Χαρακτηριστικά

Rail-Mount TTL To RS485 Galvanic Isolated Converter, 600W Lightningproof & Anti-Surge, Multi-Isolation Protection

Rail-Mount TTL To RS485 (B)
Galvanic isolated Serial Port Converter

Compatible with TTL/RS485 standard, converting the TTL signal into differential RS485 signal, support 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, lightningproof & 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

Primary Function
Converting The TTL Signal Into Balanced Differential RS485 Signal
For Interface Converting, Expanding Nodes And Long-Distance Communication

Rail-Mount Support
Easy To Combine Multi Rail-Mounted Serial Server Together, More Freely
