1. with RS232/RS485 standard, can convert RS232 signal to balanced differential RS485 signal. 2. The transmission speed is stable and the reliable communication speed is 300~115200bps. 3. Built-in isolation can stabilize the isolation voltage without additional supply at the isolation end 4. Built-in digital isolation, signal isolation, high reliability, strong anti-interference and low consumption. 5. On-board TVS (transient voltage suppressor) can effectively suppress overvoltage and transient voltage ietsen, and prevent- and static Features: Short-mounted recovery fuse and protection diode can stabilize the output power of current and voltage, prevent overvoltage and overvoltage and impact resistance. Built-in RS485 output terminal 120R resistor, which can be connected for easy operation supply interface for built-in terminal, supports supply in a wide voltage range of 6~36V DC Industrial rail type V0 - retardant shell, small size, convenient installation, cost-effective Specifications: Product type: digital isolated RS232 to RS485 serial port converter supply voltage: 6~36V DC Interface protection: anti reverse connection Reliable communication speed: 300 ~115200bps Equipment interface: with RS232/RS485 standards RS232 interface: Interface type: terminal block Transmission distance: about 15m Transmission mode: -to- RS485 interface: Interface type: terminal block Direction control: hardware automatically judges and controls the direction of data transmission Interface protection: 600W protection, overvoltage protection and 15KV static protection Terminal resistance: 120R, which can be activated by switch Transmission distance: approx. 1200m Transmission mode: to many (32 nodes at , and repeaters are recommended for more than 16 nodes) Shell: rail type V0 - 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 contents, other products are not included.
