| Product Name | Optical Isolation Unit |
| Interface Type | RS232C Input |
| Model Number | MEW-153A |
| Part Number | CBG-0505 |
| Function | Electrical Signal Isolation for RS232C Communication |
| Weight | 580 gm |
Optical Isolation Unit MEW-153A / CBG-0505 is a key interface unit that has been specifically made to offer galvanic isolation between equipments communicating via RS232C serial interfaces. It serves as a buffer guaranteeing the security and stability of the installed equipment by isolated electrical signals between the sending and receiving ends via optical means.

Features:
• RS232C Interface Compliance: Fully compliant with RS232C serial communication standards found on computers, PLCs, HMIs, and industrial controllers.
• Total Electrical Isolation: Uses optical coupling to completely isolate the transmitting and receiving devices, removing the possibility of ground loops and surges.
• Improved Equipment Protection: Stops signal path contamination, electrical faults, and overvoltage conditions from reaching connected devices.
• Noise Rejection: Provides high immunity to electrical noise and EMI, ensuring clean and accurate signal transmission.
• Space-Saving Durable Design: Small, rugged form factor ideal for control panels, communication boxes, and system enclosures.
• Plug-and-Play Integration: Easy to integrate into current RS232C-based systems without the need for complicated setup.
Applications:
1. Industrial Automation Systems: Applied to isolate PLCs, sensors, and operator interfaces (HMIs) that exchange signals over RS232C, providing safe signal transfer.
2. Marine Communication Equipment: Safeguards navigation systems, onboard computers, and monitoring units against signal interference and ground potential differences.
3. SCADA and Remote Monitoring: Guarantees safe transmission of data between central monitoring software and remote terminal units (RTUs) through RS232 interfaces.
4. Laboratory & Testing Equipment: Protects test benches and lab instruments from static discharge or cross-talk while capturing data.
5. Process Control Applications: Facilitates uninterrupted, safe communication among controllers, actuators, and legacy systems in power, chemical, and utility industries.
6. Embedded System Development: Utilized by engineers to safely debug or communicate with embedded systems during diagnostics and development.
This unit is constructed for reliable data transfer, without vulnerabilities such as ground loops, voltage spikes, and electromagnetic interference (EMI) that can destroy sensitive hardware or lead to data corruption. Optical isolation actually isolates devices, allowing secure and unbroken communication in harsh industrial and naval environments.
