Platform Software Description

Juying Cloud Platform is a network platform software developed by our company, which includes mobile APP platform software and web version platform. The mobile APP software includes two categories: Android and IOS. The platform is designed for our company's DAM series network version devices and GPRS version devices, aiming to provide users with remote control output (relay, switch quantity), analog quantity (4-20mA, 0-10V, 0-5V) acquisition, switch quantity acquisition and other services, greatly facilitating user needs. The server is provided by our company, and customers can use it with confidence.

Working mode description

Introduction to the Flashing and Breaking Function

Manual mode: For each operation of the relay, the relay will flip once (open when closed, close when open);

Flashing mode: For each operation of the relay, the relay will close for 1 second (actual time =set number * 0.1) and then automatically disconnect;

Flashing mode: For each operation of the relay, the relay will disconnect for 1 second (adjustable time) and then automatically close;
