The Delta DVP20SX311T is a compact yet powerful slim-line PLC from Delta’s DVP-SX3 Series, designed to deliver high-speed processing, integrated analog capabilities, and versatile communication in a space-saving form. This model features 20 built-in I/O points, including 8 digital inputs, 6 NPN transistor outputs, 4 analog inputs, and 2 analog outputs, making it ideal for applications that require both discrete and analog control. Powered by a 32-bit high-speed processor—the same core used in Delta’s advanced AS Series—it ensures ultra-fast execution speeds of approximately 25 nanoseconds per basic instruction, enabling precise and responsive control.

The DVP20SX311T supports various communication protocols through its multiple built-in ports, including Ethernet (with EtherNet/IP support), two RS-485 ports, a CANopen interface, and USB/Micro-SD for data storage and firmware updates. It also features robust motion control capabilities, such as high-speed pulse outputs, linear and arc interpolation, and multi-axis control—supporting up to eight Delta servos via CANopen. With a program capacity of up to 64K steps and support for up to 512 I/O points through expansion modules, this PLC is well-suited for advanced automation in fields such as packaging, material handling, semiconductor processing, HVAC control, and textile machinery. Its integration of analog and digital control, combined with compact design and strong networking capability, makes the DVP20SX311T an efficient and cost-effective solution for modern industrial systems.
