Features: Time can be adjusted through the potentiometer, meet your most occasions of use. With a MicroUSB 5.0V power supply input, use very convenient. 5~30v ultra wide power supply voltage. External trigger and onboard button two trigger modes. With the relay and light. Strong anti-jamming capability, all kinds of interference relay misoperation, won for industrial control. Specification: 1. Working voltage: arbitrary between 5~30V voltage, wide voltage Micro USB and welding terminal two power supply interface 2. The working mode: to the module power supply, and the output module status to: normally open (NO) with the public (COM) disconnect, normally closed (NC) with the public (COM) conduction. 3. Originated in the outside contact (TRIG) to a low pulse signal, or instant touch trigger buttons, relay and absorption, the work light is lit, at this point, the relay outputs status to: normally open (NO) with the public (COM) conduction, normally closed (NC) with the public (COM) disconnect, after 0 to 24 seconds (this time can be adjusted according to your demand) relay disconnect after bell, the relay back to the state before the trigger again. 4. A relay and indicator lights. 5. The module can control: 10A 250VAC (AC), 10A 30VDC (DC) under load. 6. With continued flow protection relay. 7. The module design have a pull-up and filter circuit, signal end anti-interference ability is strong, suitable for industrial control.Many manufacturers have added light coupling in isolation, but module with the trigger signal is not isolated, not the anti-interference function.Through a test and found or improve the anti-jamming, triggering the stability to the module under electromagnetic interference environment, or through the moment of power module, relay will not produce false action. 8. Size: 5.4 * 1.9 * 1.9cm (length * width * height) 9. Weight: 16g
