BELIMO® NMX24-SR-T N4 1027522

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.

• 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
