How to Select Delta PLCs?

A 5-Step Method for Precision Decision-Making

Correct PLC selection is critical to automation project success. Below is a systematic 5-step method for Delta PLC selection.

Step 1: Determine Control Scale (I/O Count)
Calculate required input/output points including DI, DO, AI, AO. Reserve 20%-30% expansion margin.

Step 2: Evaluate Processing Speed Requirements

• High-speed applications (multi-axis motion, high-speed positioning): Choose AS series (40k steps/ms) or SV3 series (25ns)

• Standard applications (sequence control, logic operations): Choose DVP-ES2/ES3 series

• Complex motion control: Choose PM series (microsecond computation)

Step 3: Determine Communication Protocols
Delta PLCs support multiple protocols: Modbus/Modbus TCP, CANopen, EtherCAT, Ethernet/IP, etc.. Determine required protocols based on host systems and field devices.

Step 4: Choose Output Type

• Relay output (R) : Suitable for inductive loads like contactors and solenoid valves

• Transistor output (T) : Suitable for high-frequency pulse control like stepper motors and servo drives

Step 5: Utilize Selection Tools
Delta offers DIASelector online selection tool and DIAStudio platform for integrated product selection, PLC programming, and parameter setting on a single platform.
