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.
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.
