Overview
The Allen-Bradley 1769-IF8 is a Compact I/O analog input module with eight (8) input channels. It connects directly to field devices that send 0–21 mA or ±10V DC analog signals, ensuring precise data acquisition in automation systems. Moreover, it works seamlessly with the 1769 CompactLogix chassis or MicroLogix 1500 controller, making it a reliable solution for industrial control applications.
