4X 12V 1 Channel Relay Module FRM01 Multifunction Relay Loop Delay Timer Self-Locking Timing Board

4X 12V 1 Channel Relay Module FRM01 Multifunction Relay Loop Delay Timer Self-Locking Timing Board Popis

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 will 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. +: positive pole of power supply (5V, 12V and 24V modules are available).
2. -: negative pole of 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 signal indicators, and the board layout is comprehensive and stable, which can be widely used in various power control occasions.
