Features: 1. With delay ON, delay OFF, self-locking and trigger delay function. 2. With power supply anti-reverse function to prevent damaging the module. 3. There are three working voltage versions of 5V/12V/24V for users to choose from. 4. The delay time can be arbitrarily set between 0.1 seconds and 120 seconds. 5. The 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 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 interface: Module voltage / signal input has 3 wiring terminals. 1.
