Dsdhuf 1 Channel Relay Module Loop Delay Timer Switch Preset 18 Functions High Withstand Voltage for DC 12V

• 3. The system is more stable and reliable by using a high withstand voltage power supply module to replace the previous discrete power supply;
• 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;
• 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.

Dsdhuf 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 supply 3. 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 relay 3. 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 various power control occasions.
