Built with four isolated input channels, each can be independently configured for a wide range of signal types such as thermocouples, Pt100 resistance thermometers, DC current and voltage, and potentiometer signals. The high 18-bit resolution ensures fine measurement granularity and improved accuracy for process control applications. Its screw-terminal connection and isolated circuitry support reliable and noise-resistant operation in industrial environments. Key Features: Universal Analog Inputs: Accepts multiple signal types including thermocouple, DC mA/V, Pt100, and potentiometers on each channel. High Resolution: 18-bit ADC resolution for precise analog-to-digital conversion. Four Independent Channels: Each input channel is configurable for different sensor and signal types. Isolated Inputs: Electrical isolation between channels enhances noise immunity and measurement stability. Screw Terminal I/O: Robust screw terminal connection for secure wiring in industrial panels. CJ-Series Compatibility: Designed for CJ and compatible NJ PLC racks and expansion racks. Wide Input Range: Supports ±100 mV to ±10 V, 0–20 mA, 4–20 mA and temperature sensor ranges. The CJ1W-PH41U delivers the reliability and precision required for high-performance analog input measurement in PLC-based control systems.
