SCHNEIDER 140CRA21210 is a DIO (Digital Input/Output) station adapter and power supply module in the Modicon Quantum series PLC (Programmable Logic Controller) range from Schneider Electric.
Below are the detailed specifications and information about this product:
1. Basic Description
- Product Name: 140CRA21210
- Product Type: DIO Embedded Interface (Digital Input/Output Embedded Interface)
- Applicable Platform: Modicon Quantum series PLC
- Power Supply Rating: 115/230 VAC
- Key Features: Independent power supply, 3 A current capacity, single-cable design
- Application: Used to connect field digital signals (such as switches and sensor status signals) to the Quantum PLC system.
2. Detailed Technical Specifications
- Power Supply Type: 115/230 VAC (suitable for the two most common industrial voltage levels)
- Current Capacity: 3 A (suitable for standard digital input/output requirements)
- Interface Design: Single-cable configuration (compared with the dual-cable version 140CRA21210C, the single-cable design is more suitable for applications requiring simplified wiring).
- Redundancy Design: No redundant ports (compared with models such as 140CRA21110 with a single port or 140CRA21220 with dual ports, this module primarily provides power supply functionality).
3. Alternatives and Compatibility
- Related Products: Within the Quantum series, similar modules include the 140CRA21110 (115/230 VAC single-port DIO) and the 140CRA21220 (24 VDC dual-port DIO).
- Variants: A conformal-coated variant (140CRA21210C) is available for use in highly corrosive environments.
