Motorized Actuators DC 24V (Excluding Valve) - AD24-2TC (2-wire(Auto Return))

Product Overview

The AD12-2TC operates on DC12V (2A), while the AD24-2TC operates on DC24V (2A). Both models use a forward/reverse DC control system with a simple 2-wire connection, allowing easy installation and reduced wiring complexity.

• Max. Output Torque: 200 kgf·cm

• Operating Time (90°, No-load):

  • AD12-2TC: approx. 15 seconds

  • AD24-2TC: approx. 10 seconds

• Mechanical Life: Approx. 40,000 cycles (depending on usage conditions)

• Weight: Approx. 950 g

• Standby Power Consumption: Approx. 0.5W

The actuator closes clockwise and opens counter-clockwise (top view orientation).

Compatible Valves & Operating Conditions

The actuator is compatible with:

• Ball Valves: 32A, 40A, 50A

• Butterfly Valve: 50A wafer type

Valve Operating Conditions

Ball Valve

• Operating Temperature: 0°C to 120°C

• Application Fluid: Non-corrosive liquids and gases

Butterfly Valve

• Operating Temperature: 0°C to 90°C

• Application Fluid: Non-corrosive water and liquids

Maximum Operating Pressure: 10 kgf/cm² (142 PSI)

Electrical Connection

The actuator uses a 2-wire DC power connection:

• Red (+), Black (–) for Close

• Reverse polarity for Open

In case of power loss, the actuator defaults to the Close position, enhancing operational safety.

When powered on for the first time after installation or after a long idle period, the actuator requires approximately 3 minutes of charging before normal operation. After opening, wait at least 2 minutes before performing a closing operation to ensure stable performance and extend service life.

Visual Status Indication

The actuator is equipped with both a display window and an indicator lamp for clear status confirmation:

• When Open: A circle (○) appears and the green lamp is ON

• When Closed: A cross (×) appears and the lamp is OFF

This dual-indication system ensures easy visual monitoring in industrial environments.

Manual Override Function

For emergency situations or maintenance, the actuator includes a manual lever. By pulling the lever upward and rotating the actuator body, the valve can be manually operated.

Note:

• During manual operation, the display window and indicator lamp do not change status.

• After manual operation, the fixing pin must be returned to its original position.

Installation Guidelines

• Install the actuator vertically onto a valve already fixed in the piping line.

• Ensure correct wiring according to the connection diagram.

• Install a switch or disconnecting device for emergency power-off.

• Use an overcurrent protection device to protect the circuit.

• The actuator is designed for indoor use without condensation.

• Operating Environment: -15°C to 50°C (35–85% RH)

The actuator must not be submerged in water. Exposure to water may cause malfunction or electric shock. Storage and transportation temperature range: -25°C to 55°C.
