Omron Panel Power Relay 110V AC / 120V AC Coil, 3A Switching Current, 4PDT Plug-In, Panel Mount MY4H 110/120VAC

Omron MY4H 110/120VAC Panel Power Relay is a compact, plug-in relay specifically designed to meet industrial automation and control environments that require reliable circuit switching. It operates with AC coil voltage at both 110V and 120V, making it suitable for a wide range of control panels and modular relay racks.

This relay features a 4PDT contact configuration, meaning it provides four independent changeover poles, enabling complex logic and control functions in automation systems. The plug-in terminal type is ideal for panel mounting, allowing quick insertion and replacement in relay sockets.

Gold-plated contacts help minimize signal loss and maintain switching consistency, with a contact resistance as low as 50mΩ to reduce voltage drop across switched circuits. The relay can handle a switching current of up to 3A at 110V AC, which supports moderate AC loads such as actuators, sensors, or signal routing devices.

With an envelope width, length, and height of 22.1mm, 28.44mm, and 35.1mm, respectively, the relay fits tightly packed relay arrays while allowing standard socket clearances. The relay is designed to operate reliably in ambient temperatures from -25°C to 60°C, suitable for most factory and equipment-room conditions.

Additional features include coil resistance of 4.4kΩ for efficient electrical actuation and panel mount design for straightforward installation. Applications include relay logic in industrial automation cabinets, signal routing in telemetry and monitoring systems, and low-voltage DC load switching up to 24V.

Operates with both 110V and 120V AC coil voltage for flexible use. Features four changeover poles (4PDT) for multiple circuit transitions. Gold-plated plug-in contacts minimize signal degradation and improve switching consistency.

Capable of switching 3A at 110V AC for moderate AC loads. Low contact resistance of 50mΩ reduces voltage drop. Panel mount design allows easy installation in industrial automation cabinets. Suitable for control panel switching, relay logic, telemetry and sensor actuation.

Functions reliably between -25°C and 60°C ambient temperatures.

Omron MY4 series relays are widely used in industrial, laboratory, manufacturing, and commercial automation scenarios where robust switching and reliability are critical. Explore more Omron relays and panel control products in the Electronics & Electricals category on EnvMart.
