OEMAX NX-AI8C 8-Channel Analog Input Module

The OEMAX NX-AI8C is a high-performance 8-channel analog input module designed for the OEMAX NX Series programmable logic controller (PLC) system. It serves as a critical component for acquiring analog signals from field devices such as pressure sensors, temperature transmitters, flow meters, and other 4-20 mA instruments. The module converts these analog signals into digital values that the PLC CPU can process, enabling precise monitoring and control in industrial automation applications.

High-Accuracy Analog Conversion

The NX-AI8C provides high-speed and high-accuracy conversion speed and resolution, which are the deciding factors for the performance of an analog unit. This allows for a wider input range, faster conversion speed, and higher resolution, making it ideal for applications that demand precise signal acquisition. The module features DC/DC converter and/or photocoupler isolation between the input channels and the internal circuit, ensuring reliable operation in electrically noisy industrial environments.

System Integration

As part of the OEMAX NX Series I/O system, the NX-AI8C integrates seamlessly with the NX-CPU700P processor module and other NX Series I/O modules. It connects to the system backplane (such as the NX-BASE10) and communicates with the CPU via the high-speed NX bus. The module is ideal for a wide range of applications, including temperature, speed, pressure, and flow measurements, as well as electric measurements such as voltage, current, power, and frequency.

Application Domains

Typical applications include process monitoring in manufacturing lines, data acquisition for quality control, and analog signal integration for SCADA systems. The NX-AI8C is also widely used in packaging machinery, textile equipment, and small-scale process automation where reliable analog input acquisition is required.
