Rail-Mount TTL To RS485 (B)

Galvanic isolated Serial Port Converter

Features At A Glance

• 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

Specifications

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

Multiple Protection, Safe And Stable

Onboard power and signal isolation, provide stable isolated voltage, high reliability and strong anti-interference. Onboard Lightningproof Diodes and TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightningproof & anti-electrostatic. Onboard resettable fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage protection, improves shock resistance
