OEMAX NX-CPU700P Programmable Logic Controller

The OEMAX NX-CPU700P is a compact, high-performance programmable logic controller (PLC) designed for small to medium-scale industrial automation applications. It features an integrated CPU, power supply, and 16 built-in I/O points in a single compact housing, eliminating the need for additional modules in basic control tasks. The NX-CPU700P is a cost-effective, drop-in compatible alternative to the Omron CP1H series, offering seamless migration for existing systems.

High-Speed Processing and Memory

The NX-CPU700P incorporates a high-speed ASIC processor that executes basic instructions at 0.2 µs per step, ensuring fast response times for time-critical control tasks. The 20K-word user program memory provides ample space for complex control logic, while the built-in flash EEPROM retains programs without battery backup, eliminating the risk of program loss due to battery failure. Runtime editing allows users to modify instructions while the PLC is operating, reducing downtime during program adjustments.

Integrated I/O and Communication

The controller integrates 16 built-in I/O points (typically 8 digital inputs and 8 digital outputs), supporting both NPN and PNP configurations for compatibility with various sensor types. The RS-232 and RS-485 communication ports support Modbus RTU and Modbus ASCII protocols, enabling easy connection to HMIs, frequency inverters, smart instruments, and SCADA systems. For larger applications, the NX-CPU700P can be mounted on an NX-BASE series backplane to expand I/O capacity using a wide range of NX Series digital and analog I/O modules.

Built-In Real-Time Clock and Self-Diagnostics

The built-in real-time clock (RTC) enables time-stamped event logging and scheduled control tasks based on date and time, essential for data logging and maintenance scheduling. The self-diagnostics function continuously monitors the CPU and I/O modules for errors, maximizing diagnostic efficiency and minimizing system downtime. Front panel LEDs provide visual status indicators for power, run, error, and individual I/O points.

Application Domains

The NX-CPU700P is ideal for small to medium-scale automation applications, including packaging machinery, textile equipment, conveyor systems, injection molding machine auxiliary control, small process control skids, and OEM equipment requiring a cost-effective, reliable PLC solution. Its compatibility with Omron CP1H programs makes it a popular choice for system upgrades and cost reduction initiatives.
