Technical details and manufacturing context for Humidity Control Module

Definition

The Humidity Control Module is an integral part of an Environmental Control System designed to precisely monitor, adjust, and stabilize the moisture content in the air of a defined space. It works in conjunction with other system components (like temperature controllers and air handlers) to create and maintain optimal environmental conditions required for specific industrial processes, product storage, or operational safety. The module is typically housed in a corrosion-resistant stainless steel enclosure (grade 316L per ASTM A240) with a polycarbonate sensor cover, and it contains electronic components such as a PCB, humidity sensor, and relays. It operates within a humidity control range of 20–90 % RH with a control accuracy of ±3 % RH at steady state. The response time to reach 90% of setpoint is ≤10 seconds. It requires a 24 V DC supply voltage (reverse polarity protected, ±10%) and consumes ≤5 W at nominal voltage. The operating temperature range is -10 to 60 °C, and the operating pressure range is 1.0–1.6 MPa. The ingress protection rating is IP54–IP65 depending on enclosure option (per IEC 60529). The weight ranges from 1.2 to 1.8 kg depending on configuration. These parameters are directory reference ranges and must be confirmed for the specific model and application with the legal manufacturer or supplier. The module is a component, not a standalone system, and its performance is influenced by the overall system design and installation conditions.

Working Principle

The module typically operates by using a humidity sensor to measure the current relative humidity (RH) in the environment. This data is processed by a controller. If the RH deviates from the setpoint, the controller activates an actuator. To increase humidity, it may trigger a humidifier (e.g., ultrasonic, steam). To decrease humidity, it may activate a dehumidifier (e.g., refrigerant-based, desiccant) or coordinate with the system's ventilation to introduce drier air. It continuously cycles to maintain the target humidity range.

Frequently Asked Questions

What is the operating humidity range of the Humidity Control Module?

The directory lists a humidity control range of 20–90 % RH. This is a reference range; the exact range for a specific model must be confirmed with the manufacturer.

What supply voltage does the module require?

The module requires a 24 V DC supply voltage with a tolerance of ±10%, and it is reverse polarity protected. Always verify the voltage requirements for the specific model.

What is the ingress protection rating?

The ingress protection rating is IP54–IP65 depending on the enclosure option, per IEC 60529. Confirm the rating for the chosen configuration.

Is the module certified to any standards?

The directory lists standards such as IEC 60529 for ingress protection, but these are reference standards for verification. The module's compliance must be confirmed with the manufacturer.
