TRM01 delay relay module adopts high quality components and features stable performance and simple operation. It could be widely used in various control situations requiring delayed self-locking.The module is preset with 4 functions to meet a variety of applications, and can customize and add other specific functions according to user needs. Features: With anti-reverse power function to prevent damage the module.There are three working voltage versions of 5V/12V/24V for users to choose from.The delay can be arbitrarily set between 0.1 seconds and 120 seconds.With delay enabled , delay off, self-locking and trigger delay function. Parameters can be saved and the setting contents are not lost when power off.Specification:Working voltage: DC 5V, 12V, 24V (optional)Working current:; 80mA at 5V (; 1mA when relay does not work); 35mA at 12V; 1 mA when the relay does not work); 18mA at 24V (; 1mA when relay is not working) Load capacity: 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 (limit range -30~70)Size: 60 * 35 * 20mm / 2.35 * 1.38 * 0.79in Package weight: approx. 23g Module function: The user can select one of the following four functions by pressing the button. The delay time can be selected by adjusting the potentiometer.T1 delay can be set between 0.1 seconds and 120 seconds.F1 function: Power-on delay: After the delay of T1 from the start of power-on, the relay inputs and sends a high level pulse signal to the X1 interface at any time.
