Omron MY4ZIN-D2 24VDC (S) Miniature Power Relay
The Omron MY4ZIN-D2 24VDC (S) miniature power relay is a compact industrial relay engineered for automation systems that use 24VDC control voltage. Known for dependable switching and stable electrical performance, this relay is commonly integrated into PLC panels, machine controls, signal interfaces, and industrial process equipment.
As part of the Omron MY relay family, this model features four changeover contacts, LED indication, bifurcated contact construction, and built-in diode surge suppression. These characteristics make it highly suitable for modern industrial environments where control reliability and electrical protection are essential.
Technical Features of the Omron MY4ZIN-D2 24VDC (S) Miniature Power Relay
The relay operates with a 24VDC coil and contains a D2 diode suppression circuit. This integrated diode helps absorb reverse voltage generated when the coil is de-energized. In PLC-driven systems, this protection can reduce the risk of electrical noise affecting nearby electronic components.
The relay also uses bifurcated contacts to improve signal reliability. Instead of relying on a single contact point, bifurcated contacts divide the switching path into two separate contact surfaces. This construction supports more stable switching behavior in low-energy control circuits.
Its 4PDT configuration allows multiple independent circuits to be switched simultaneously from one relay operation. This makes the relay useful in complex control logic applications.
Common Industrial Uses
The Omron MY4ZIN-D2 24VDC (S) miniature power relay is widely used in industrial automation panels, packaging systems, conveyor controls, robotic equipment, and process control systems. Since many automation systems operate with 24VDC control voltage, this relay fits naturally into modern PLC architectures.
Engineers also use this relay for signal isolation, output expansion, alarm management, and machine interlock systems. The relay’s compact dimensions allow efficient panel layouts while maintaining multiple contact outputs.
Its plug-in socket mounting structure simplifies maintenance operations because the relay can be replaced without disconnecting wiring from the socket base.
