Omron MY2N 48/50VAC (S) Miniature Power Relay
The Omron MY2N 48/50VAC (S) miniature power relay is a plug-in electromechanical relay designed for AC control circuits. It is part of Omron’s MY relay family, known for compact construction, reliable switching, and broad compatibility with socket-based panel installations.
This model is commonly selected when a control system uses a 48 VAC or 50 VAC coil supply. It provides a DPDT contact arrangement, LED operation indication, plug-in terminals, and silver contacts. These features make it useful in machine control, building automation, equipment panels, and industrial sequence circuits.
Technical Overview
The Omron MY2N 48/50VAC (S) miniature power relay is a two-pole relay with single contacts and plug-in terminals. Its DPDT contact form allows two separate circuits to be switched from one coil signal. This can be useful when one control action must operate two loads, separate feedback signals, or split control paths.
Like other MY2N models, this relay is designed for socket mounting. Socket installation makes panel wiring cleaner and allows quick relay replacement during maintenance. The closed cover protects the relay mechanism, while the built-in LED indicator gives immediate visual confirmation of coil operation.
Contact Ratings and Switching Capability
The MY2N series is rated for practical control-panel loads. Typical ratings include 220 VAC 5 A for resistive loads, 220 VAC 2 A for inductive loads, 24 VDC 5 A for resistive loads, and 24 VDC 2 A for inductive loads. These ratings support a wide range of control tasks, including pilot lamps, small solenoids, auxiliary circuits, control signals, and interface applications.
When switching inductive devices, designers should consider arc suppression, load type, duty cycle, and expected electrical life. Contact ratings should not be treated as universal limits for every load profile. A motor, solenoid, or contactor coil may create higher stress than a purely resistive device with the same current value.
Practical Applications
The 48/50VAC coil version is often used in legacy machinery, regional control systems, and equipment where AC auxiliary voltage is already available. It can serve as an interface relay between control switches and field devices, or as a compact switching element inside equipment panels.
Because it has two changeover contacts, the relay can provide control flexibility. One contact may be used for a load circuit while the other provides status feedback. Alternatively, both contacts may be used to control separate circuits that must change state together.
Selection Considerations
Before using the Omron MY2N 48/50VAC (S) miniature power relay, confirm the coil voltage, frequency, socket type, and load characteristics. The relay should be installed in a compatible socket, with wiring sized according to the current and applicable panel standards.
