- Communication Protocol: Supports standard protocols such as Foundation Fieldbus (FF) or Profibus.
- Operating Voltage: 24V DC.
Functional Features
- Protocol Conversion: Converts DCS internal communication protocols into fieldbus protocols.
- Device Management: Supports parameter reading, diagnostics, and configuration of field devices.
- Redundancy Support: Supports bus redundancy to improve communication reliability.
Application Scenarios
Suitable for highly automated modern factories, especially occasions requiring a large number of smart transmitters and actuators.
Performance Parameters
- Bus Speed: Supports high-speed and low-speed fieldbus standards.
- Node Capacity: A single module supports mounting multiple fieldbus devices.
Material Composition
High-strength flame-retardant plastic housing, internal circuits feature surge protection.
Structural Characteristics
- Interface: Equipped with dedicated fieldbus connectors and power terminals.
- Size: Standard FBM size, compatible with existing cabinets.
Working Principle
FBM227 periodically scans devices on the fieldbus, reads process variables and device status, packs this information, and sends it to the DCS controller. Simultaneously, it receives output commands from the controller and writes them to the actuators of field devices.
Installation Requirements
Fieldbus cables must use dedicated shielded cables and be wired strictly according to the bus topology (e.g., daisy-chain).
Precautions for Use
Bus termination resistors must be configured correctly to avoid signal reflection causing communication interruption.
