Certification US: Certified by UL and CSA Ordering Information ■ List of Models Name Rated input voltage Model Voltage Detection Unit 12/24 VDC G32A-C-US Note: When ordering, specify the rated input voltage. 1 G32A-C Application Examples • The G32A-C can be used to prevent malfunction due to residual In rated operation, the G3PA turns ON at 4 V max. Ordinarily, the voltage, leakage current, and input noise. G3PA might turn ON if the residual voltage in transistor circuits exceeds 3 V. (The G32A-C makes voltage output at voltages exceeding 9.6 V.) Residual Voltage  The G32A-C can be used to improve the synchronization of input signals during 3-phase load switching.  The G32A-C can be used to fix the trigger voltage when using a timing circuit.
