The Belimo SM24P-MP is a damper actuator used to modify air dampers in ventilation and air-conditioning systems.

This specific type of actuator applies a rotary motion.

The control type of the SM24P-MP is modulating.

The Torque force is 20 Nm.

Fields of application: The actuator is particularly suitable for utilisation in outdoor applications and is protected against the following weather conditions: - Wood drying - Animal breeding - Food processing - Agricultural - Swimming baths / bathrooms - Rooftop ventilation plant rooms - General outdoor applications - Changing atmosphere - Laboratories

Used materials :Actuator housing polypropylene (PP) Cable glands / hollow shaft polyamide (PA) Connecting cable FRNC Clamp / screws in general Steel 1.4404 Seals EPDM Form fit insert aluminium anodised

Mode of operation: Conventional operation: The actuator is connected with a standard modulating signal of DC 0...10V and drives to the position defined by the positioning signal. The measuring voltage U serves for the electrical display of the actuator position 0...100% and as slave control signal for other actuators. Operation on the MP-Bus: The actuator receives its digital positioning signal from the higher level controller via the MP-Bus and drives to the position defined. Connection U serves as communication interface and does not supply an analogue measuring voltage.

Converter for sensors: Connection option for a sensor (passive or active sensor or switching contact). The MP actuator serves as an analogue/digital converter for the transmission of the sensor signal via MP-Bus to the higher level system.

Parameterisable actuators: The factory settings cover the most common applications. Single parameters can be modified with the Belimo Service Tools MFT-P or ZTH EU.

Simple direct mounting Simple direct mounting on the damper spindle with an universal spindle clamp, supplied with an anti-rotation device to prevent the actuator from rotating.

Manual override: Manual override with push-button possible (the gear is disengaged for as long as the button is pressed or remains locked).

High functional reliability: The actuator is overload protected, requires no limit switches and automatically stops when the end stop is reached.

Adjustable angle of rotation: Adjustable angle of rotation with mechanical end stops. Standard setting 0 ... 90°. The housing cover must be removed to set the angle of rotation.

Home position: The first time the supply voltage is switched on, i.e. at the time of commissioning, the actuator carries out a synchronisation. The synchronisation is in the home position (0%). The actuator then moves into the position defined by the positioning signal.Adaption and synchronisation An adaption can be triggered manually by pressing the “Adaption” button or with the PC-Tool. Both mechanical end stops are detected during the adaption (entire setting range). Automatic synchronisation after pressing the gearbox disengagement button is configured. The synchronisation is in the home position (0%). The actuator then moves into the position defined by the positioning signal. A range of settings can be adapted using the PC-Tool (see MFT-P documentation)
