<h2>Overview</h2>
<p>The <strong>Allen-Bradley 1746-OW16</strong> Series C is a digital relay output module designed for the SLC 500 family of programmable logic controllers. <cite index=”4-1″>This 16-channel relay output module</cite> provides normally open relay contact outputs that switch both AC and DC loads across a wide voltage range. <cite index=”5-11″>As a relay output module from the SLC 500 programmable controllers series</cite>, the 1746-OW16 is ideal for industrial applications requiring isolated switching of external circuits without heavy software overhead.</p>
<h2>Key Features</h2>
<ul>
<li><cite index=”10-2″>16 relay outputs organized in 2 groups of 8 per common</cite></li>
<li><cite index=”5-2″>Operates with AC and DC relay voltage with backplane voltage levels of 5 Volts DC or 24 Volts DC</cite></li>
<li><cite index=”9-9″>Removable terminal block facilitates easy wiring and maintenance</cite></li>
<li><cite index=”10-2″>Isolation voltage of 1500V AC (backplane to output) and 500V DC (between outputs and user power)</cite></li>
<li><cite index=”5-18″>Terminal blocks guarded with barriers to prevent shorting of wiring</cite></li>
<li><cite index=”5-14″>All fixed and modular SLC 500 processors can receive data from the 1746-OW16 module</cite></li>
</ul>
