1. Compatible with RS232/RS485 standard, converts RS232 signals to balanced differential RS485 signals. 2. Stable transmission rate with reliable communication speed of 300–115200 bps. 3. Onboard integrated power isolation provides stable isolation voltage without requiring an external power supply at the isolated end. 4. Onboard digital isolation for signal separation, offering high reliability, strong interference resistance, and low power consumption. 5. Onboard TVS (transient voltage suppressor) effectively suppresses surge and transient voltages, providing protection against lightning and static electricity. Features: - Board-mounted self-recovery fuse and protective diode ensure stable current and voltage output, prevent overvoltage, and improve surge resistance. - Onboard RS485 output terminal includes a 120Ω resistor that can be enabled or disabled via switch for easy operation. - Onboard power supply interface supports wide DC voltage input range of 6–36V. - Industrial-grade rail-mountable V0 flame-retardant housing, compact size, easy installation, and cost-effective design.
