TTY 20mA Currentloop to fiber optic converters, DL-TTY

The DL TTY system is a versatile solution that forms an asynchronous TTY (Teletypewriter) interface, supporting 20 mA active, half-active, or passive configurations. This innovative system offers operational flexibility, accommodating both half-duplex and full-duplex modes, as depicted in the accompanying schematics. The system provides adaptability for diverse communication requirements in industrial settings.

Designed to interface with TTY devices, the DL TTY system employs singlemode and multimode fiber optic technology, ensuring compatibility with various optical configurations. This flexibility allows the system to cater to different communication distances and requirements within industrial applications. Singlemode fiber optics are suitable for long-distance communication, while multimode fiber optics are ideal for shorter-distance transmissions.

LED indicators integrated into the DL TTY system serve as visual indicators for monitoring the operational status of the TTY interface. Additionally, the system includes optional potential-free contacts in a fault detector relay, enhancing its capability to signal and respond to defective states. This proactive monitoring system contributes to the reliability and maintenance of the communication network.

Whether configured for half-duplex or full-duplex operation, the DL TTY system provides a reliable and adaptable solution for asynchronous TTY interfaces, meeting the communication needs of industrial environments. The incorporation of fiber optics, LED indicators, and fault detection features makes the DL TTY system a comprehensive and efficient choice for industries requiring robust and flexible communication solutions.
