Delta DVP28SA211T PLC Controller

The Delta DVP28SA211T PLC is a second-generation, slim-type programmable logic controller (PLC) designed for enhanced performance in compact industrial applications. It features a 12-point main processing unit (MPU) with 16 digital inputs and 12 digital outputs, and supports expansion up to 492 I/O points using DVP-S series extension modules. With a program capacity of 16k steps and high-speed pulse outputs—two channels at 100 kHz and two at 10 kHz—it is well-suited for precise motion control tasks. The built-in RS-232 and dual RS-485 communication ports support Modbus ASCII/RTU protocols, allowing the PLC to function as either a master or slave device. Additionally, the DVP28SA211R PLC supports various extension modules, including analog I/O, temperature measurement, and communication modules like PROFIBUS and DeviceNet. Its compact design and versatile features make it ideal for applications such as printing machines, dyeing machines, container fillers, and workstation monitoring in production lines.
