Features and Benefits

● 2 Serial Ports with RS232/422/485 Support
Each port supports RS232, RS422, and RS485 interfaces (selectable via DIP switch), making on-site setup fast and flexible.

● Auto RS-485 Data Flow Control
Automatically manages RS-485 data direction without handshake signals.

● Auto Baud Rate Detection
Automatically detects the baud rate of serial signals.

● Supports 0–256 Kbps Asynchronous Data
Transmits serial data with adaptive baud rates from 0 to 256 Kbps.

● 6kV Surge Protection for Serial Ports
Meets IEC61000-4-5 (10/700μs) standard: 6kV protection in both differential and common modes (2Ω impedance).

● Dual Wide-Range Power Input

Supports DC 9–55V or AC 7–50V power supply.
Auto polarity detection—no need to worry about positive or negative during installation.
Features internal isolation, redundant dual power inputs, and reverse polarity protection.

● Wide-Range AC/DC Power Input
Supports AC 85–265V or DC 110–300V wide-range input.

● Flexible Mounting Options
Supports DIN 35mm rail or wall mounting.
