The Delta DVP28SS211R is a model of the Delta PLC (Programmable Logic Controller) series. It is a compact and cost-effective CPU module designed for various industrial automation applications. Here are some key features and specifications of the Delta DVP28SS211R:

1. Inputs and Outputs: The DVP28SS211R has 14 digital inputs and 14 digital outputs. Both the inputs and outputs can be configured as sinking or sourcing types.

2. Communication Ports: It features one built-in communication port, which is an RS232 port. This allows for easy connectivity with other devices or networks.

3. Program Capacity: The DVP28SS211R has a program capacity of 8k steps, providing ample space for developing control logic.

4. High-Speed Pulse Output: It offers two high-speed pulse output channels that support output frequencies up to 100kHz, which is useful for controlling motion devices such as stepper motors or servo drives.

5. Multiple Programming Languages: The DVP28SS211R supports multiple programming languages, including Ladder Diagram (LD) and Structured Text (ST), allowing programmers to choose their preferred programming method.

6. Expansion Modules: The PLC supports expansion modules, which can be added to increase the number of inputs and outputs or to include specialized functions such as analog I/O or temperature control.

7. Built-in Functions: The DVP28SS211R features various built-in functions such as timers, counters, data registers, mathematical functions, and communication instructions, facilitating the implementation of complex control algorithms.

8. HMI Integration: It can be easily integrated with Delta's Human Machine Interface (HMI) products, allowing operators to monitor and control the PLC system through an intuitive graphical interface.

9. Programming Software: Delta provides its own programming software, called WPLSoft, which allows users to program and configure the DVP28SS211R PLC using a PC.
