DROK 200399 Timer Relay: Features, Specifications, and Operation Guide

Module Description

This section details the DROK Timer Relay module, which features a clear LCD display showing the current working mode and parameters. It is equipped with input terminals for power supply (6.0V-30V or Micro USB 5.0V) and trigger signals (High level trigger, Signal GND, Low level trigger). The module includes relay output terminals (NC, COM, NO) for controlling loads, and user interface buttons: STOP, SET, UP, and DOWN. A relay closing indicator LED is also present.

Sleep mode: After 5 minutes of inactivity, the backlight automatically turns off to save power. Any key press will wake the device.
STOP key provides one-button stop functionality.
All set parameters are automatically saved when the device is powered off.

Parameter Instruction

OP: Operate time (duration the relay remains ON).
CL: Close time (duration the relay remains OFF).
LOP: Loop times (settable from 1 to 9999 times; "---" indicates infinite loop).

Working Modes (P1-P7)

The relay supports seven distinct working modes:

P1: Relay turns ON for time OP after receiving a trigger signal, then turns OFF. The input signal is ignored during the OP delay.
P2: Relay turns ON for time OP after a trigger signal, then turns OFF. The module restarts timing if a trigger signal is received again during the OP delay.
P3: Relay turns ON for time OP after a trigger signal, then turns OFF. The module resets and stops timing if a trigger signal is received again during the OP delay.
P4: Relay turns OFF for time CL after a trigger signal, then turns ON for time OP. The relay turns OFF after completing the timing sequence.
P5: Relay turns ON for time OP after a trigger signal, then OFF for time CL, repeating this cycle. The loop stops if a trigger signal is received during the cycle.
P6: Relay turns ON for time OP after power-on (without a trigger signal), then OFF for time CL, repeating this cycle. The number of cycles (LOP) can be configured.
P7: Signal hold function. If a trigger signal is received, the timing resets, and the relay remains ON. When the signal is removed, after time OP, the relay turns OFF. Receiving another signal during the timing process resets the timer.

How to Select Timing Range

The timing range is continuously adjustable from 0.01 seconds to 9999 minutes. To select the timing range, short press the STOP key while in the OP/CL parameter setting interface. The position of the decimal point on the LCD indicates the selected range:

XXXX (No decimal point): Timing range: 1 sec - 9999 sec
XXX.X (Decimal after tens): Timing range: 0.01 sec - 999.9 sec
XX.XX (Decimal after hundreds): Timing range: 0.01 sec - 99.99 sec
X.X.X.X (All decimal points illuminated): Timing range: 1 min - 9999 min

For example, to set the OP to 3.2 seconds, move the decimal point to the tens position; the LCD will display "003.2".

Wiring Diagrams

The module supports both weak current control and strong current wiring configurations, allowing for flexible integration into various systems.

Weak Current Control / Strong Current Wiring Diagram

This diagram illustrates the connection of the power supply (either Micro USB 5.0V or a 6.0V-30V source) to the module's power input terminals. Trigger signals are connected to the designated input pins: High level trigger (+), Signal GND, and Low level trigger (-). The relay output terminals (NC - Normally Closed, COM - Common, NO - Normally Open) are used to connect to the load, with the load typically wired between COM and either NC or NO.

Wiring Diagram for Sharing One Power Supply

This diagram depicts a setup where a single power supply serves both the timer relay module and the controlled load. Connections are made to the appropriate power input terminals on the module and to the load via the relay output terminals.

Remote Data Uploading and Parameter Setting Functions

The system is capable of UART data uploading and parameter setting via a TTL interface. The default UART communication settings are: baud rate 9600, 8 data bits, and 1 stop bit. Users can utilize specific commands (CMD) to read system parameters, set operating time (OP), close time (CL), loop times (LP), and manage relay enable/disable states. Different commands are available for various timing ranges, such as OP:XXXX for the 1-second range and OP:XXX.X for the 0.1-second range.

Additional Functions

Auto Sleep/Low Power Function: In the running interface, a long press of the STOP key enables or disables the auto sleep function. The setting is indicated by "L-P ON" (enable) or "L-P OFF" (disable).
Relay Enable/Disable Function: A short press of the STOP key in the running interface allows the user to enable or disable the relay's operation. "ON" signifies that the relay will activate when its conduction conditions are met. "OFF" means the relay will not activate even if conditions are met, and the display will show "OUT" flashing.
Parameter Viewing: A short press of the SET key in the running interface displays the current system parameters without affecting the ongoing operation.
Display Content Switching: For modes P5 and P6, a short press of the DOWN key allows switching the displayed content between the running time and the loop times.

Parameter Setting Procedure

To enter the setting interface, press and hold the SET key.
Set the desired working mode by pressing the UP/DOWN keys; the selected mode will flash to indicate it.
Short press the SET key to confirm the working mode selection and proceed to the system parameter setting interface.
Within the system parameter setting interface, short press the SET key to cycle through the parameters that can be changed. Use the UP/DOWN keys (short or long press) to adjust the values. Note: Short pressing the SET key is not functional in modes P1-P3 and P7.
When setting OP/CL parameters, short press the STOP key to switch the timing unit between 1s, 0.1s, 0.01s, and 1min.
After all parameters have been set, press and hold the SET key to save the configurations and exit the setting interface.
