Belimo PRBUP-MFT-T Actuator

The Belimo PRBUP-MFT-T is a universal voltage, non-fail-safe programmable actuator designed for high-performance valve and damper applications. Operating on a wide power supply range of 24-240V AC or 24-125V DC, this unit offers maximum field flexibility for contractors. As a direct replacement for the SY3-120MFT, it features Multi-Function Technology (MFT), allowing for precise control signal adjustment, including 2-10VDC and 4-20mA, as well as BACnet MS/TP and Modbus RTU integration. Built for demanding environments, the NEMA 4X / IP66/67 rated enclosure ensures reliable operation in wash-down or outdoor conditions. This model includes two SPDT auxiliary switches for position feedback and a 7 mm manual override crank. Note that when replacing an older SY series unit, specific linkages and valve/damper mechanical data are required to ensure proper mounting and torque transfer.

Key Benefits for the Technician

• Universal Power Compatibility: Supports 24-240V AC, reducing the need to carry multiple SKUs for different job site voltages.
• Advanced Integration: Supports BACnet, Modbus, and MP-Bus, allowing for seamless communication with modern building automation systems.
• Rugged Enclosure: The NEMA 4X / IP66/67 housing provides superior protection against corrosion, dust, and moisture.
• Field Programmable: Utilize Belimo MFT to customize running time, control signals, and feedback parameters to match specific site requirements.
• Manual Override: Includes a 7 mm hex crank for manual positioning during commissioning or maintenance.

Common Questions

Can the PRBUP-MFT-T replace an older SY3-120MFT actuator?
Yes, it is the direct replacement; however, because the mechanical footprint differs, you must use the correct mounting linkages. Always verify the valve or damper shaft dimensions before installation.

Does this unit support 4-20mA control signals?
Yes, through Multi-Function Technology (MFT), the actuator can be configured to accept a 4-20mA input signal with the addition of a 500? resistor or via software programming.

Is this actuator suitable for outdoor cooling tower applications?
Absolutely. With its NEMA 4X and IP66/67 ratings, it is specifically designed to withstand harsh outdoor conditions and moisture-heavy environments.
