Danfoss 027H9120 | ICAD 600A Motor Actuator

Product Overview

The ICAD 600A (027H9120) is a high-precision motorized actuator designed specifically for the Danfoss ICM integrated control valve range. Engineered for excellence in industrial refrigeration, this actuator translates electronic control signals into precise mechanical positioning for valves in suction, liquid, and hot gas lines. By utilizing the Danfoss 027H9120, facility engineers can achieve unparalleled accuracy in temperature and pressure regulation, which is essential for minimizing energy consumption and preventing product loss in cold storage and food processing plants. Its advanced motor technology ensures rapid response times and high torque, maintaining system stability even under fluctuating load conditions.

Technical Configuration

The ICAD 600A (Industrial Control Actuator with Display) architecture is built around a brushless DC motor, providing superior reliability and maintenance-free operation compared to traditional brushed motors. The unit features an integrated digital display and a user-friendly interface that allows for local configuration and real-time status monitoring. It supports multiple analog input signals (0-20 mA, 4-20 mA, 0-10 V, or 2-10 V) and provides feedback via an analog output signal for remote monitoring. The 027H9120 model is specifically sized for the smaller ICM valve range (ICM 20 to ICM 32), offering high-resolution positioning that enables fine-tuned flow control in demanding B2B industrial applications.

Technical FAQs

Can the ICAD 600A be used on any ICM valve?

No, the ICAD 600A is designed specifically for ICM 20, ICM 25, and ICM 32 valves. For larger valves (ICM 40 to ICM 150), the ICAD 1200A model must be utilized to meet the higher torque requirements.

What happens to the actuator in the event of a power failure?

The ICAD 600A can be configured with a UPS (Uninterruptible Power Supply) to ensure the valve moves to a safe position (fully open or fully closed) during a power outage.

Does this actuator require manual calibration upon installation?

The ICAD 600A features an automatic calibration function. Once mounted on the ICM valve and powered up, it will perform a "calibration run" to identify the mechanical end-stops of the valve.

Engineering & Installation Guide

• Wiring and Voltage Stability: Always use a dedicated 24 VDC power supply. Ensure the voltage at the actuator terminals does not drop below 20.4 VDC during operation. Use shielded cables for the control signal (4-20 mA) to prevent electromagnetic interference from nearby heavy machinery or VFDs.

• Mounting and Orientation: The actuator is designed for universal mounting; however, it is best practice to install the ICAD with the display facing a visible direction for maintenance. Ensure the three hexagonal socket screws are tightened to the correct torque to ensure a moisture-proof seal between the actuator and the valve body.

• Moisture Prevention: In low-temperature applications where condensation is heavy, ensure the cable glands are tightened properly and pointing downwards. The IP67 rating protects against immersion, but constant exposure to ice buildup should be managed to protect the digital display membrane.
