There are three types of Omron's MY series relays: 2-pole and 4-pole changeover contact arrangements, and AC and DC coil voltages.
All models are equipped with mechanical indicators and nameplates, on which identification data can be added. The mainstream and fully functional models have an LED indicator. For the DC coil voltage type, the indicator lights green, and for the AC coil voltage type, the indicator lights red. In addition, the fully functional relay also has a color-coded two-way action test button for manual testing. The plug-in relay series provides screw terminals or screwless clamp (SLC) terminal sockets for your choice to achieve maximum installation flexibility. The company says that highly reliable relays comply with all relevant international standards, including UL, CSA, VDE, LR and CE.
