Key Components:

• LCD Display: Shows current mode, timing parameters (OP, CL, LOP), and status.
• Control Buttons:
  • SET: Enters/exits parameter setting mode, confirms selection.
  • UP/DOWN: Adjusts parameter values, navigates menus.
  • STOP: Stops the current operation, enables/disables relay output.
• Power Input Terminals: DC 6-30V.
• Micro USB Port: Alternative 5V power supply.
• Relay Output Terminals: Normally Open (NO), Normally Closed (NC), Common (COM).
• Trigger Input: High level trigger (3.0V-34V) and low level trigger (0V-0.2V).

Setup

Before connecting the module, ensure all power sources are disconnected.

1. Power Connection:
   • For DC 6-30V power, connect the positive (+) and negative (-) wires to the corresponding input terminals on the module.
   • Alternatively, for 5V power, connect a Micro USB cable to the Micro USB port.
2. Load Connection:
   • Connect your load (e.g., light, motor) to the relay output terminals (NO, NC, COM) based on your application's requirements.
     • Normally Open (NO): The circuit is open when the relay is de-energized and closes when energized.
     • Normally Closed (NC): The circuit is closed when the relay is de-energized and opens when energized.
     • Common (COM): The common terminal for the relay switch.
3. Trigger Connection (Optional):
   • If using an external trigger, connect the trigger signal to the designated trigger input terminal. The module supports both high-level (3.0V-34V) and low-level (0V-0.2V) triggers.

Operating Instructions

The module supports various operating modes and programmable parameters.

Parameter Settings:

Press the SET button to enter parameter setting mode. The LCD will display the current mode (e.g., P-1.1). Use UP/DOWN to navigate between modes and adjust values. Press SET again to confirm and move to the next parameter or exit.

• OP: Turn-on time (0.01s - 9999mins).
• CL: Turn-off time (0.01s - 9999mins).
• LOP: Number of cycles (1-9999, "---" for infinite loop).

All setting parameters are automatically saved upon power-off.

Operating Modes:

The module offers multiple operating modes (P-1.1 to P-4), each with specific functionalities. Refer to the LCD display for the current mode.

STOP Button Functionality:

In the main interface, short press the STOP button to switch between ON and OFF states for the relay output. This function allows for immediate control of the connected load.

Maintenance

The ACEIRMC Time Delay Relay module requires minimal maintenance.

• Keep the module clean and free from dust and debris. Use a soft, dry cloth for cleaning.
• Ensure all wiring connections remain secure. Periodically check for loose terminals.
• Avoid exposing the module to extreme temperatures, humidity, or corrosive substances.
• Do not attempt to disassemble the module beyond what is necessary for wiring.
