CP1W-40EDR Omron PLC Expansion Module 24 Digital I/O Points

2. Key Selling Points

1. 6 Core Selling Points of the Omron CP1W-40EDR

   1. 24-Point Digital I/O Expansion Module
      Provides 24 digital I/O points in a compact, space-saving design:

      • 16 DC Input Points (24 VDC sink/NPN type)
      • 8 Relay Output Points (SPDT contacts)
        Ideal for expanding the control capacity of small to mid-sized automation systems.

   2. Universal Relay Outputs for AC & DC Loads
      Features 8 mechanical relay outputs that can switch both AC and DC loads (up to 250 VAC or 30 VDC, 2 A per point), making it highly versatile for controlling devices like contactors, lamps, solenoids, motors, and heaters—regardless of power type.

   3. SPDT (Form C) Contacts for Flexible Control
      Each output is a Single Pole Double Throw (SPDT) relay with Normally Open (NO) and Normally Closed (NC) contacts—enabling flexible circuit design for applications requiring fail-safe logic, alternate switching, or redundant control paths.

   4. Noise-Filtered DC Inputs for Stable Signal Detection
      Includes 16 sink-type (NPN) 24 VDC inputs with built-in digital filtering to suppress electrical noise, contact bounce, and interference—ensuring reliable and stable signal acquisition from sensors, push buttons, and limit switches.

   5. Direct CPU Integration – Bus-Powered Operation
      Connects directly to CP1E, CP2E, CP1L, or CP1H CPU units via the backplane and is powered entirely from the CPU’s internal bus—no external power supply required—simplifying wiring, reducing panel space, and lowering installation cost.

   6. Modular & Scalable System Design
      Part of Omron’s CP1W modular expansion system, allowing seamless integration with other CP1W-series modules (e.g., analog, communication, high-speed counters)—enabling flexible and future-proof automation solutions.
