This is a cycle delay timer module with an LED display. The module adopts MCU as the main chip, so it has high timer precision and reliable performance. Its working voltage is DC 12V and its working current is 50mA. You can use it to control the reciprocating stroke, or repetitive power on and off for equipment and products burn-in tests. Moreover, it can be widely used in timer operating equipment, repetitive testing circuit, and fish tank intermittent pumps. Specifications of 2 Button 12V Dc Programmable Adjustable Timer Relay Module: Product Name: 2 Button 12v Dc Adjustable Timer Relay Module Working voltage: DC 12V Source: DC4V ~ 20V (positive trigger common power button, PNP sensors, PLC signals, etc.) Output capability: You can control the DC 5V~30V 10A & AC 220V 10A Quiescent Current: 20mA, working current: 50mA Life: more than 10 million times; Working temperature: -40 ~ 85’C; Dimensions: 64.2mm * 34.8mm * 18.5mm Features of 12v Dc Digital LED Display Programmable Timer Switch Trigger Cycle Module: anti-reverse voltage input circuit, worry-free wiring. Signal input optocoupler isolation, anti-interference ability. Set the parameters of power and permanent memory. Powerful flash MCU online programming capabilities, according to user needs can contact the manufacturers to customize the functionality. Receives a trigger signal to start the countdown, while the relay, timing the end of the relay to stop working, time to recover to the set, waiting for the next trigger. Instructions of 12v Digital LED Timer Module Adjustable Timer Relay Time Control Switch Trigger Timing Board: Click K1 enter the time setting, one hundred digital starts flashing, then press K2, one hundred the number of changes; then click K1 ten digital start flashing, then press K2, the tens digit changes; then click K1 bit digital start flashing, then press K2, single-digit change; then click K1, exit the setting, LED no longer flashes. Normal digital tube display, press K2, shifting the decimal point, a decimal point indicates 0-999 minutes in 10 bit from 0 to 99.9 seconds with no decimal point represent 0-999 seconds; to this time setting is completed.

LM2596 DC-DC Buck Converter Step Down Module Power Supply is a step-down(buck) switching regulator. LM2596 Buck is capable of driving a 3-A load with excellent line and load regulation. These devices are available in fixed output voltages of 3.3 V, 5 V, 12 V, and an adjustable output version. The LM2596 Stepdown module is operating at a switching frequency of 150kHz, thus allowing smaller sized filter components than what would be required with lower frequency switching regulators
