Actuator LSiS TA MC100/24 1 kN 24VAC with 3-position control, 0–10V and 4–20 mA inputs

LSiS TA MC100/24 is an electric linear actuator delivering 1 kN of thrust for valve and damper positioning in HVAC and building automation systems. Designed for 24 VAC supply, the actuator supports three-position control and analogue control via 0–10 V and 4–20 mA inputs, enabling integration with a wide range of controllers and building management systems. The device provides controlled linear movement suitable for modulating or discrete on/off positioning tasks where reliable mechanical actuation is required.

Advantages

The actuator offers multiple control options—three-position discrete control alongside two common analogue signal standards—allowing flexible interfacing with legacy and modern controllers. With a rated force of 1 kN and a compact electromechanical design for 24 VAC operation, it facilitates straightforward installation on valve spindles and damper linkages. The combination of robust linear output and standard control inputs simplifies commissioning and system integration while supporting predictable positioning performance in HVAC applications.

Suitable for

• Positioning control of heating and cooling valves
• Damper actuation in ventilation and air-handling units
• Integration with building management systems and controllers
• Retrofit projects requiring compatibility with 0–10 V or 4–20 mA signals

Key specifications

• Actuation force: 1 kN (linear thrust)
• Supply voltage: 24 VAC
• Control signals: three-position control, 0–10 V input, 4–20 mA input
• Output type: linear stroke suitable for valve spindle and damper shafts
• Interface compatibility: standard analogue and discrete control for BMS integration

How to use

Mount the actuator mechanically to the valve spindle or damper linkage following the manufacturer’s mechanical coupling instructions. Connect the 24 VAC supply to the designated power terminals and wire the control input according to the desired mode: apply discrete signals for three-position control or feed 0–10 V or 4–20 mA analogue signals for proportional positioning. Perform initial end-stop and range adjustments if required by the installation, then verify travel and response through the controller or BMS. Periodic functional checks ensure consistent positioning and detect wear or connection issues.

Usage recommendations

Use appropriate overcurrent protection and follow local electrical safety standards when connecting the 24 VAC supply. For reliable long-term operation, avoid exposure to excessive moisture or mechanical shock and verify compatibility of control signal ranges with the system controller prior to commissioning.
