Time delay module with relay and LED display 12V

Product detailed description

This module is designed to control the switching using a set time interval.

Terminal block:

• NC: Relay switching contact = active when voltage is applied to the relay coil (relay closed)
• COM: Switching power supply input = here we connect the voltage we want to switch
• NO: Relay opening contact = active when the voltage to the relay coil is disconnected (relay open)
• DC+: Relay supply voltage = +12 V
• DC-: Relay supply voltage = GND
• X1: Input detection = switching signal

Specifications:

• Relay: Songle SRD-12VDC-SL-C (250AC 10A)
• Working voltage: 12V
• 8 preset functions can be selected using the buttons on the board (can be saved)
• The minimum set time is 1 second
• Dimensions: 66x40x1.5 mm

Function settings:

The module has a function to automatically turn off the display after about 10s if it is not in setup mode. After this time, the display and LED indication will go out. However, the module remains in operation and performs the set function. The LED indicating the relay on/off also remains in operation. If you want to call up the current status of the module, just press the SET button briefly and the display and LEDs will show the current status of the module for 10s.

Switching the module to setup mode: if the display is not lit, you must first press the SET button briefly and then press it long. If the display is lit, a long press is all it takes. The function setting will flash on the display. This switches the relay into configuration mode.

Pressing the SET button switches between setting individual values. The current position is indicated by the corresponding LED:

• MD = Function
• T1 = Time 1
• T2 = Time 2
• NX = Number of repetitions

Pressing the SW1 button switches the position of the active value to be edited. The current position is indicated by flashing the position on the display.
The value of the set position is changed using the +/- buttons.

To exit the setting mode and save the set values, long press the SET button. After the setting routine is completed, the module immediately starts to perform the set function.

Description of functions:

1. Disconnection after the set time: the relay is disconnected when power is applied; the delay time T1 is reached and the relay is disconnected (T1 is adjustable from 0 to 270 hours).
2. Disconnection after a set time (recurrent switching): the relay is disconnected when the delay time T1 is reached and switched on when the relay reaches the time delay T1 (T1 is adjustable from 0 to 270 hours).
3. Cycle mode 1: The relay does not switch on when switched on. When T1 runs out, the relay opens. When T2 is reached, the relay will trip. The cycle continues (T1 and T2 can be set from 0 seconds to 270 hours).
4. Cycle mode 2: The relay switches when switched on. When T1 runs out, the relay switches. When T2 runs out, the relay opens, and the cycle repeats.
5. Self-lighting relay mode: the relay closes when a high level pulse signal is applied to X1 and reopens on the next high level pulse signal.
6. Trigger relay mode: the relay closes when a high signal level is applied to X1 and opens when the high signal level ends.
7. Limited Cycle Mode 1: This mode allows you to increase cycles based on function 3. In this mode, T1 and T2 are adjustable from 0 seconds to 9999 seconds, and the cycle can be selected from 1 to 9999 times.
8. Limited Cycle Mode 2: This mode allows you to increase cycles based on function 4. In this mode, T1 and T2 are adjustable from 0 seconds to 9999 seconds, and the cycle can be selected from 1 to 9999 times.
