Описание и характеристики

Description:Wide voltage 5V-30VTime can be adjusted via a potentiometer, meeting your most occasionsMicro USB 5.0V power supply with input, easy to use5--30V wide supply voltageExternal triggering and onboard buttons Two triggering methodsWith a relay pull-in indicatorInterference ability, under various interference will not malfunction relay for industrial control.Module features:1. Working voltage: Wide voltage any voltage between 5-30V, Micro USB power connector and two solder terminals2. Operating mode: feed the module power, output of the module state: normally open (NO) and the common terminal (COM) disconnected, normally closed (NC) and the common terminal (COM) is turned on.Originating outside the contact (TRIG) to a low pulse signal, or touch trigger button and instantly, the relay and, working lights, this time, the status of the relay output: normally open (NO) and the common terminal (COM) is turned on, Normally Closed (NC) and the common terminal (COM) is disconnected after 0-24 seconds (this time can be adjusted according to your needs) relay opens after the bell, then relay back to the state before the trigger.3. The time can be adjusted via a potentiometer, default 0-24 seconds. If you need more time, more replaceable capacitor (C2) or potentiometer. Delay time formula: T = 1.1RC. For example: 1M resistor capacitor 22uf then T = 1.1 * 0.000022 * 1000000 = 24.2 seconds.4. With a relay indicator.5. The module can be controlled: 10A 250VAC (AC), 10A 30VDC (direct
