane and supports 24 V AC discrete inputs. Confirm that your power supply can provide the required bus current.
