FFU et équipement de purification de l'air terminal
FFU passerelle de communication BMS
A DIN-rail industrial gateway that translates an FFU field bus into selected BACnet or Modbus points for the building management system.
- Isolated RS-485 Network
- BACnet or Modbus Mapping
- DIN-Rail Installation
- Visible Port Diagnostics
Introduction de produit
The FFU BMS communication gateway sits between an addressable fan filter network and the facility automation system. Isolated RS-485 ports connect downstream controllers, while Ethernet or a second serial interface presents mapped commands, feedback and alarm states to BACnet or Modbus. Front LEDs indicate power, communication and fault activity, and a local service port supports setup without interrupting the main network. The gateway limits the BMS to defined points rather than giving it direct electrical control of each motor.
Key Features
Galvanically isolated serial channels reduce fault propagation and ground-potential problems.
Front status LEDs distinguish network traffic, port failure and power conditions during service.
DIN-rail construction allows the gateway to share a protected low-voltage control enclosure.
Préoccupations du client produit
FFU networks and building systems often use different protocols, addressing rules and electrical references even when they need to exchange only a small set of operating points.
The BMS cannot read the proprietary or low-level serial messages used by the FFU network.The gateway translates selected fan data into standard BACnet or Modbus objects.
A ground fault on a long field bus disrupts the supervisory controller.Electrical isolation separates downstream RS-485 wiring from the building-side interface.
Technicians cannot identify whether a problem is on the FFU side or the BMS side.Independent port activity and fault LEDs show communication state for each network.
Unrestricted external commands could override cleanroom safety and operating sequences.Configurable point mapping exposes only approved setpoints, status values and alarms.
