EXSYS EX-47200 Conversor RS-232 para TTL com níveis selecionáveis de 3,3V/5V

Embedded developers and industrial integrators often need to connect legacy RS-232 equipment to modern TTL-based microcontrollers or sensors. The EXSYS EX-47200 bridges that gap with a compact converter that handles both 3.3V and 5V logic levels. It features a DB9 male RS-232 port and a 5-pin terminal block for TTL signals, making it simple to wire into custom projects or test setups.

Key specifications

• Converts RS-232 to TTL (Transistor-Transistor Logic)
• Selectable TTL voltage: 3.3V or 5V
• RS-232 connector: 1x DB9 male
• TTL connector: 1x 5-pin terminal block
• Maximum data rate: 230.4 Kbps
• Powered from RS-232 port (DTR/RTS) or external 5V DC
• LED indicators for power, TxD, and RxD
• Operating temperature: -20°C to 70°C
• Housing material: plastic

Why choose it

The EX-47200 offers flexible power options and clear status LEDs, which simplify troubleshooting during development. Its wide operating temperature range makes it suitable for both lab and field use.

Ideal use cases

• Interfacing legacy RS-232 devices with TTL-based microcontrollers
• Industrial automation and control systems
• Prototyping and testing embedded systems

Good to know

The terminal block includes VCC and VIO pins for external power and voltage reference, giving you precise control over signal levels.
