The Omron MY4ZN-D2 DC24 (S) is a 4PDT general-purpose relay from the MY Series, designed for socket mounting with a G-style socket (14-pin). Coil is 24V DC, and the contacts are rated 3 A at 250V AC and 3 A at 30V DC — enough for moderate switching of control signals, small motors, and pilot loads. A lockable push-to-test button and LED indicator are built in, which speeds panel troubleshooting.
Contact ratings and durability
The 4PDT arrangement gives you four independent switching channels in one package — useful for interlocking multiple circuits from a single coil. AC rating is 3 A at 250V; DC rating is 3 A at 30V. Electrical durability is 100,000 operations; mechanical durability is 50,000,000 operations, so the relay handles high-cycle applications like conveyor interlocks or machine sequencing without early wear.
Integration notes
Socket mounting (G socket, 14 pins) means the relay plugs into a pre-wired base — no soldering, quick swap for MRO. The lockable push test button lets you manually actuate the relay during commissioning or fault isolation without energizing the coil. Dielectric strength between coil and contacts is 1,000V AC for 1 minute, which meets typical panel isolation requirements.
