cULus UL60730-1A/-2-14|CAN/CSA File No. E60730-1:02|CE 2014/30/EU, 2014/35/EU

BELIMO® Non-Spring Return Hydronic Actuator, 24 VAC/VDC, 50/60 Hz, 5 VA, 2.5 W Power, 90 in-lb Torque, Control Signal: Modulating, Control Type: External Push-Button, Manual, Rotation Angle: 95 deg, Input Impedance: 100 Ohm, 500 Ohm, IP66, IP67, NEMA 4X Enclosure, Rotation Type: Adjustable with Mechanical Stop, Timing Range: 95 s, Noise Level: 45 dBA, Plastic, 9.56 in W x 6.29 in H x 5.27 in D

The NMB24-SR-T N4 provides 95 deg of rotation and a visual indicator indicates position of the actuator. When reaching the damper or actuator end position, the actuator automatically stops. The gears can be manually disengaged with a button on the actuator cover. The NMB24-SR-T N4 actuator uses a sensorless brushless DC motor, which is controlled by an application specific integrated circuit (ASIC). The ASIC monitors and controls the actuator's rotation and provides a digital rotation sensing (DRS) function to prevent damage to the actuator in a stall condition. Power consumption is reduced in holding mode. Add-on auxiliary switches or feedback potentiometers are easily fastened directly onto the actuator body for signaling and switching functions. For low ambient temperatures, the optional supplemental (-H) Heater add-on is available.

Features

  • The actuator is mounted directly to a damper shaft up to 3/4 in diameter by means of its universal clamp
  • The actuator operates in response to a 2 - 10 VDC or with the addition of a 500 Ohm resistor, a 4 - 20 mA control input from an electronic controller or positioner
  • A 2 to 10 VDC feedback signal is provided for position indication or master slave applications
  • The actuator is not provided with and does not require any limit switches, but is electronically protected against overload
  • The anti-rotation strap supplied with the actuator will prevent lateral movement
