AJMRTC industrial USB to RS232/485/TTL isolated converter adopts FT232RL chip as the core control unit. It can convert USB signal into RS232, RS485 and TTL serial signals in one module. The isolation design protects connected devices from voltage surge and ground loop interference, greatly improving stability in noisy industrial sites. It draws power directly from USB port without extra power supply. This multi-protocol serial converter works great for PLC debugging, industrial sensor communication and embedded device testing. It comes with necessary driver resources for quick setup.
