Information About PRBUP-MFT-T
The PRBUP-MFT-T is part of Belimo’s high-performance MFT actuator platform engineered for demanding valve control applications requiring flexibility and network integration. It supports analog, digital, and network-based control through BACnet MS/TP, Modbus RTU, and MP-Bus, allowing seamless integration into modern building automation systems. The actuator operates across a broad AC/DC voltage range and includes electronic overload protection to ensure consistent torque throughout the full stroke. Designed with a sealed IP66/67 and NEMA 4X enclosure, it is suitable for harsh mechanical and outdoor environments while remaining maintenance-free.
Key Features
- MFT Programmable Control Platform: Allows configuration for 2…10 V, 4…20 mA, on/off, or floating point control from a single actuator model.
- Wide AC And DC Voltage Operation: Supports AC 24–240 V and DC 24–125 V power supplies, reducing transformer and inventory requirements.
- Integrated Network Communication: Native BACnet MS/TP, Modbus RTU, and MP-Bus enable direct connection to building automation systems.
- Non Spring Return Operation: Maintains the last commanded valve position during power loss for stable and predictable system behavior.
- Dual Auxiliary Switches: Two SPDT switches provide configurable end-position indication and interlocking for system logic.
- Adjustable Actuation Speed: Motor runtime configurable between 30 and 120 seconds per 90° rotation to match application dynamics.
- Rugged Environmental Protection: IP66/67 and NEMA 4X enclosure ratings protect internal components from dust, moisture, and harsh conditions.
The PRBUP-MFT-T delivers the reliability and precision required for flexible, networked valve actuation in commercial and industrial HVAC systems.
