A Complete Guide to Delta PLC Models: From DVP to AX-5
Delta offers a rich and diverse PLC product line, categorized into multiple series based on product positioning and performance levels. Below is a detailed classification of Delta's PLC series:
1. Classification by Performance Level
Entry-Level / Economy PLCs
DVP-EC/EC3 Series: Ideal for standalone single-machine control. Features built-in RS-232/485 communication, making it perfect for small-scale automation equipment.
DVP-SS Series: Slim, economy main units designed to meet basic control requirements.
Standard PLCs
DVP-ES/ES2 Series: Comprehensive standard main units with I/O options ranging from 16 to 80 points.
DVP-EX/EX2 Series: Standard/analog hybrid main units featuring built-in multi-channel analog inputs/outputs.
Functional / Enhanced PLCs
DVP-EH/EH2/EH3 Series: High-performance enhanced PLCs equipped with a rich variety of modules and expansion cards.
DVP-SV/SV2 Series: High-performance slim main units offering superior network communication capabilities.
DVP-SX/SX2 Series: Slim and compact PLCs that, in addition to digital I/O, feature built-in multi-channel analog inputs/outputs.
High-End / High-Performance PLCs
AS Series (AS100/AS200/AS300): High-performance general-purpose controllers.
AH Series: High-end modular controllers.
AX-5 Series: Advanced modular controllers.
2. Main Models in the AS Series
The AS Series is divided into three sub-series: AS100, AS200, and AS300. Key CPU models include:
AS132T-A / AS132P-A / AS132R-A: 32-point main units
AS148T-A / AS148P-A / AS148R-A: 48-point main units
AS164T-A / AS164P-A / AS164R-A: 64-point main units
AS228T-A / AS228P-A / AS228R-A: 28-point main units
AS332T-A / AS332P-A: 32-point main units
AS324MT-A: 16DI main units
3. DVP Series Model Naming Convention
The suffix letters in Delta DVP Series models indicate the output type:
R: Relay output. Suitable for controlling inductive loads such as contactors, light bulbs, and small motors.
T: Transistor output. Ideal for high-frequency pulse control applications (e.g., stepper motors, solenoid valves).
S: Solid-state relay (SSR) output.
