<h2>Overview</h2>
<p>The <strong>Opto 22 OAC5Q</strong> is a 4-channel AC output module designed for high-density I/O control in industrial automation systems. This Quad Pak module switches AC loads between 12–280 VAC while operating on 5 VDC logic control. Each module integrates four single-channel AC output circuits into a compact package, allowing flexible configuration as two independently paired channels with shared common connections.</p>
<h2>Key Features</h2>
<ul>
<li><strong>4-Channel AC Output:</strong> Switches AC loads from 12–280 VAC with high voltage range flexibility</li>
<li><strong>4000V Optical Isolation:</strong> Transient isolation between field devices and control logic protects system integrity</li>
<li><strong>Zero Voltage Turn-On:</strong> All AC outputs feature synchronized switching at AC zero-crossing for EMI reduction</li>
<li><strong>Quad Pak I/O Form Factor:</strong> Mounts exclusively in Quad Pak high-density racks, not compatible with single-channel systems</li>
<li><strong>Flexible Configuration:</strong> Each module divisible into two independently paired channels with shared common connections</li>
</ul>
