Product Features
Compatible with TTL/RS232 standards, it can convert TTL signals to RS232 signals and supports full-duplex communication.
Compatible with 3.3V ~ 5V TTL signal levels, the power supply terminal is equipped with anti-reverse connection and over-voltage protection circuits.
On-board integrated power isolation can provide stable isolation voltage, and no additional power supply is required for the isolation terminal.
On-board integrated digital isolation can perform signal isolation, featuring high reliability, strong anti-interference capability and low power consumption.
On-board TVS (Transient Voltage Suppressor) can effectively suppress surge voltage and transient peak voltage in the circuit, providing lightning and electrostatic protection.
On-board protection diodes can ensure stable output of current and voltage, prevent overcurrent and overvoltage, and improve anti-impact capability.
On-board terminal power supply interface supports 3.3V ~ 5V DC voltage range for power supply.
Industrial rail-type ABS environmentally friendly shell, small in size, easy to install and high in cost performance.
