Welcome to our shop! This Delay Module is made of high-quality Printed Circuit Board material. It has a wide voltage range, making it compatible with most equipment. It is very convenient to use and features a one-button emergency stop function. It also has reverse connection protection, so you don't have to worry about burning it in case of reverse connection. The interface of this module is clear and simple, making it easy to understand and suitable for various work scenarios. It also has a sleep mode, which automatically turns off the display if there is no operation within 3 minutes, saving energy and being environmentally friendly. You can wake it up by pressing any key. This module allows you to set different parameters such as OP, CL, LOP, CLL, CLH. These parameters are independent of each other and can be saved separately. It also has a new serial port communication function, which makes it convenient to read and set parameters. All set parameters are automatically saved after power-off. The working voltage of this module is DC 5-30V and it can be triggered by a high-level trigger (DC3V-24V), switch trigger, or serial communication trigger. It can control equipment within DC30V 5A or AC220V 5A. The quiescent current is 20mA and the working current is 50mA. It has a service life of more than 100,000 times and can work in a temperature range of -40℃ to 85℃. This Delay Module is perfect for industrial control and electronic equipment applications. It is reliable, versatile, and durable. 100% Satisfaction: Our customers are our top priority.
