Product Overview

The OMRON CJ1W-PH41U is a versatile and high-performance universal input unit designed for the CJ/NJ Series controllers. This unit is part of the CJ-series Special I/O Units, offering four isolated input channels that can be configured for a wide range of sensor types, including platinum resistance thermometers (Pt100, JPt100, Pt1000), thermocouples (K, J, T, E, L, U, N, R, S, B, WRe5-26, PLII), and DC current/voltage signals (4 to 20 mA, 0 to 20 mA, 1 to 5 V, etc.).

Key Features

• Versatility: Supports multiple input types, allowing users to tailor each channel to their specific needs without needing multiple units.
• High Resolution: Offers resolutions up to 1/256,000 with a conversion period of 60 ms for precise data acquisition.
• Isolation: Ensures electrical isolation between inputs and the CPU unit, reducing interference and enhancing reliability.
• Advanced Alarms: Features process value alarms with customizable settings for upper and lower limits, as well as rate-of-change alarms for monitoring dynamic changes.
• User-Friendly Configuration: Input type, range, and scaling are settable for each channel, providing flexibility in system design and integration.
• Compatibility: Mountable on CPU Racks or Expansion Racks, making it easy to integrate into existing control systems.
• Safety Standards: Compliant with various international standards for resistance thermometers and thermocouples, ensuring reliability in industrial environments.
