Belimo Actuator 24VAC/DC 10Nm KNX IP54 90s NR24A-KNX

This Belimo electrical actuator is designed for controlling quarter turn valves. The actuator delivers a torque of 10 Nm and can open/close the valve in 90 seconds. This actuator requires a supply voltage of 24 V AC/DC and has a visual positioning indicator to clearly see the valve position. The actuator is equipped with KNX (S-Mode) control, allowing for seamless integration and efficient management of connected devices in the system. The actuator has a durable plastic housing and has an IP54 protection rating. This actuator can operate within ambient temperatures between 0 and 50 °C (32 and 122 °F). The actuator comes with a 1-meter power cable.

The actuator is equipped with overload protection, the actuator doesn't need limit switches and will stop automatically when the end stop is reached. Manual override is possible using a push-button, which disengages the gear train as long as the button is pressed or remains locked. The actuator can be directly mounted on the ball valve using a single screw. The mounting orientation relative to the ball valve can be chosen in 90° increments. The actuator is equipped with an integrated interface for KNX (S-Mode) and can connect with all KNX devices with available corresponding data points. The KNX application enables the use of the valve actuator with 2- and 3-way valves with one set point, as well as with 6-way valves in 4-pipe systems with two set points for heating and cooling. The rotation angle can be adjusted with mechanical end stops.

Pros:

• Manual override
• The actuator is overload protected
• Visual position indicator

Cons:

• The time to open/close of 90 s is slow for some applications
