The Allen-Bradley 1769-ASCII module is designed for seamless integration with both CompactLogix and MicroLogix 1500 systems, enabling effective communication with devices supporting the ASCII protocol, such as barcode readers commonly used in automation applications. It features two independent, isolated ASCII ports configurable for RS232/RS422 (Port 1) and RS485 (Port 2), supporting simultaneous operations with different device sets, while a compact design facilitates connectivity without the need for an external power supply. Optimized for industrial environments, the 1769-ASCII operates efficiently within a temperature range of 0 to 60 degrees Celsius, withstands substantial shock and vibration, and provides robust electrical specifications to ensure reliable performance in demanding conditions.
