Dual Channel UART Serial RS232/TTL Converter (Terminal to Terminal)
Original price was: 125.00 EGP.110.00 EGPCurrent price is: 110.00 EGP.
Two-channel RS232 to TTL (UART) level converter with screw terminals on both sides. Connects microcontrollers and modules to RS232 devices such as PLCs, HMIs and serial instruments.
The Dual Channel UART Serial RS232/TTL Converter (Terminal to Terminal) converts RS232 voltage levels to 3.3V/5V TTL UART levels on two independent channels. Both sides use screw terminals, so you can wire it straight into control panels and industrial equipment without soldering or extra connectors.
Dual Channel UART Serial RS232/TTL Converter (Terminal to Terminal) – Key Features
- Two independent RS232 ↔ TTL UART channels
- Screw terminals on the RS232 side and the TTL side
- Works with 3.3V and 5V logic (check the supply pin marking)
- TX, RX and GND on each channel
- Compact board for panel and DIN-box mounting
Applications
Makers, students and technicians use it in many kinds of projects, for example:
- Connecting Arduino, ESP32 or Raspberry Pi to RS232 devices
- PLC and HMI serial communication
- Reading serial scales, meters and barcode scanners
- Industrial and lab equipment interfacing
- Replacing failed serial interface boards
Usage Tips
Never connect RS232 lines directly to a microcontroller pin; RS232 can swing to ±12V. Cross TX and RX between devices, share a common GND, and power the board from the same logic voltage as your microcontroller.
