Uvod
The BARRINS GLG Signal Isolator is designed to provide isolated power distribution for transmitters, while simultaneously isolating and converting current signals for control systems such as PLCs and DCS. This device ensures signal integrity and system protection through its advanced isolation technology.
It supports common current sources, 2-wire, and 3-wire input terminals. The input, output, and power circuits are mutually isolated using highly efficient magnetoelectric isolation technology. The isolator operates on a DC 24V or AC 85-265V power supply and is designed for standard 35mm DIN rail mounting, offering strong anti-interference capabilities and versatility.
Nastavitev in namestitev
Before installation, ensure the power supply is disconnected to prevent electrical hazards.
- Montaža: Mount the GLG Signal Isolator onto a standard 35mm DIN rail. The device is designed for independent mounting.
- Vhodno ožičenje: Connect the input signal wires to the designated input terminals. This model supports 2 inputs. Refer to the wiring diagram for specific terminal connections.
- Izhodno ožičenje: Connect the output signal wires to the designated output terminals. This model provides 2 outputs. Refer to the wiring diagram for specific terminal connections.
- Priključek za napajanje: Connect the power supply (DC 24V or AC 85-265V) to the power terminals. Ensure correct polarity for DC power.
Refer to the following images for visual guidance on installation and wiring:

Delovanje
Once correctly installed and powered, the GLG Signal Isolator will automatically begin processing signals. It converts and isolates the input signal (0-10mA for this model) into the specified output signal (0-5V for this model) for your control system. No user configuration is typically required for standard operation once the correct model is selected for your application.
Vzdrževanje
To ensure the longevity and reliable performance of your GLG Signal Isolator, follow these maintenance guidelines:
- Regularly inspect the device for any signs of physical damage, such as cracks or loose connections.
- Keep the isolator clean and free from dust, dirt, and moisture. Use a soft, dry cloth for cleaning.
- Za preprečitev poslabšanja delovanja zagotovite, da temperatura in vlažnost delovnega okolja ostaneta znotraj določenih razponov.
Odpravljanje težav
If the GLG Signal Isolator is not functioning as expected, consider the following troubleshooting steps:
- Brez napajanja: Verify that the power supply is correctly connected and within the specified voltage range (DC 24V or AC 85-265V). Check power indicator lights if available.
- Nepravilno ožičenje: Double-check all input and output wiring for correct connections and polarity according to the wiring diagram.
- Signal Mismatch: Confirm that the input signal type and range (0-10mA) match the isolator's specifications and that the output device is compatible with the isolator's output (0-5V).
- Okoljski dejavniki: Ensure the operating temperature and humidity are within the specified limits.
- If issues persist after performing these checks, consult a qualified technician or contact customer support.
