Belimo Analog Actuators for Dampers
Belimo analog actuators are designed for precise control of dampers with an analog control signal of 0-10V. These actuators offer a customizable operating range and a module that converts a 0-10V voltage signal to a 4-20 mA current signal. With a torque of 20 Nm, these actuators are suitable for dampers up to 4 m² and come equipped with a spring return function for enhanced safety.Electrical DataThe actuators operate at a nominal voltage of AC/DC 24 V with a frequency of 50/60 Hz. They have a working range of AC 19.2...28.8 V / DC 21.6...28.8 V, a power consumption of 5 W during operation, and 3 W in standby mode. The actuators feature a 1 m power/control cable with 4x 0.75 mm² wires and support parallel operation.Functional DataThe actuators provide a torque of 20 Nm for both motor and safety functions, with an operating range of 2...10 V and an input impedance of 100 kΩ. They offer a feedback signal of 2...10 V with a maximum measurement voltage of 0.5 mA and a positioning tolerance of ±5%. The direction of movement can be selected via a switch, and manual adjustment is possible using a crank and locking switch. The actuators have a maximum rotation angle of 95°, adjustable from 33% in 2.5% steps, and a motor running time of 150 s/90°, with a safety function running time of <20 s at -20...50°C or <60 s at -30°C. The acoustic power level is 40 dB(A).Mechanical InterfaceThe actuators feature a universal clamp for 10...25.4 mm shafts and a mechanical position indicator. They are designed for a minimum of 60,000 safe positions.Safety DataThe actuators comply with IEC/EN III protection class, SELV low voltage, and UL Class 2 supply standards. They have an IP54 enclosure rating, NEMA 2 enclosure rating, and CE marking in accordance with 2014/30/EU. They are certified to IEC/EN 60730-1 and IEC/EN 60730-2-14 standards, and UL approved according to UL60730-1A, UL 60730-2-14, and CAN/CSA E60730-1. The actuators are designed for hygienic applications according to VDI 6022 Part 1 / SWKI VA 104-01, suitable for washing and disinfection, and low-emission.Environmental DataThe actuators are resistant to impulse voltages up to 0.8 kV, have a pollution degree of 3, and can operate in environments with up to 95% relative humidity without condensation. They have an operating temperature range of -30...50°C and a storage temperature range of -40...80°C.
