Delta Electronics is a global leader in power and thermal management solutions. One of its key automation products is the Delta Temperature Controller, designed to maintain precise temperature control in industrial applications. These controllers are known for their accuracy, reliability, and easy integration into various process control systems.
Types of Delta Temperature Controllers
Delta offers several series of temperature controllers, each catering to specific needs:
DT B Series – Basic and economical model
DT D Series – Advanced series with PID and fuzzy control
DT E Series – Compact design, suitable for small control panels
DTA Series – High-speed response and high accuracy
DTD Series – Dual output with advanced PID tuning
DTV Series – Multi-loop temperature control for complex systems
Key Features
PID and Fuzzy Control Algorithms
Delta controllers use self-tuning PID algorithms and fuzzy logic to minimize overshoot and ensure stable performance.
Multiple Input Types
Supports thermocouples (K, J, T, etc.), RTDs (Pt100), and analog input (0–10V, 4–20mA).
Multiple Output Options
Includes relay output, SSR (Solid State Relay) output, and analog output (for controlling heaters, chillers, etc.).
High Accuracy & Fast Sampling
High-speed A/D conversion rate (up to 0.1 sec) ensures faster and more precise control.
Compact Size
Ideal for space-constrained control panels or equipment.
Easy-to-Use Interface
Digital LED/LCD displays, user-friendly buttons, and easy parameter setting.
Communication Support
Models support RS-485 communication using MODBUS RTU protocol, making them easy to integrate into SCADA or PLC systems.
Auto-Tuning Function
Automatically calculates the optimal PID parameters, reducing setup time.
