TTL to RS485 Converter Module 5V Industrial Serial Port UART to 485 Adapter Module On Board TVS with Indicator Light

Feature: 1. Built in Transient Voltage Suppression: TTL to RS485 module features built in TVS to effectively suppress surge and transient voltage, protecting circuit and equipment. Adopt 5.08mm standard terminal block, easy plugging and unplugging. 2. Self Recovery Fuse Guard: Equipped with self recovery fuse to ensure stable output of current and voltage, offering over current and over voltage prevention, as well as strong anti shock capability. 3. On Board Gas Discharge Tube: Integrated with GDT to redirect powerful thunder current to the ground, preventing subsequent circuits and equipment from damage caused by surges. 4. On Board Digital Isolator: The module includes a digital isolator with outstanding performance and reliability, enabling signal isolation for more stable transmission of signals. 5. DC DC Power Isolation: Features DC DC power isolation to provide stable isolation voltage and output short circuit prevention, without the need for additional power supply to the isolated terminals. Specification: Item Type: TTL to RS485 Module Material: PCB Operating Voltage: 5.0V Signal: 5.0V Baud Rate Support Range: RS485: <1Mbps (non standard value, refer to the baud rate range of the devices at both ends in actual use) Indicator Light: Green indicator: Module power indicator, always on when the module is powered on White indicator (near RXD interface): TTL terminal receive signal indicator, that is, the signal flow for TTL to 485, the LED blinks White indicator (near TXD interface): TTL terminal send signal indicator, that is, the signal flow direction is 485to TTL, the LED blinks . Package List: 1 x TTL to RS485 Adapter Module 2 x Terminal 1 x Screwdriver
