Description
TTL to RS485 Electrical Isolation Module DIN Rail Serial Converter Stable Communication 600W Lightning Protection
Features:
1. Compatible with the TTL/RS485 standard, it can convert TTL signals into differential RS485 signals, half-duplex communication.
2. Compatible with 3.3V ~ 5V TTL signal levels, power supply connector has a reverse polarity and overvoltage protection circuit.
3. The integrated onboard power supply isolation can provide a stable isolation voltage, and the isolation connector requires no additional power supply.
4. Integrated digital isolation on board, which can perform signal isolation with high reliability, strong interference suppression and low power consumption.
5. The integrated TVS (Transitute Voltage Suppression Pipe) can effectively suppress surge voltages and temporary voltage spikes in the circuit and prevent lightning strikes and static electricity.
6. The integrated self-recovery fuse and protection diode ensure stable current and voltage output, prevent overcurrent and overvoltage, and improve shock resistance.
7. On-mounted RS485 output terminal with 120Ω resistor, switchable and enable, easy operation
8. Industrial rail ABS environmental protection shell, small size, easy to install and high cost performance.
