Instructions

1. Supply Voltage:

   • The DG403DJ can operate with a dual supply ranging from 卤5V to 卤18V or a single supply from 10V to 36V. Ensure the supply voltage is within these ranges to avoid damage to the device.

2. Signal Path:

   • The signal path is between the Common (COM) pin and either the Normally Open (NO) or Normally Closed (NC) pins, depending on the control input.
   • Connect the signal source to the COM pin and the load to either the NO or NC pin as required.

3. Control Input:

   • The control input (IN) determines the state of the switch. Apply a high logic level to connect COM to NO, and a low logic level to connect COM to NC.
   • The control input should be within the supply voltage range to ensure proper operation.

4. Powering the Device:

   • Connect the positive supply voltage to the V+ pin and the negative supply voltage to the V- pin.
   • For single supply operation, connect the positive supply to V+ and ground to V-.

5. Handling and Storage:

   • Handle the DG403DJ with care to avoid static discharge, which can damage the device.
   • Store the device in a dry, cool place away from direct sunlight and corrosive environments.

6. Mounting:

   • Solder the device to the PCB following standard surface mount technology (SMT) procedures.
   • Ensure all connections are secure and free from shorts or open circuits.

7. Testing:

   • After mounting, test the device by applying a known signal to the COM pin and verifying the output at the NO or NC pin based on the control input.
   • Use an oscilloscope or multimeter to measure the signal integrity and switch performance.

8. Troubleshooting:

   • If the switch does not function as expected, check the supply voltages, control input levels, and connections for any issues.
   • Refer to the datasheet for more detailed troubleshooting tips and specifications.
