Reset Coil
| Rated Voltage (V) (Usable Voltage Range) | Open Contact Voltage (Coil Temperature 20 ±2°C) | Rated Value Excitation Current (Coil Temperature 20 ±2°C) | Coil Resistance (Coil Temperature 20 ±2°C) | Permitted Application Time |
|---|---|---|---|---|
| 24 V DC ±10% (21.6 to 26.4 V DC) | 21.6 V or less | 185 mA ±20% | 130Ω ±20% | 100 ms or more 1s or less |
Note 1. Please do not flow current to the coil for over 10 seconds. This may cause loss of performance.
Note 2. If the reset coil is controlled using a semiconductor element, etc., make sure that any residual voltage generated due to leakage current is 2.4 V DC or less.
