General-purpose Relay  
LY  
A Miniature Power Relay  
• Equipped with arc barrier.  
• Dielectric strength: 2,000 V.  
• Built-in diode models added to the LY Series.  
• Single-pole and double-pole models are applicable to operating  
coils with ratings of 100/110 VAC, 110/120 VAC, 200/220 VAC,  
220/240 VAC, or 100/110 VDC).  
• Three-pole and four-pole models are applicable to operating  
coils with ratings of 100/110 VAC, 200/220 VAC, or 100/110  
VDC).

Note: 1. When ordering, add the rated coil voltage to the model number. Rated coil voltages are given in the coil ratings table.  
Example: LY2, 6 VAC  
Rated coil voltage  
2. Relays with #187 quick connect terminals are also available with SPDT and DPDT contact. Ask your OMRON representative for details.  
3. SEV models are standard Relays excluding DPDT (bifurcated) models.  
4. VDE- or LR- qualifying Relays must be specified when ordering.

Note: 1. The rated current and coil resistance are measured at a coil temperature of 23°C with tolerances of +15%/–20% for rated currents and  
15% for DC coil resistance.  
2. Performance characteristic data are measured at a coil temperatures of 23°C.  
3. AC coil resistance and impedance are provided as reference values (at 60 Hz).  
4. Power consumption drop was measured for the above data. When driving transistors, check leakage current and connect a bleeder re-  
sistor if required.

Precautions  
Refer to page 11 for general precautions.  
■ Connections  
Do not reverse polarity when connecting DC-operated Relays with  
built-in diodes or indicators.  
ALL DIMENSIONS SHOWN ARE IN MILLIMETERS.  
To convert millimeters into inches, multiply by 0.03937. To convert grams into ounces, multiply by 0.03527.
