Delta HMI (Human Machine Interface) refers to the operator interface products developed by Delta Electronics, a major global manufacturer of industrial automation products. Delta HMIs are used to monitor and control machinery and processes in industrial environments, providing a visual interface between the user and machines (such as PLCs, drives, sensors, etc.).
Here’s a detailed breakdown of Delta HMI:
🔹 1. Basic Overview
Delta HMIs are touchscreen panels that:
Display process data from controllers like PLCs.
Allow operators to input commands.
Monitor alarms and status.
Log data and trends.
🔹 2. Popular Delta HMI Series
Delta offers several HMI product lines, primarily:
DOP Series (Delta Operator Panel)
DOP-B Series: Basic models, cost-effective, suitable for standard applications.
DOP-W Series: Wide-screen models with better resolution and multitouch.
DOP-H Series: High-end models with better performance and enhanced features.
🔹 3. Key Features
Touchscreen Operation (4.3” to 15” sizes, depending on the model).
High-resolution displays (TFT LCD).
Multiple communication ports: RS232/RS485/RS422, Ethernet, USB.
Multi-language support.
Data Logging and Recipe Handling.
Alarming System: Display and log alerts.
Built-in real-time clock (RTC).
Built-in memory and SD card/USB for storage.
Connectivity to over 30 brands of PLCs and automation devices.
🔹 4. Supported Protocols
Delta HMIs support a wide range of industrial communication protocols:
