1. Compatible with RS232/RS485 standard, can convert RS232 signal into balanced differential RS485 signal. 2. The transmission rate is stable, and the reliable communication rate is 300~115200bps. 3. On board integrated power isolation can provide stable isolation voltage without additional power supply at the isolation end 4. On board integrated digital isolation, signal isolation, high reliability, strong anti-interference and low power consumption. 5. On board (transient voltage suppressor) can effectively suppress surge voltage and transient voltage in the circuit, and prevent- and static electricity features: Board mounted self recovery fuse and protective diode can stable output of current and voltage, prevent over-voltage and over-voltage, and improve impact resistance. On board RS485 output terminal 120R resistor, which can be switched on and off for easy operation Power supply interface of on-board terminal, supporting power supply in a wide voltage range of 6~36V DC Industrial guide rail type V0 flame-retardant shell, small size, convenient installation, cost-effective : Product type: active digital isolated RS232 to RS485 serial port converter Power supply voltage: 6~36V DC Interface protection: anti reverse connection Reliable communication rate: 300~115200bps Equipment interface: compatible with RS232/RS485 standards RS232 interface: Interface type: terminal block Transmission distance: about 15m Transmission mode: point-to-point RS485 interface: Interface type: terminal block Direction control: hardware automatically judges and controls data transmission direction Interface protection: provide 600W protection, surge protection and 15KV static protection Terminal resistance: 120R, which can be enabled through switch switching Transmission distance: about 1200m Transmission mode: point to many (32 nodes at most, and repeaters are recommended for more than 16 nodes) Shell: rail type V0 flame-retardant shell Size: 91.6 x 23.3 x 58.7mm color: White Material: ABS Package Contents: 1 x RS232 to RS485 converter Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
