A Delta PLC is a compact, programmable device used to automate electromechanical processes. It receives inputs from sensors or devices, processes the logic based on a user-defined program, and sends outputs to actuators (motors, valves, etc.).
📦 2. Delta PLC Series Overview
Delta offers several PLC series, each suited to different applications:
✅ DVP Series
The most widely used Delta PLCs. Known for being compact, cost-effective, and reliable.
DVP-SS2: Entry-level, basic control.
DVP-SX2: With analog I/O and built-in functions (PID, high-speed counters).
DVP-SE: Ethernet communication enabled.
DVP-EH3: High performance, multi-function PLC.
DVP-SA2: Mid-range model with good speed and memory.
✅ AH Series
Modular, high-performance PLCs for complex and large-scale automation tasks.
Supports multiple CPUs, hot swapping, and extensive I/O modules.
Suitable for process control, machine automation, and motion control.
🔌 3. Inputs and Outputs
Delta PLCs support:
Digital Inputs/Outputs (DI/DO): ON/OFF signals (e.g., switches, lights).
Analog Inputs/Outputs (AI/AO): Voltage or current signals (e.g., temperature, pressure sensors).
High-speed counters, pulse outputs, PWM, and communication ports.
🌐 4. Communication Features
Delta PLCs support various industrial communication protocols:
RS-232/RS-485
Ethernet/IP, Modbus TCP/RTU
CANopen
Profibus (via modules)
BACnet (for building automation)
These allow integration with HMIs, SCADA systems, and other controllers.
🛠️ 5. Programming Software: WPLSoft / ISPSoft
WPLSoft: For older DVP series PLCs. Ladder diagram programming.
ISPSoft: Advanced software for AH and newer DVP models.
Supports Ladder, Function Block Diagram (FBD), and Structured Text (ST).
Simulation and debugging tools included.
