Omron MY2N 48VDC (S) Miniature Power Relay
The Omron MY2N 48VDC (S) miniature power relay is a socket-mounted control relay built for 48 VDC systems. It combines a compact relay body, DPDT switching, plug-in terminals, and LED operation indication. This makes it a practical choice for control panels where reliable switching and quick maintenance visibility are required.
In industrial automation, 48 VDC control circuits are often found in telecommunications equipment, transport systems, energy-related panels, battery-backed systems, and specialized machinery. The MY2N 48VDC version fits these environments by offering a dedicated 48 VDC coil rather than requiring external voltage conversion.
Technical Specifications
The Omron MY2N 48VDC (S) miniature power relay uses a 48 VDC coil with a rated current of approximately 17.6 mA. The coil resistance is listed as 2,725 ohms, and the operate voltage is 80% maximum of the rated voltage. These values help engineers verify whether the control power supply can energize the relay properly under real operating conditions.
The relay uses a DPDT contact form, also described as two changeover contacts. Contact material is silver, and the relay is built with plug-in terminals for socket installation. Its contact 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.
Why the 48VDC Coil Matters
Using the correct coil voltage is essential. A 24 VDC relay should not be used in a 48 VDC circuit, and a 110 VDC relay may not operate correctly at 48 VDC. The MY2N 48VDC (S) gives designers a dedicated option for DC systems that operate above common 24 VDC levels.
The LED indicator is also valuable in 48 VDC panels. When a system contains multiple relays, a visible operation indicator can help technicians identify energized circuits without measuring every coil terminal. This improves service efficiency and supports safer troubleshooting routines.
Applications
This relay can be used in auxiliary switching, alarm circuits, control signal routing, interposing relay panels, and low-power field device control. Its two-pole design allows one relay to perform multiple switching tasks. For example, one contact can control a device while the other provides feedback to a controller or monitoring system.
The relay’s socket-based design also supports modular maintenance. If a relay reaches the end of its service life, it can be replaced without disturbing the surrounding wiring, provided the socket and wiring remain in good condition.
Installation Notes
Before installation, confirm the coil polarity requirements, circuit voltage, load type, and compatible socket. For inductive DC loads, additional suppression may be useful to reduce contact wear and electrical noise. The relay should be installed in a clean control enclosure with suitable ventilation and protection from excessive vibration.

Omron MY2N 48VDC (S) FAQ
What is the coil voltage of the Omron MY2N 48VDC (S)?
The relay uses a 48 VDC coil with a rated current of approximately 17.6 mA.
What does the LED indicator show?
The LED indicator shows when the relay coil is energized, helping maintenance teams verify relay operation quickly.
Is the relay suitable for 24 VDC systems?
No. This model is designed for 48 VDC coil operation. A 24 VDC system should use a relay with a matching 24 VDC coil.
What type of contacts does it have?
It has DPDT contacts, meaning two changeover circuits are controlled by one relay coil.
Can it switch inductive loads?
Yes, but inductive loads must remain within the specified rating, and suppression should be considered to protect contacts and reduce electrical noise.
