USB to RS232/RS485/TTL converter with isolation built on FT232RL

Description:

USB to RS232/RS485/TTL converter with full isolation based on the original FT232RL chip. It has built-in protection circuits including galvanically separated power supply circuits.

The module is very easy to use and has fully automated processes for transmitting and receiving data without delay. Due to its data transfer rate, stability and reliability, it is ideal for industrial applications.

Features:

• USB to RS232, USB to RS485, USB to TTL (UART)
• Includes original FT232RL, fast communication, stability and reliability.
• Galvanically separated power supply circuits. No need for external power circuits.
• Includes reliable magnetic isolation which greatly improves noise immunity.
• Includes TVS (Transient Voltage Suppressor) overvoltage protection, suppresses overvoltages, steep voltage spikes and electrostatic spikes very effectively.
• Includes overload protection. Resettable fuses and protection diodes on board.
• Fully automatic transceiver with no delay in transmitted data.
• Includes 3.3V/5V voltage level translator, TTL level configuration via switch.
• Robust aluminium housing.
• LED indicators for power monitoring and transmission status.
• High-quality USB and RS232 connectors.
