Feature: 1. Compatibility: The industrial grade serial module supports USB to RS422, USB to RS485, USB to TTL (UART), and TTL to RS422/RS485 communicating. The circuit operates on a 5V power supply, with TTL signal output levels at 5V, compatible with both 3.3V and 5V signal inputs. 2. FT232RL Chip: The industrial grade serial module features an original FT232RL chip, ensuring stable, and high speed communicating with excellent compatibility. Encased in an aluminum alloy shell with an oxidized matte finish and precise aperture design, the module is sturdy, aesthetically pleasing, and well crafted. 3. Simple Operating: The industrial grade serial module is user friendly, capable of automatic sending and receiving conversion. With fast, stable, and secure communicating capabilities, it is suitable for various industrial control devices or applications requiring high communicating standards. 4. On Board TVS: Equipped with on board TVS (Transient Voltage Suppression) diodes, the module effectively suppresses surge voltages and transient peaks in the circuit, protecting downstream circuits and devices. Featuring on board self recovery fuses to ensure stable current and voltage output, preventing overcurrent, overvoltage, electrostatic discharge, and providing strong surge protect. 5. On Board GDT Gas Discharge Tube: With on board GDT gas discharge tubes, powerful lighting currents can be discharged into the ground, preventing subsequent circuits and devices from being damaged by surge impacts. Additionally, the on board digital isolator offers excellent performance characteristics and reliability, enabling signal isolation and ensuring more stable signal transmission. 6. On Board DC/DC Power Isolation: The on board DC/DC power isolation provides stable isolated voltages and output short circuit protect, eliminating the need for additional power supply to the isolation end. Featuring an on borad automatic sending and receiving conversion circuit, it ensures quick and stable communicating between the USB end and different interfaces without interference.
