SMAKN® Wide Voltage 5V-30V Power Supply Adjustable Trigger Delay Time Relay Module;

*Operating voltage: 5V-30V (wide voltage)
*Both MicroUSB and welding power supply interface terminals
*Operating modes: power to the module, the module status of the output: normally open (NO) and the common terminal (COM) is disconnected, normally closed (NC) and the common terminal (COM) is turned on.
*With a relay indicator.
*Has continued flow protection relay.
*Module is designed with a pull signal terminal and filter circuit, anti-jamming capability, suitable for industrial control. Many manufacturers have added optocoupler isolation, but with the trigger signal to the module is not isolated, would not achieve the interference effect. After the test was found to enhance the stability of the trigger end to interference, regardless of this module is under electromagnetic interference environment, or instantly through power module, the relay will not malfunction.
*Modules can be controlled: 10A 250VAC (AC), 10A 30VDC (DC) below the load.
*Dimensions: 54 * 19 * 18mm (L * W * H)
*Weight: 16g
Applications:
*Anti-theft alarm delay, building sound and light control light switch.
*Delay-vehicle device is turned on, to prevent excessive current when the car ignition burn-vehicle device.
*Need to have in order to start the occasion, to prevent multiple devices at the same time to start burning electrical current is too large.
