When ordering, add the rated coil voltage to the model number. Example: G5NB-1A DC5 Rated coil voltage However, the notation of the coil voltage on the product case as well as on the packing will be marked as VDC. Note 2. When ordering tape packing, add-S to the model number. Be sure since-S is not part of the relay model number, it is not marked on the relay case. 1G5NB PCB Power Relay Ratings Coil Item Must operate voltage Must release voltage Max. voltage Rated current Coil resistance Power consumption (V) (V) (V) (mA) () (mW) Rated voltage % of rated voltage 5 VDC 40 125 Standard: 12 VDC 16.7 720 10% min. 180% (at 23C) Approx. 200 75% max. 18 VDC 11.1 1,620 10 to 31%* High-capacity: Approx. 32* 170% (at 23C) 24 VDC 8.3 2,880 Note 1.
