Delta PLC Selection – Practical Guide
This article provides a practical guide to Delta PLC selection, helping you make the right selection decisions quickly in real projects.
I. Pre-Selection Preparation
1. Define Control Requirements
How many input points (sensors, buttons, switches) need control?
How many output points (motors, valves, indicators) need control?
Are analog inputs (temperature, pressure, flow) required?
Are analog outputs (drive speed control, proportional valves) required?
2. Evaluate Performance Requirements
High-speed counting required? (encoders, flow meters)
High-speed pulse output required? (stepper motors, servos)
Motion control required? (interpolation, electronic cam)
PID control required? (temperature control, pressure control)
3. Determine Communication Requirements
Communication with host system? (Ethernet, RS-485)
Communication protocols with field devices? (Modbus, CANopen, EtherCAT)
II. Selection Decision Matrix
III. Post-Selection Validation
Confirm selected model has sufficient expansion margin
Confirm programming software supports selected model
Confirm supply lead time meets project requirements
