Specification: Working voltage: DC 5V, 12V, 24V (Optional) Working current: <80mA at 5V (<1mA when the relay is not operating) <35mA at 12V <1mA when the relay is not operating) <18mA at 24V (<1mA when the relay is not operating) Load capacity: -normally open port: DC 0-30V/10A, AC 0-250V/10A -normally closed port: DC 0-28V/10A, AC 0-125V/10A Working temperature: -20~60℃ (limit range -30~70℃) Size: 60*35*20mm / 2.36*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. The delay time T1 can be adjusted between 0.1 second and 120 seconds. Power-on delay pull-in: After the delay of T1 from the start of power-on, the relay pulls in and sends a high-level pulse to the X1 interface at any time. This function resets and restarts. The power-on delay is disconnected: the relay is closed when the power is turned on. After the T1 time is closed, the relay is disconnected, and a high-level pulse is given to the X1 interface at any time. This function is reset and restarts. Module interface: Module voltage / input has 3 wiring terminals. 1. DC+: DC power supply positive 2. DC-: DC power supply negative 3. X1: input detection interface Relay load output has 3 wiring terminals. 1. COM: relay common interface 2. NO: relay normally open interface 3. NC: relay normally closed interface Package list: 1 * Delay Timer Relay
