GODIYMODULES Adjustable Cycle Timer Delay Relay Module

Introduction

The GODIYMODULES Mod-JK11Relay-001 is a versatile DC 12V adjustable cycle timer delay relay module designed for various timing control applications. It features both single time mode and cycle mode operations, allowing precise control over connected devices. This manual provides detailed instructions for setup, operation, and troubleshooting to ensure optimal performance.

Safety Information

• Ensure the power supply is DC 12V as specified. Incorrect voltage can damage the module.
• Disconnect power before making any wiring connections or adjustments.
• Observe proper polarity when connecting the DC 12V power supply.
• The relay output supports up to 10A. Do not exceed this current rating to prevent damage.
• Avoid exposing the module to moisture, extreme temperatures, or corrosive environments.
• If you are unsure about any wiring or operation, consult a qualified technician.

Product Overview

The Mod-JK11Relay-001 module integrates a microcontroller for high time precision. It includes a watchdog circuit and a dedicated reset chip for stable and reliable operation. Key components include a relay, potentiometers for time adjustment, and jumpers for mode selection.

Figure 1: Module Components. This image displays the main components of the relay module, including the blue relay, two adjustable potentiometers (R4 and R5), and two jumper pins (J4 and J5) for mode selection.

Specifications

Setup and Wiring

Proper wiring is essential for the correct and safe operation of the module. Refer to the diagram below for connection points.

Figure 2: Wiring Diagram. This diagram illustrates how to connect the DC 12V power supply, the load (AC or DC), and identifies the relay output terminals (Common, Normally Open, Normally Closed), power indicator, relay indicator, and the T1/T2 adjustment potentiometers.

1. Power Supply: Connect a DC 12V power source to the '+' and '-' terminals on the module. Ensure correct polarity.
2. Load Connection: The relay has three terminals:
   • Common (COM): The central terminal.
   • Normally Open (NO): Connected to COM when the relay is active (ON).
   • Normally Closed (NC): Connected to COM when the relay is inactive (OFF).
   Connect your load (device to be controlled) to the COM and either NO or NC terminals, depending on your application's requirements (e.g., COM and NO for a device that turns ON when the relay is active). The relay can handle AC loads up to 250V/10A or DC loads up to 30V/10A.
3. Trigger Button: Connect an external trigger button to the designated "Button Turn on/Turn off" terminals (white wires). Shorting these wires will activate the module. For auto-start at power-on, these wires can be permanently shorted.

Operating Modes and Adjustments

The module supports two primary operating modes: Single Time Mode and Cycle Mode. These modes, along with time ranges, are configured using jumpers and potentiometers.

Figure 3: Jumper Settings. This image highlights the positions for setting the module to 'Single' mode, 'Loop' (Cycle) mode, and activating the 'Acceleration' feature for faster time adjustment.

1. Mode Selection (Jumper J5)

• Single Time Mode: Set Jumper J5 to "Single" (UP position).
• Cycle Mode: Set Jumper J5 to "Loop" (DOWN position).

2. Time Range Selection (Jumper J4)

Jumper J4 controls the overall time range for the potentiometers.

• Normal Range: Set Jumper J4 to "Normal" (UP position). This corresponds to the OP2 range (1 second to 15 minutes).
• Acceleration Range: Set Jumper J4 to "Acceleration" (DOWN position). This activates a faster time range, typically 0-1.5 minutes, for quicker adjustments and testing. This corresponds to the OP1 range (1 second to 100 seconds).

Note: The specific time ranges for OP1 and OP2 are determined by the jumper settings. Refer to the Specifications section for detailed ranges.

3. Time Adjustment (Potentiometers T1 and T2)

Two adjustable potentiometers (T1 and T2, also labeled R4 and R5 in some diagrams) are used to set the delay times. Turning them clockwise increases the time.

• T1 (R4): Adjusts the "ON" time or initial delay.
• T2 (R5): Adjusts the "OFF" time in Cycle Mode.

Detailed Operating Modes:

Single Time Mode (J5 set to "Single")

1. After power-on, the relay remains OFF.
2. Upon triggering (shorting the button terminals), the relay turns ON.
3. After the set time (T1) has elapsed, the relay turns OFF.
4. If triggered again during the delay process, the current delay is immediately interrupted, and a new cycle begins.

Cycle Mode (J5 set to "Loop")

1. After power-on, the relay remains OFF.
2. Upon triggering (shorting the button terminals), the relay turns ON for the duration of T1.
3. After T1, the relay turns OFF for the duration of T2.
4. This ON-OFF cycle (T1 ON, T2 OFF) repeats indefinitely until triggered again to stop, or power is removed.
5. If triggered again during the delay process, the current delay is immediately interrupted, and the cycle stops.

Troubleshooting

• Module not powering on:
  • Check DC 12V power supply connections and ensure correct polarity.
  • Verify the power supply is providing 12V DC.
• Relay not activating/deactivating:
  • Ensure the trigger button is correctly wired and functioning.
  • Check jumper settings for the selected operating mode (Single/Cycle).
  • Verify potentiometer settings are not at their minimums if a delay is expected.
  • Confirm the load is correctly connected to the COM and NO/NC terminals.
• Incorrect timing:
  • Adjust potentiometers T1 and T2.
  • Check Jumper J4 setting for the correct time range (Normal/Acceleration).
  • Ensure the power supply is stable. Fluctuations can affect timing accuracy.
• Module burned out/smoking:
  • Immediately disconnect power.
  • This indicates a severe issue, likely incorrect voltage, reversed polarity, or exceeding the relay's current rating. The module may need replacement.

Maintenance

The Mod-JK11Relay-001 module requires minimal maintenance. Follow these guidelines to ensure longevity:

• Keep the module clean and free from dust and debris. Use a soft, dry cloth for cleaning.
• Ensure adequate ventilation if operating in an enclosed space to prevent overheating.
• Regularly inspect wiring connections for looseness or corrosion.
• Store the module in a dry, cool environment when not in use.
