Omron MY4ZN 220/240VAC (S) Miniature Power Relay

The Omron MY4ZN 220/240VAC (S) miniature power relay is developed for industrial control systems that require reliable switching performance together with multiple changeover contacts. As part of the Omron MY relay series, this compact plug-in relay is frequently used in automation panels, machine interfaces, process control systems, and auxiliary switching applications.

Its 220/240VAC operating coil makes it suitable for industrial environments where AC control voltage is commonly used. Combined with a 4PDT contact arrangement and bifurcated contacts, the relay supports dependable operation across a wide range of industrial switching tasks.

Technical Features of the Omron MY4ZN 220/240VAC (S) Miniature Power Relay

The relay contains four independent changeover contacts that switch simultaneously when the coil is energized. This 4PDT structure allows engineers to control several circuits from one relay action while maintaining electrical separation between outputs.

Bifurcated contacts are designed to improve switching reliability in low-level signal applications. By dividing the contact surface into dual contact points, the relay can provide more stable electrical continuity during operation.

The relay also includes LED indication and mechanical operation indication, allowing technicians to quickly confirm switching status during maintenance or troubleshooting procedures.

Its plug-in socket mounting configuration simplifies installation and replacement. In industrial environments where maintenance efficiency matters, plug-in relays can help reduce downtime and service complexity.

Industrial Automation Applications

The Omron MY4ZN 220/240VAC (S) miniature power relay is commonly integrated into industrial automation panels, HVAC control systems, packaging machinery, conveyor controls, alarm systems, and machine interlock circuits.

Many engineers use this relay when multiple control outputs are required within a compact panel layout. Since the relay provides four independent contact sets, it can support signal routing, auxiliary control logic, interface switching, and process sequencing.

The relay is also suitable for use in control cabinets that rely on standard 220/240VAC control voltage infrastructure. Its compact dimensions help optimize panel space while maintaining flexible switching capability.
