Galvanic Isolated TTL to RS485

Bezeichnung bei Amazon: Galvanic Isolated TTL to RS485 (C) Converter Module Point-to-Point Half-Duplex Communication 3.3V ~ 5V TTL Signal Level 200W Iightningproof and Surge-Suppress 6KV ESD Protection

• TTL to RS485 converter: TTL to RS485 board compatible with TTL/RS485 standard, converting the TTL signal into differential RS485 signal, supports half-duplex communication. Compatible with 3.3V ~ 5V TTL signal level, provides over-voltage protection for power supply interface
• Power & Digital Dual Isolation: TTL to RS485 module onboard unibody power supply isolation, provides stable isolated voltage and needs no extra power supply for the isolated terminal Onboard unibody digital isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption
• Onboard TVS: TTL to RS485 adapter module onboard TVS (Transient Voltage Suppressor), effectively suppresses surge voltage and transient spike voltage in the circuit, lightningproof & anti-electrostatic Onboard self-recovery fuse and protection diodes, ensures the current/voltage stable outputs, provide over-current/over-voltage protection, improve shock proof performance
• 120R resistor terminals: TTL to RS485 adapter module onboard RS485 output terminal 120R resistor, enabled via soldering; Black immersion gold process design, compact size, easy to integrate
