Compatible with RS232/RS485 standard, converts RS232 signals to balanced differential RS485 signals. Features a stable transmission rate with reliable communication speed ranging from 300 to 115200 bps. Integrated power isolation provides stable isolation voltage without requiring an external power supply at the isolated end. Built-in digital signal isolation ensures high reliability, strong anti-interference performance, and low power consumption. Equipped with TVS (transient voltage suppressor) to effectively suppress surge and transient voltages, offering protection against lightning and static electricity. Onboard self-resetting fuse and protective diodes ensure stable current and voltage output, prevent overvoltage, and enhance impact resistance. Onboard 120 ohm terminal resistor for RS485 output, switchable for convenient operation. Onboard power supply terminal supports wide DC voltage input range from 6 to 36V. Industrial-grade rail-mountable design with V0 flame-retardant housing, compact size, and easy installation.
