The Omron MY2ZN-D2 DC24 is a DPDT general-purpose relay from the MY Series, with a 24V DC coil. It mounts into a K-style 8-pin socket — the same footprint that panel builders and OEMs have used for decades in control cabinets. The contact rating is 5 A at 240V AC and 5 A at 24V DC, so it handles typical pilot-duty loads like contactor coils, solenoid valves, and indicator lamps without derating concerns at those levels. A built-in LED indicator gives immediate visual confirmation of coil energization — useful during panel commissioning or fault tracing. The lockable push-to-test button lets you manually actuate the relay for circuit checks without energizing the coil, which saves time when the control voltage isn't available.
Ratings that matter for the buyer
The 5 A contact rating at 240V AC is the headline number, but the motor-rated flag (Yes) means this relay is also specified for switching small inductive motor loads — backed by horsepower ratings of 1/10 hp at 120V AC and 1/6 hp at 240V AC. That covers fractional-horsepower pumps, fans, and conveyor drives in control panels. For DC switching, the 5 A at 24V DC rating is the same as the AC figure, so it works well on 24V DC control circuits common in PLC output interfaces. Dielectric strength is tested at 2,000V AC between coil and contacts, and 1,000V AC between contacts of the same polarity — both for one minute at 50/60 Hz. That gives confidence in isolation integrity for basic insulation in industrial environments. Electrical durability is rated at 200,000 operations; mechanical durability at 50,000,000 operations — so the mechanical life far exceeds the electrical life under load, which is typical for this relay class.
