Delta PLCs (Programmable Logic Controllers)—covering what they are, types, features, applications, and more.
🔹 What is a Delta PLC?
A Delta PLC is an industrial control system developed by Delta Electronics, designed to automate machinery and processes. It's widely used in manufacturing, processing, and other industrial environments for precise control and automation.
🔹 Key Features of Delta PLCs
✅ Modular Design – Flexible I/O expansions
✅ High-Speed Processing
✅ Reliable & Rugged – Industrial-grade durability
✅ Multiple Communication Ports – RS-232, RS-485, Ethernet, CANopen, MODBUS, etc.
✅ Support for HMI & SCADA Integration
✅ Programmable with WPLSoft / ISPSoft (Delta software)
🔹 Main Delta PLC Series
Here’s a breakdown of the popular Delta PLC families:
🟠 DVP Series – Most common
DVP-SS2: Basic and cost-effective. Good for simple automation.
DVP-SA2: Advanced with more I/O and better speed.
DVP-SX2: Built-in analog I/O, ideal for process control.
DVP-ES2: High-speed with multiple extension modules.
DVP-SE: Built-in Ethernet for networking.
DVP-EH3: High performance, large program memory.
🔵 AS Series
