Elfin EE11A – LAN converter RS485 ↔ Modbus TCP

🔌🌐 Elfin EE11A – RS485 → Modbus TCP (LAN)

Elfin EE11A is a converter serving as a communication bridge between devices with RS485 (Modbus RTU) interface and a superior system using Modbus TCP. It enables integration of inverters, electricity meters, wallboxes, and other third-party technologies into the SHE system, where all control logic is implemented through Quick Apps.

💼 Business presentation

Elfin EE11A is a key infrastructure element in projects requiring long-term stable and proven communication between technologies and the control system. The converter is long-term used in the SHE system and its communication is tested in real-world installations. It is suitable for installations in switchboards with available LAN network, where emphasis is placed on trouble-free and continuous operation. The converter itself does not control any technologies, but creates the necessary communication layer, without which it would not be possible to integrate technologies into the SHE system.

🧩 Role in SHE system

Elfin EE11A is a necessary component of the SHE system in cases where the connected technology does not support Modbus TCP communication. The converter is essential in particular for communication with inverters, wallboxes, the EX01 module, and other devices using the RS485 bus. Without this converter, it would not be possible to fully integrate and control these technologies using SHE QA.
