Detailed Description:
-
High-Precision Multi-Channel Input: The module offers 8 differential input channels. Each channel can be independently configured to measure voltage signals (e.g., 0-5V, 1-5V, ±10V) or current signals (e.g., 4-20mA, 0-20mA). High resolution (e.g., 16-bit) ensures high accuracy in data acquisition.
-
Flexible Configuration and High-Speed Conversion: The range and signal type for each channel can be easily set via PLC programming software (e.g., CX-Programmer) or DIP switches/rotary switches on the module. It employs a high-speed A/D converter with a short total conversion time for all channels, meeting the demands of fast control systems.
-
Excellent Noise Immunity: Designed to comply with stringent industrial standards, the module features outstanding noise rejection, ensuring stable and reliable measurement data even in electrically noisy industrial sites. High voltage isolation between channels prevents mutual interference.
-
Convenient Diagnostics and Maintenance: The module is equipped with LED status indicators (e.g., RUN, ERC, ADJ) for intuitive display of operation status, errors, and adjustment mode. It supports wire break detection (for 4-20mA inputs), generating an alarm when the input current falls below a set threshold, facilitating quick troubleshooting of sensor faults.
-
Seamless System Integration: As an expansion unit for the CJ Series PLC, it can be mounted directly on the CPU rack or extension rack. It communicates with the CPU via the backplane bus for high-speed data exchange, requiring no additional wiring, enabling the construction of compact and reliable systems.
