4. Setup u Wiring
Proper wiring and DIP switch configuration are essential for correct operation. Refer to the images below for terminal identification and DIP switch settings.
4.1 Konnessjonijiet Terminali
The module features screw terminals for input and output connections. Ensure all connections are secure.
- Input Terminals (IN1+ to IN8+ / IN1- to IN8-): Connect your NPN or PNP input signals here. Each channel has a positive (+) and negative (-) input.
- Power Input (V+, GND): Connect the main power supply for the module.
- Output Terminals (5V GND, 24V GND, 5V1-5V8, 24V1-24V8): These are the NPN-OC outputs. Connect your load to the appropriate 5V or 24V output and its corresponding GND.

4.2 Konfigurazzjoni tal-Iswiċċ DIP
The red DIP switch block (SW1 to SW8) controls the input voltage level for each of the 8 channels. Each switch corresponds to one channel (SW1 for Channel 1, SW2 for Channel 2, etc.).
- Ixgħel il-Pożizzjoni: Set the corresponding channel to accept a 5V input level.
- Aqleb il-Pożizzjoni OFF: Set the corresponding channel to accept a 24V input level.
Ensure all DIP switches are set correctly according to the input voltage levels of your signals before applying power.

5. Istruzzjonijiet Operattivi
Once the module is correctly wired and the DIP switches are configured for the desired input voltage levels, apply power to the V+ and GND terminals. The module will then convert the input signals according to its configuration.
- Input Signal Application: Apply your NPN or PNP signals to the respective IN+ and IN- terminals for each channel.
- Output Signal Retrieval: The converted NPN-OC signals will be available at the 5V1-5V8 or 24V1-24V8 output terminals, depending on the desired output level. Connect your receiving circuit or load to these outputs.
- Iżolament tal-optocoupler: The integrated optocouplers provide electrical isolation between the input and output circuits, protecting sensitive components and improving noise immunity.
6. Manutenzjoni
The Yunir Level Converter Module is designed for reliable operation with minimal maintenance. Follow these guidelines to ensure longevity:
- Ambjent: Operate the module in a clean, dry environment, free from excessive dust, moisture, and corrosive gases.
- Temperatura: Avoid exposing the module to extreme temperatures outside its specified operating range.
- Provvista tal-Enerġija: Ensure a stable and correctly rated power supply is used to prevent damage.
- Konnessjonijiet: Periodically check all screw terminal connections to ensure they remain tight and secure.
- Tindif: If necessary, gently clean the module with a soft, dry cloth. Do not use liquid cleaners or solvents.
7 Issolvi l-problemi
If you encounter issues with the module, consider the following troubleshooting steps:
- L-ebda Sinjal tal-Ħruġ:
- Verify that the power supply (V+, GND) is correctly connected and providing the specified voltage.
- Check all input and output wiring for correct polarity and secure connections.
- Ensure the DIP switches for the affected channels are set correctly for the input voltage level (ON for 5V, OFF for 24V).
- Confirm the input signal is present and within the expected voltagfirxa e.
- Volum tal-Ħruġ Mhux Korretttage/Level:
- Re-check the DIP switch settings for the specific channel. An incorrect setting will lead to improper conversion.
