Eaton Z-S230/4S Impulse Relay 16A 4NO 230V

The Eaton Z-S230/4S impulse relay is a robust electromechanical switching device engineered for precise control of electrical circuits. Operating at 230V with a 16A rated current, this unit features four normally open (NO) contacts, making it an essential component for modern electrical installations. It is designed to provide reliable switching operations in response to momentary control signals, ensuring long-term durability and consistent performance in both residential and commercial environments.

Advantages

This impulse relay offers significant benefits for complex lighting and automation setups. By utilizing a latching mechanism, it maintains its state without continuous power consumption on the control coil, which enhances energy efficiency and reduces heat generation within the distribution board. The four-contact configuration allows for the simultaneous control of multiple independent circuits or phases, providing flexibility in system design. Its compact modular construction ensures easy integration into standard DIN-rail mounting systems, facilitating streamlined installation and maintenance processes.

Suitable for

• Lighting control systems in residential buildings
• Automation of electrical circuits in commercial offices
• Multi-circuit switching applications
• Integration into smart building management systems

This device may not be suitable for applications requiring high-frequency switching or rapid cycling, as the mechanical nature of the relay is optimized for standard operational demands rather than continuous high-speed pulsing. It is also not intended for use in environments with extreme vibration or high levels of dust and moisture without appropriate protective enclosure.

Key specifications

• Rated current: 16A
• Control voltage: 230V AC
• Contact configuration: 4 normally open (NO) contacts
• Mounting type: DIN-rail
• Operating frequency: 50/60 Hz

To use the Eaton Z-S230/4S, the device must be mounted onto a standard 35mm DIN rail within a distribution cabinet. Connect the control circuit to the coil terminals and the load circuits to the respective contact terminals. When a momentary voltage pulse is applied to the control input, the relay switches its contacts to the closed position and remains there until the next pulse is received, which resets the contacts to the open position.

What to consider before purchase

• Verify that the control voltage matches your existing system requirements
• Ensure the total load current does not exceed the 16A rating
• Confirm available space on the DIN rail within your electrical enclosure
• Check compatibility with the intended switching load type

For optimal performance and longevity, ensure that all electrical connections are tightened to the manufacturer's specified torque settings. It is recommended to install the relay in a well-ventilated enclosure to prevent overheating during prolonged operation.
