Omron CP1W-20EDT1 Digital I/O Expansion Unit - 12 Input/8 Output PLC Module

Product Overview

The Omron CP1W-20EDT1 represents a high-performance digital input/output expansion unit specifically engineered for seamless integration with Omron CP1 series programmable logic controllers (PLCs). This industrial automation component delivers 12 high-speed DC inputs and 8 reliable transistor outputs (sinking type) in a compact form factor, providing essential signal processing capabilities for modern control systems. Designed for demanding industrial environments, the module features robust construction with a 0°C to 55°C operating temperature range and vibration-resistant design. With dimensions of just 90×65×65 mm (W×H×D) and weighing only 300g, this expansion unit offers space-efficient panel mounting without compromising on functionality or performance.

Key Features and Benefits

• Precision Digital I/O Configuration: 12-point 24V DC input (4.7kΩ impedance, 6mA typical current) with 8-point transistor output (sinking/NPN type, 0.5A per point capacity, 2.0A common terminal maximum)
• Industrial-Grade Durability: Constructed with high-quality components rated for continuous operation in harsh industrial environments (0°C to 55°C operating temperature, 10-90% non-condensing humidity)
• Optimized Power Efficiency: Low power consumption design (50mA maximum at 5V DC internal supply) reduces overall system load and operational costs
• High-Speed Signal Processing: Exceptional input response time of 1ms maximum (OFF→ON) and 2ms maximum (ON→OFF) for precision timing applications
• Reliable Output Performance: Transistor outputs feature rapid switching times of 0.1ms maximum (OFF→ON) and 0.3ms maximum (ON→OFF) for responsive control
• Enhanced Noise Immunity: Photocoupler isolation between internal and I/O circuits with 1,500Vp-p noise voltage protection for stable operation in electrically noisy environments
• Mechanical Resilience: Vibration resistance (10-57Hz: 0.075mm amplitude, 57-150Hz: 9.8m/s² acceleration) and shock resistance (147m/s² in 6 directions) for industrial durability
• Standard Warranty Coverage: Backed by Omron's comprehensive 1-year manufacturer warranty against defects in materials and workmanship

Compatibility Information

The CP1W-20EDT1 digital I/O expansion unit is specifically designed for seamless integration with Omron CP1 series programmable logic controllers, including CP1E, CP1L, and CP1H models. When planning your control system configuration, please note that the maximum number of connectable expansion units varies by CPU unit model (typically 3-7 units depending on specific PLC model). The expansion unit connects directly to the CPU unit or another expansion unit via the built-in expansion connector, requiring no special cables or adapters. Always verify power supply capacity when adding multiple expansion units to ensure proper system operation.
