AS228T-A AS200 Series Mid-Range PLC 16DI/12DO NPN Ethernet | Delta

The Original New Delta AS228T-A is a 28-point mid-range PLC CPU module from the AS200 series, engineered for high-speed automation across electronics manufacturing, food packaging, labelling, and textile machinery applications. Powered by a 32-bit SoC CPU, it achieves a basic LD instruction execution speed of 25 ns and MOV operations in approximately 0.15 µs. The module provides 16 digital inputs and 12 NPN transistor outputs, with program capacity of 64k steps and data register capacity of approximately 60k words. Featuring a built-in 10/100 Mbps Ethernet port, dual RS-485 ports, CANopen, and Mini USB, the AS228T-A supports Modbus TCP, EtherNet/IP, and Modbus RTU/ASCII communication protocols. Its compact modular design supports up to 32 extension modules for a maximum of 1,024 I/O points, with 6-axis 200 kHz pulse output and 4-channel 200 kHz high-speed counter for motion and positioning control.
