• Control Boards (Mainboards):
Act as the central processing unit of the dispenser, managing data flow, transaction control, and system logic.
• Display Modules:
Include LED or LCD screens for showing volume, price, and unit rate. Available in single or dual-display formats.
• Keypads & Input Panels:
Used for user input, preset fueling amounts, and system configuration.
• IC Card Readers & Payment Terminals:
Enable secure, contactless, or card-based transactions in modern fuel stations.
• Communication Modules (RS-485, Ethernet, Wi-Fi, 4G):
Facilitate data exchange with POS systems, station controllers, or remote monitoring platforms.
 
2. By Interface Type:
• Analog Signal Modules:
Traditional signal-based control for basic operations and legacy systems.
• Digital & Smart Interfaces:
Use protocols like RS-232, RS-485, or TCP/IP for reliable communication and remote diagnostics.
