Aiming to break the monopoly of欧美 (Western countries) and build an independently controllable industrial field layer, the ER20 series focuses on open connectivity, ultimate reliability, and intelligent operation & maintenance. The modules are fully compatible with mainstream protocols such as EtherCAT, PROFINET, EtherNet/IP, Modbus/TCP, and CC‑Link, enabling seamless integration with various systems.

All ports feature 24V misconnection protection. The pluggable terminals and hot‑swappable design support quick maintenance and automatic reconnection. With up to 32 modules in a network, the fastest cycle time is 0.6 ms, meeting high‑speed, high‑precision real‑time control requirements. Additionally, remote firmware upgrades via the host computer are supported, endowing the product with continuous evolution capability.

The ER20 series has been widely used in high‑end scenarios such as new energy battery production lines and semiconductor equipment. It is now deeply integrating TSN and AI technologies, striving to create a domestic I/O solution that surpasses international brands and solidifies the foundation of intelligent manufacturing at the field level.
