Eaton Z-S24/SO Impulse Relay 16A 12V DC 24V AC 1NO 1NC

The Eaton Z-S24/SO impulse relay is a robust electromechanical switching device engineered for precise control of electrical circuits. Designed to handle a rated current of 16A, this relay provides reliable operation for various automation and lighting applications. It is compatible with 12V DC or 24V AC control voltages, offering flexibility for different low-voltage installation requirements. The unit is equipped with one normally open (NO) and one normally closed (NC) contact, allowing for versatile switching configurations in residential and commercial electrical systems.

Advantages

This impulse relay stands out due to its high switching reliability and compact design, which facilitates easy integration into standard distribution boards. The dual-contact configuration provides significant flexibility for complex control logic, enabling both standard and inverted switching operations. Its ability to operate on both AC and DC control voltages makes it a versatile component for modern electrical installations, reducing the need for multiple specialized relays. The durable construction ensures long-term performance even in demanding environments.

Suitable for

• Lighting control systems in residential buildings
• Automation tasks in commercial installations
• Remote switching of electrical loads
• Integration into low-voltage control circuits

This relay may not be suitable for high-power industrial motor starting or applications requiring frequent high-speed switching beyond its mechanical design limits. It is also not intended for use in environments with extreme moisture or corrosive atmospheres without appropriate protective housing.

Key specifications

• Rated current: 16A
• Control voltage: 12V DC or 24V AC
• Contact configuration: 1 normally open (NO) and 1 normally closed (NC)
• Mounting type: DIN rail

The device is installed on a standard DIN rail within an electrical distribution board. Wiring should be performed by a qualified professional, ensuring that the control circuit voltage matches the relay specifications and that the load current does not exceed the 16A rating. Once connected, the relay responds to momentary pulses, toggling the state of the contacts to control the connected load.

What to consider before purchase

• Verify that your control circuit voltage matches the 12V DC or 24V AC requirement
• Ensure the load current does not exceed 16A
• Check available space on the DIN rail within your distribution board
• Confirm that the 1NO/1NC contact configuration meets your specific circuit design needs

Usage recommendations: Always ensure the power supply is disconnected before installation. Regularly inspect the connections for tightness and ensure the relay is kept free from dust and debris to maintain optimal switching performance.
