Description
The 140DAO84220C is a ruggedized, high-density discrete alternating current (AC) output module designed for the Schneider Electric Modicon Quantum automation platform. Featuring 16 output channels organized into two independently isolated groups of 8, this module provides reliable switching for 100-240 VAC field loads. The "C" suffix indicates that the module is equipped with an integrated conformal coating, offering enhanced protection against humidity, dust, and airborne chemical contaminants. This design ensures long-term operational reliability in harsh industrial environments such as petrochemical refining, water treatment, and power generation.
Features
- 16 discrete AC output channels.
- Two isolated groups of 8 channels each for flexible wiring configurations.
- Conformal coating for superior resistance to corrosive atmospheres and moisture.
- Galvanic isolation of 1780 VAC between field-side and backplane logic.
- Integrated status diagnostics including 16 channel-specific green LEDs, a Ready status LED, and a Module Error LED.
- Supports nominal voltages of 120 VAC and 230 VAC.
Applications
This module is engineered for demanding industrial control applications where environmental stressors are present. Typical use cases include controlling AC actuators, contactors, and solenoid valves in water treatment plants, mining operations, and thermal power facilities where protection against salt spray or chemical vapors is required.

Installation Guidelines
- Ensure the Quantum backplane is powered down before inserting or removing the module to prevent electrical damage.
- The module must be seated firmly into the rack and secured using the integrated locking mechanisms.
- Use shielded cabling for field wiring to minimize EMI interference, especially in high-noise industrial areas.
- Maintain proper ventilation within the control cabinet to ensure the module operates within its specified temperature range (0 to 60 degC).
- Handle with care to avoid damaging the conformal coating on the internal PCB assembly.
FAQ
What does the C suffix mean in 140DAO84220C?
The C suffix denotes that the module has been manufactured with a conformal coating. This is a protective polymer layer applied to the internal circuitry to shield components from moisture, dust, and corrosive gases, making it suitable for harsh environments.
Can this module be used in hazardous locations?
Yes, the 140DAO84220C is rated for FM Class 1 Division 2 environments, provided it is installed in accordance with local safety regulations and within an appropriate enclosure.
