12V LED Display Timer Relay Module Delay Programmable Switch Board Car Buzzer CZ

Overview: 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 Specification:Product Name: Programmable timer relay moduleWorking voltage: DC12V (normal operating voltage DC10V-16V)Source: DC4V ~ 20V (positive trigger common power button, PNP sensors, PLC signals, etc.)Output capability: You can control the DC or AC 220v5A within 30v5A withinQuiescent Current: 20mA,working current: 50mALife: more than 10 million times;Working temperature: -40 ~ 85'C;Weight: about 26gDimensions: 64.2mm * 34.8mm * 18.5mmFeatures:S1: power on, press S1 2 seconds to enter mode selection menu, press S1, choose P-1 ~ P-4 mode.S2: OK / Shift key: Press to adjust the position of the LED is blinking, which LED is blinking, S3 to adjust the value of digital tube flicker. Until you press S2, the digital is no longer flashing.S3: digital display flashes, S3 adjustment digits from 0-9 successively changed. Normal digital tube display, S3 to adjust the position of the decimal point, the decimal point in bits 0-999 minutes; in 10 bit from 0 to 99.9 seconds; no decimal point indicates 0-999 seconds.Model Description:P-1: triggering signal is received, the relay is turned on, the timer expires, the relay off.A1: During the delay trigger again invalidA2: During re-timing delay trigger againA3: Delay trigger again during termination timing relay resetP-2: triggering signal is received, X start time, the end of counting relay, Y start time, the end of counting the relay offP-3: Cycle Switch ModeA1: After power relay is turned on, the end of the timing off, an infinite loop.A2: After power relay is off, the timing turned end, an infinite loop.Package Included:1 x 12V LED Display Timer Relay Module
