The Delta AS218PX-A is a compact modular mid-range PLC CPU module from the AS200 Series, designed for high-performance industrial automation and control applications. It features a 32-bit SoC processor with enhanced execution speed of 40,000 steps per millisecond and basic instruction cycle time of 25 nanoseconds. The module includes 8 digital inputs, 6 PNP transistor outputs, 2 analog inputs, and 2 analog outputs, supporting a program capacity of 64,000 steps and 64,000 words of data memory. Built-in communication interfaces include USB, Ethernet (supporting Modbus TCP and EtherNet/IP), dual RS-485 ports, CANopen, and a micro SD card slot for backup and configuration. The controller supports expansion up to 32 modules or 1,024 I/O points, and provides positioning control for up to 8 axes via CANopen motion network and 6 axes via pulse control at 200 kHz. It is widely used in electronics manufacturing, labeling, food packaging, textile machinery, and diverse automated equipment.
