The relay module at; delay TRM01 adopts high quality components. and features stable performance and simple operation. in various control situations requiring delayed self-locking.The module is pre-tuned; with 4 functions to meet your needs. a variety applications, and can customize and add other specific functions according to user needs.Features:With anti-reverse power function to prevent damage to the module.There are three versions of working voltage of 5V/12V/24V for users to choose.The delay time can be arbitrarily set between 0.1 seconds and 120 seconds.With delay on, delay off, self-locking and trigger delay function. are not lost when power off.Specification:Working voltage: DC 5V, 12V, 24V (optional)Working current:; 80mA at; 5V (; 1mA when relay not working); 35 mA at; 12V; 1 mA when the relay is not working); 18mA at; 24V (; 1mA when the relay is not working) Charging: Normally Open Port: DC 0-30V/10A, AC 0-250V/10A Normally Closed Port: DC 0-28V/10A, AC 0-125V/10A Operating Temperature: -20~60 (range limit -30~70)Size: 60*35*20mm/2.36*1.38*0.79inPackage weight: approx.23gModule function:User can select one of the following four functions by pressing button. Delay time can be selected; by adjusting the potentiometer. The delay T1 can be set. between 0.1 second and 120 seconds.Function F1:Delay power-up: after the delay from T1 to From the start of energizing, the relay enters and sends a high-level pulse signal to the relay. the X1 interface to; any time.
