Coil Ratings (Common to Input/Output per Relay)
| Rated voltage (V) | Rated current (mA) | Coil resistance (Ω) | Must operate | Must release | Maximum voltage | Power consumption | |||
| 50 Hz | 60 Hz | of rated voltage | per Relay | per 16 Relays | |||||
| AC | 100/110 200/220 | 8.2 4.1 | 7/7.7 3.5/3.85 | 8,700 33,300 | 80% max. | 30% min. | 1.05 | 0.7 VA | 11 VA |
| DC | 12 24 100/110 | 42 21 5 | 290 1,150 20,000 | 80% max. | 10% min. | 1.05 | 0.5 W | 8 W | |
Note:
1. The rated current and coil resistance are measured at a coil temperature of +23°C with a tolerance of +15%/-20% for AC rated current and ±15% for coil resistance.
2. The operating characteristics are measured at a coil temperature of +23°C.
3. The value for maximum voltage is the maximum value within the allowable voltage fluctuation range for the relay coil's operating power supply. Continuous operation at this voltage is not within product specifications.
4. Approx. 4 mA flows into each LED indicator. To calculate the power supply capacity, add the current value of each LED indicator.
