Belimo Actuator 2-10V 24VAC/DC 2Nm IP40 90s TR24-SR

This Belimo electrical actuator is designed for controlling quarter turn valves. The actuator delivers a torque of 2 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 modulating actuator is requires a 2-10 V input and offers position feedback, ensuring precise control over its operation and accurate monitoring of its position within the designated voltage range. The actuator has a durable plastic housing and has an IP40 protection rating. This actuator can operate within ambient temperatures between -7 and 50 °C (19 and 122 °F). The actuator comes with a 1-meter power cable.

To manually change the position, press and hold the override button, then turn the lever. The actuator automatically switches off when end stops are reached, with a pulse duration of ≥0.5 s. 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 can be controlled with a standard control signal of 2-10 V and moves to the position dictated by the control signal. Voltage measurement is employed both for visually displaying the valve position within the 0.5% to 100% range and as a control signal for other actuators. The rotation angle can be adjusted with mechanical end stops.

Pros:

• Modulating actuator with a control signal of 2-10 V
• Manual override
• Visual position indicator

Cons:

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