<h2>Introducing the SPA-0140 SynLink Smart IO Hub</h2>
<p>The SPA-0140 Smart Io Hub is an accessory for SynLink Smart PDUs that provide next-generation automation and environmental sensing solutions.<span data-mce-fragment="1"> </span>With its advanced digital input sensors ranging from motion detectors to air flow sensors, potential threats are identified and mitigated swiftly.</p>
<p><span><meta charset="utf-8">In addition to sensing, its ability to control a variety of output relay devices, such as actuators and sprinklers, brings a degree of automation that can drastically reduce operational costs. Take, for example, a water leakage in your lab; with SynLink Smart IO Hub solutions, water sensors can detect presence of water and solenoid/ball valves can spring into action to prevent equipment damage, potentially saving thousands in repairs and replacements.</span></p>
<h3></h3>
<h3>Application: <span style="color: #ff2a00;" data-mce-style="color: #ff2a00;">Set up water detection sensors and automate shutoff valves to prevent equipment damage, repairs, and replacements.</span>

<h4>4. Name your leak detection sensor and solenoid/ball valve</h4>
<p>Naming the leak detection sensor and solenoid ball valve will make managing events, actions, and general usage more intuitive.</p>
<p><img src="https://cdn.shopify.com/s/files/1/0496/7835/2545/files/7_8dffaf2b-fc9f-4d04-9750-c52edc68aa6d_600x600.png?v=1694204165" alt=""></p>

<h4></h4>
<h4>5. Create an event action to shut off valve</h4>
<p>Event action is an action the PDU takes when triggered by a particular event trigger. We will create an action that will make the attached valve to shut off and stop the flow of liquid.</p>
<div style="text-align: start;" data-mce-style="text-align: start;"><img style="float: none;" alt="" src="https://cdn.shopify.com/s/files/1/0496/7835/2545/files/9_607d0e70-65c1-4c7f-9121-36d9065edcf4_1024x1024.png?v=1694204546" data-mce-style="float: none;"></div>
<div style="text-align: start;" data-mce-style="text-align: start;"><img style="float: none;" alt="" src="https://cdn.shopify.com/s/files/1/0496/7835/2545/files/Screenshot_2023-09-08_at_1.25.22_PM_1024x1024.png?v=1694204758" data-mce-style="float: none;"></div>
<p>Select the appropriate <strong>Sensor Port</strong>, the output relay that is labeled for the attached valve, and the state of <strong>OPEN</strong>. The example ball valve will cut off the flow of water when provided voltage is cut.</p>
<p> </p>
<h4>6. <meta charset="utf-8">Create a trigger to detect leaks with water sensor</h4>
<p>Event triggers are always being monitored for conditions that warrant an action. The following trigger will monitor the leak detection sensor and will shut off the valve automatically when triggered.</p>
<p> </p>
<div style="text-align: start;" data-mce-style="text-align: start;"><img style="float: none;" alt="" src="https://cdn.shopify.com/s/files/1/0496/7835/2545/files/10_25269277-3b00-4e59-b489-7f9c2c184159_1024x1024.png?v=1694204998" data-mce-style="float: none;"></div>
<div style="text-align: start;" data-mce-style="text-align: start;"><img style="float: none;" alt="" src="https://cdn.shopify.com/s/files/1/0496/7835/2545/files/Screenshot_2023-09-08_at_1.39.28_PM_1024x1024.png?v=1694205581" data-mce-style="float: none;"></div>
<p><br><strong></strong></p>
<p>Be sure to select the <strong>Digital Input State High </strong>event type. Select the appropriate <strong>Sensor Port</strong>, the labeled leak detection sensor, and a max time over threshold. With this configuration, if the leak detector is wet, the digital input will change from <strong>LOW</strong> (dry) to <strong>HIGH</strong> (wet), and if it stays wet for 5 seconds: the action "Shut off Valve #1" will trigger.</p>
<p> </p>
<h4>7. Review all Smart IO Hub triggers and actions</h4>
<p>On the System -&gt; Sensors page you will be able to see all events and actions you have created.  <img src="https://cdn.shopify.com/s/files/1/0496/7835/2545/files/Screenshot_2023-09-08_at_1.49.42_PM_1024x1024.png?v=1694206195" alt="" data-mce-fragment="1" data-mce-src="https://cdn.shopify.com/s/files/1/0496/7835/2545/files/Screenshot_2023-09-08_at_1.49.42_PM_1024x1024.png?v=1694206195"></p>
<p>History of all event triggers can be found under Logging -&gt; Event Log</p>
<p><img alt="" src="https://cdn.shopify.com/s/files/1/0496/7835/2545/files/Screenshot_2023-09-08_at_1.50.39_PM_600x600.png?v=1694206266"></p>
<p><br><strong>8. Shut off all ball valves with front panel user switch for emergencies.</strong></p>
<p>Switch the following user switch to set all output relays to OPEN. In this setup, all attached ball valves will lose voltage, and the valves will shut off. OPEN output relay = CLOSED valve.</p>
<p><img src="https://cdn.shopify.com/s/files/1/0496/7835/2545/files/11_a8a5a65b-9181-4dd3-b608-9280f18eab70_600x600.png?v=1694206512" alt="" data-mce-fragment="1" data-mce-src="https://cdn.shopify.com/s/files/1/0496/7835/2545/files/11_a8a5a65b-9181-4dd3-b608-9280f18eab70_600x600.png?v=1694206512"> </p>
