Omron MY4N1 100/110VDC (S) Miniature Power Relay Technical Guide
The Omron MY4N1 100/110VDC (S) miniature power relay is a high-voltage DC coil relay designed for industrial control systems that operate with 100 or 110 VDC control power. This type of relay is often found in specialized automation panels, power-related control circuits, industrial machinery, and legacy systems where higher DC control voltage is already established.
The relay is listed with coil ratings of 100 VDC at approximately 8.7 mA and 110 VDC at approximately 9.6 mA. Coil resistance is about 11440 ohms, and power consumption is around 0.9 W. It includes an LED operation indicator, plug-in terminal structure, closed cover, and 4PDT contact form.
Contact Ratings and Electrical Capability
The Omron MY4N1 100/110VDC (S) miniature power relay supports 220 VAC at 3 A for resistive loads, 220 VAC at 0.8 A for inductive loads, 24 VDC at 3 A for resistive loads, and 24 VDC at 1.5 A for inductive loads. Maximum contact voltage is 250 VAC or 125 VDC. Maximum switching power is listed as 660 VA for resistive AC loads and 72 W for resistive DC loads.
Performance Values
The relay offers an operating time of 20 ms maximum and a reset time of 20 ms maximum. Insulation resistance is specified at 100 megaohms minimum at 500 VDC between key insulated sections. Dielectric strength includes 2000 VAC between coil and contacts for one minute under specified test conditions. Mechanical endurance reaches 100 million operations minimum, while electrical endurance reaches 200,000 operations minimum at rated load.
Omron MY4N1 100/110VDC (S) Typical Applications
This relay is appropriate for systems where 100/110 VDC control voltage is standard. It can be used for auxiliary switching, control logic, signal isolation, alarm circuits, interlock circuits, and multi-contact relay operations. The 4PDT design is especially useful when one DC command must switch several circuits at once.
Engineering Considerations
Because this model uses a higher DC coil voltage, technicians should verify polarity practices, insulation requirements, control supply stability, and panel safety procedures before installation. Correct socket selection is also important. The relay should not be selected only by coil voltage; the load current, load category, switching frequency, environment, and expected service life must also be reviewed.
