Product Description

The Siemens 6AV3503-1DB10 is the SIMATIC OP3 compact text operator panel designed for matching early Siemens S5 and S7 series PLC control systems. It serves as a lightweight local human-machine interface, supporting real-time text data display, equipment status monitoring and on-site parameter configuration to realize direct interaction between operators and automation equipment.

This HMI adopts integrated membrane keypad and monochrome text display with compact cabinet embedded structure. It features stable serial communication capability, excellent anti-interference property and low power consumption. Widely used in traditional automation workshops, it is a mature spare part for maintenance and replacement of legacy industrial control production lines.
