Omron MY2N-CR 220/240VAC (S)

Omron MY2N-CR 220/240VAC (S) Miniature Power Relay

The Omron MY2N-CR 220/240VAC (S) miniature power relay is a 2-pole DPDT plug-in relay designed for control panels, industrial automation circuits, sequence control, and power switching applications. This model uses a 220/240 VAC coil and includes a built-in CR circuit for coil surge absorption, helping reduce electrical noise when the coil is switched off.

According to Omron Industrial Automation, this relay has plug-in terminals, an LED operation indicator, silver alloy contacts, and a closed protective cover. Its contact rated load is 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 DC loads. The coil resistance is listed as 18,790 ohms, and the operating voltage is 80% max. of the rated voltage. :contentReference[oaicite:0]{index=0}

Omron MY2N-CR 220/240VAC (S) Key Technical Characteristics

This relay is commonly selected where an AC control voltage is already available in the panel. The CR surge absorber is especially useful in systems where coil switching noise could affect nearby control devices, sensors, timers, or PLC input circuits. Because it is socket-mounted, replacement and maintenance are easier than with soldered relays.
