16-Point Digital I/O Expansion Module CP1W-40EDT with Relay Outputs

Product Overview

The CP1W-40EDT is a high-performance digital I/O expansion unit from Omron's CP1W series, designed to seamlessly integrate with compatible programmable logic controllers (PLCs) to enhance input and output capacity. This industrial-grade module provides reliable signal interfacing for automation systems requiring additional I/O points, making it ideal for expanding control capabilities without requiring a complete PLC upgrade. Engineered for durability and precision, this unit maintains Omron's reputation for quality in industrial automation components.

Key Features and Benefits

• Enhanced I/O Configuration: 24-point DC input (24V) and 16-point transistor output (sourcing) for flexible system expansion.
• Robust Electrical Specifications: Input operates at 24V DC with 7mA consumption per point; outputs deliver 0.5A per point (4A max per common terminal).
• Compact Industrial Design: Space-saving dimensions (90×65×75mm) with lightweight (400g) construction for easy integration into control panels.
• Efficient Power Management: Low power consumption (50mA at 5V DC from PLC, 60mA at 24V DC external) reduces system load.
• Advanced Isolation: Photocoupler isolation between I/O circuits ensures protection against electrical noise and voltage spikes.
• High-Speed Response: 1ms maximum response time for both inputs and outputs enables precise real-time control.
• Wide Voltage Tolerance: Stable operation within 20.4-26.4V DC range accommodates typical industrial power fluctuations.
• Standard Warranty: Backed by Omron's 1-year manufacturer warranty for guaranteed performance and reliability.
