About Omron MY4N-D2 4PDT Relay
The MY4N-D2 is an Omron MY-series miniature power relay designed for multi-circuit switching in industrial control panels and automation equipment. It combines four changeover contacts, an LED operation indicator, and a built-in diode that suppresses the reverse voltage generated when its DC coil is de-energized.
Key Features
- Four-pole changeover contacts: Provides four independent SPDT contact sets in a compact 4PDT relay configuration.
- Built-in suppression diode: Absorbs coil-generated reverse voltage to help protect compatible DC control circuits and transistor outputs.
- LED operation indicator: Provides a clear visual indication when the relay coil is energized.
- 3 A contact capacity: Switches resistive loads up to 3 A at 220 VAC or 24 VDC under the specified conditions.
- Fast switching response: Provides operation and release times of 20 ms maximum, excluding contact bounce.
- Long operating endurance: Delivers at least 100 million mechanical operations and 200,000 electrical operations at rated load.
- Replaceable plug-in construction: Uses 14-pin terminals for convenient installation and maintenance with compatible Omron sockets.
Compatible sockets include PYF14S, PYF14T, PYF-14-PU, PYFZ-14, PYFZ-14-E, PY14 and PY14-02. Sockets are ordered separately. Because the relay contains a diode, verify the coil polarity and rated voltage printed on the actual relay before wiring.
