Delta PLCs (Programmable Logic Controllers) are available in several types, each designed to meet different levels of automation needs — from small machines to large industrial systems. Delta has developed a wide range of PLCs that focus on performance, flexibility, and cost-effectiveness. Let’s understand the main types of Delta PLCs and what makes each one special.
The most popular and compact series is the Delta DVP Series PLC. It is widely used in small and medium automation projects. These PLCs are known for their fast processing speed, easy programming, and reliability. The DVP family includes different models such as DVP-SS2, DVP-SX2, DVP-SE, DVP-SA2, and DVP-SV2, each suited for various applications. For example, the DVP-SX2 model has built-in analog I/O for process control, while the DVP-SE model includes Ethernet communication for network-based automation. These PLCs are commonly used in packaging machines, textile systems, conveyors, and small assembly lines.
The next category is the Delta AH Series PLC, which is designed for larger and more complex automation systems. It features modular architecture, high-speed processing, and advanced networking capabilities. The AH series supports multiple communication protocols, including EtherCAT, Ethernet/IP, and Modbus TCP. It is ideal for industries such as automotive manufacturing, process control, and plant-wide automation where precision and coordination are critical.
Another type is the Delta AS Series PLC, which offers high-speed, high-performance control with powerful motion capabilities. It supports advanced functions such as multi-axis servo control, making it suitable for robotics, packaging, and precision equipment. The AS series PLCs can easily connect to Delta’s servo drives and HMIs, allowing seamless integration across the automation network.
Delta also provides the FC Series PLCs, which are specialized for HVAC, building management, and energy-saving systems. These PLCs offer efficient control for fan systems, chillers, and lighting networks with focus on energy efficiency and reliability.
