Omron MY4 Series Power Relay, 110/120V AC Coil Voltage, 4PDT Contact Configuration - MY4H 110/120VAC


This power relay is a Compact plug-in switching device designed for control and automation environments where multiple circuit changes are required. It operates from an AC Coil and provides several isolated switching poles with low contact resistance, making it suitable for use in control panels and modular relay racks.

Features and Benefits:


• 110/120V AC Coil delivers straightforward mains-driven actuation
• Four changeover poles provide multiple circuit transitions
• Gold-plated contacts reduce signal degradation and improve switching consistency
• Contact resistance of 50mΩ minimises voltage drop in switched circuits
• Switching capacity 3A at 110V AC supports moderate AC loads
• Coil resistance 4430Ω limits current draw through the Coil

Applications


• Suitable for relay logic in industrial automation cabinets
• Ideal for control panel switching of sensors and actuators
• Used for signal routing in telemetry and monitoring systems
• Can be used for low-voltage DC load switching up to 24V

What Terminal arrangement does it use for panel installation?


It employs a plug-in Terminal format designed for panel mounting, enabling straightforward insertion and replacement in relay sockets.

What environmental temperatures can it operate within?


The device is specified to function between -25°C and 60°C, covering typical factory and equipment-room conditions.

What switching power limits should be observed for mixed loads?


The relay’s switching power is rated at 330VA, which should be used to determine combined voltage and current limits for AC load combinations.

How Compact is the relay for densely packed panels?


Its envelope width, length and height are specified to fit tight relay arrays while allowing standard socket clearances.
