DC 12V 1 Channel Relay Module FRM01 Multifunction Relay Loop Delay Timer Switch SelfLocking Timing [XR]

1. Newly upgraded to version 2.0, with the module functions increased from 8 to 18 to meet more application requirements;2. The anti-reverse connection function of power supply is added, so that the module not be damaged due to wrong power supply connection;3. The system is more stable and reliable by using a high withstand voltage power supply module to replace the previous discrete power supply;4. The timing function of 0.1 second is added, and the timing accuracy is upgraded from the previous 0.1 second to 0.01 second;5. Add automatic power saving function, which users can set independently.Module interface:Module control end: there are 3-wire interfaces, and all interfaces have terminals, which are convenient for users to use.1. DC+: positive pole of DC power supply (5V, 12V and 24V modules are available).2. DC-: negative pole of DC power supply3. CH1: Input detection interface, active at high level.Relay output: there are 3-wire interfaces, and all interfaces have terminals.1. NO: normally open interface of relay, which is suspended before being pulled in and shorted with COM1 after being pulled in.2. COM: public interface of relay3. NC: normally closed interface of relay, which is short-circuited with COM1 before being pulled in and suspended after being pulled in.FRM01 multi-function relay control module is specially designed for users with different needs. It uses a microcontroller as the main control unit, preset 18 functions, and the module adopts high-quality power relay, high-power high-voltage triode, red and blue signal indicators, and the board layout is comprehensive and stable, which can be widely used in power control occasions.Colour:As ShownMaterial:PCBPackage Contents:1 * FRM01 12V multi-function relay control moduleOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
