Galvanic Isolated Converter

Castellated Holes With Immersion Gold process, Compact size, Easy to integrate

Features At A Glance

• 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
• 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 (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
• Onboard RS485 output terminal 120R resistor, enabled via soldering
