1. Compatible with RS232/RS485 standard, converts RS232 signal to balanced differential RS485 signal. 2. Stable transmission rate with reliable communication speed of 300–115200 bps. 3. Onboard integrated isolation provides stable isolation voltage without requiring additional power supply on the isolation side. 4. Onboard digital isolation ensures signal isolation, high reliability, strong anti-interference performance, and low power consumption. 5. Onboard TVS (transient voltage suppressor) effectively suppresses surge and transient voltages, protecting against electrical surges and static electricity. Features: - Board-mounted self-recovery fuse and protective diode ensure stable current and voltage output, protect against overvoltage, and improve impact resistance. - Onboard RS485 output terminal includes a 120R resistor that can be switched on or off for easy operation. - Onboard terminal power interface supports wide DC input voltage range of 6–36V. - Industrial rail-mount design with V0 flame-retardant housing, compact size, and easy installation.
