Note:Note:

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.

Note:2. Performance characteristic data are measured at a coil temperature of 23°C.

Note:3. AC coil resistance and impedance are provided as reference values (at 60 Hz).

Note:4. Power consumption drop was measured for the above data. When driving transistors, check leakage current and connect a bleeder resistor if required.

Note:5. Rated voltage denoted by "*" will be manufactured upon request. Ask your OMRON representative.
