SPECIFICATIONS

Product Features:

Compatible with TTL/RS485 standards, converts TTL signals into differential RS485 signals, supporting half-duplex communication.

Compatible with 3.3V–5V TTL signal levels, featuring reverse polarity protection and overvoltage protection on the power supply side.

Onboard integrated power isolation, providing stable isolated voltage without requiring additional power on the isolated side.

Onboard integrated digital isolation for signal isolation, offering high reliability, strong anti-interference, and low power consumption.

Onboard TVS (Transient Voltage Suppressor) to effectively suppress surge voltage and transient spikes, providing lightning and electrostatic protection.

Onboard self-recovery fuse and protection diode to ensure stable current and voltage output, protecting against overcurrent and overvoltage, and improving impact resistance.

Onboard 120Ω RS485 terminal resistor, switchable for easy operation.

Industrial rail-mounted ABS eco-friendly housing, compact size, easy installation, and high cost-performance.
