TTL to RS485 Electrical Isolation Module DIN Rail Serial Converter Stable Communication 600W Lightning Protection
Features:
1. Compatible with TTL/RS485 standard, it can convert TTL signals into differential RS485 signals, half-duplex communication
2. Compatible with 3.3V ~ 5V TTL signal level, power supply terminal has anti-reverse and anti-overvoltage circuit
3. On-board integrated power supply isolation can provide stable isolation voltage, and the isolation terminal does not require additional power supply
4. On-board integrated digital isolation, which can perform signal isolation, with high reliability, strong anti-interference and low power consumption.
5. On-board TVS (Transitute Voltage Suppression Pipe) can effectively suppress surge voltage and transient spike voltage in the circuit, and prevent lightning and static electricity.
6. On-board self-recovery fuse and protection diode can ensure stable output of current and voltage, prevent overcurrent and overvoltage, and improve impact resistance
7.On-mounted RS485 output terminal 120R resistor, switchable and enable, easy operation
8. Industrial rail-type ABS environmentally friendly shell, small size, easy to install, and high cost performance
