Cara kerja modul ini adalah menunda nyala relay selama beberapa detik(dapat diatur lamanya) Spesifikasi: The delay time is adjustable (0~10 seconds) maksimal kisaran 6detik tambahkan resistor jika ingin lbih lama. The delay time can be increased by increasing the potentiometer. The delay time can be increased by increasing the capacitor C1. With input power indicator light With relay pull-in indication light It can control AC 220V/10A lower equipment. (Maximum control equipment 2000W) With relay freewheeling protection. Delay time formula: T=1.1RC. For example: capacitance 100uf resistance 100K T=1.1*100000*0.0001=11 seconds
