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).

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 temperature 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 resistor if required.
