HIGH-DEFINITION LCD SCREEN: This timer relay module is equipped with a liquid crystal display, the current mode and parameters are clear at a glance, and the reading is clear. Supports UART data upload and parameter setting. SUPERIOR PERFORMANCE: This delay relay module has a wide power supply voltage of 6~30V, supports 5.0V micro USB power supply, supports high and low level triggers and switch control, supports continuously adjustable timing range: 0.01s-9999min, which is suitable for most applications. All parameter settings are automatically saved when the power is turned off. INDEPENDENT PARAMETER SETTING: The delayed shutdown cycle timer module supports UART data upload and parameter setting. Different parameters OP, CL, LOP can be set, these parameters are independent of each other and saved separately. AUTOMATION: This timer relay has a one-button emergency stop function (STOP button), with reverse connection protection. Increase the sleep mode, no operation within 5 minutes after power-on, automatically turn off the LCD backlight, any key to wake up the screen. ANTI-INTERFERENCE: This trigger cycle timer switch uses industrial-grade circuit boards, with optocoupler isolation, which improves the anti-interference ability and is safe and reliable. Different parameters 0P, CL, LOP can be set, these parameters are independent of each other and saved separately. Specification: Item Type: Delay Relay Module Working Voltage: 6-30V Time Range: 0.01s-9999min continuously adjustable Trigger Signal Source: High Level Trigger (3.0V~24V), Low Level Trigger (0.0V~0.2V), Switching Quantity Control (Passive Switch) Output Capacity: Can control devices within 30V, 5A range or 220V, 5A range Quiet Current: 15mA Operating Current: 50mA Lifespan: >100 000 times Working temperature: -40~85C Size: 88x3.8x1.9cm/3.15x1.5x0.75in Note: The data are all measured manually, please allow 1-3cm error due to differences in light and display, there may be some color differences, please refer to the actual item received.
