Ürün tanıtımı

This controller uses Modbus RTU over RS485 to send speed commands and return fan status and fault history. Addressing can be manual or use DCI auto-addressing where supported by the fan platform. It is intended for large FFU networks that require central commissioning and continuous operating visibility.

Ana Özellikler

Bidirectional communication

The network carries commands and operating feedback rather than a setpoint alone.

Network commissioning

Addressing identifies each FFU for central supervision.

Fault traceability

History data helps locate recurring fan problems.

Applications

Designed for large cleanroom fan networks needing central commissioning, continuous monitoring and device-level diagnostics. Topology and termination should follow the selected fan platform.

Solutions for Your Application

Analog control provides no device status or fault detail.Use Modbus RTU for command and readback on the same RS485 network.

Manual identification becomes difficult across many FFUs.Apply planned addresses or supported DCI auto-addressing during commissioning.

Mevcut Seçenekler

Define fan count, addressing method, baud settings, network topology, software and gateway connection. Confirm compatibility with the exact EC platform.
