TTL To RS485 Isolated Converter DIN-Rail
DIN Rail-Mount TTL To RS485 Galvanic Isolated Converter, 600W Lightningproof & Anti-Surge, Multi-Isolation Protection
Features:
- Compatible with TTL/RS485 standard, converting the TTL signal into differential RS485 signal, supporting half-duplex communication
- Compatible with 3.3V ~ 5V TTL signal level, provides anti-reverse and 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, lightning proof & anti-electrostatic
- Onboard resettable fuse and protection diodes, ensures the current/voltage stable outputs, provide over-current/over-voltage protection, improve shock resistance
- Onboard RS485 output terminal 120R resistor, enabled/disabled via switch
- Industrial rail-mount ABS case design, small in size, easy to install, and cost-effective
