<h2>Overview</h2>
<p>The <strong>Allen-Bradley 1769-IF4I</strong> is a CompactLogix four-channel isolated analog input module designed to acquire accurate current and voltage signals from field devices. <cite index=”1-1,1-2″>This module is a CompactLogix four-point analog input module that is isolated and handles both current and voltage with 16-bit resolution.</cite> It digitizes analog data for direct use by CompactLogix and MicroLogix controllers, eliminating the need for external signal conditioning in many applications.</p>
