DC 8V-36V 4 Channel LED Display Multifunction Relay Module Self-Locking Timing Relay Module

1. Linkage function of each channel; With 4 channels of input and output control, each channel can be set with 20 functions to meet more application requirements; DC 8V-36V wide voltage input, with power supply anti-reverse connection function, will not damage the module due to wrong power supply;
2. With power indicator light, relay pull-in indicator; At least 1 second timing function can be set, and the timing accuracy is better than 1%; Increase the automatic power saving function;
3. All setting options can be saved automatically, and the setting contents will not be lost when power is off; The trigger signal input terminal supports user selection, high level or low level pulse triggering;
4. Module function: The user can select one of the following 20 functions by pressing the button and display, and can arbitrarily combine the linkage mode between the various paths, and can set and save the function parameters. The T1 and T2 time parameters can be set. The time parameter is 1 Adjustable from seconds to 255 hours, the maximum accuracy is better than 0.01 seconds.

When selecting a high level trigger:
Function 1: Power-on delay pull-in: After delaying T1 time from power-on, the relay pulls in and sends a high-level pulse signal to the X interface at any time. This function resets and restarts operation;
Function 2: Power-on delay off: When the power is turned on, the relay is closed. After the T1 time is closed, the relay is disconnected. A high-level pulse signal is sent to the X1 interface at any time. This function is reset and restarts.
Function 3: Timing pull-in and then disconnect: the relay is disconnected at power-on, the relay is closed after the disconnection time T1 arrives; the relay is disconnected after the pull-in time T2 arrives, and a high-level pulse signal is given to the X interface at any time. Function reset and restart operation;
Function 4: Timing disconnection and re-sucking: the relay is closed when power is on, the relay is disconnected after the pull-in time T1 arrives; the relay is closed after the disconnection time T2 arrives, and a high-level pulse signal is given to the X interface at any time. Function reset and restart operation;
