<div class="PlainText">One other thought for driving the heaters might be an LED driver for dimmable lights. For example:<br>
<a href="https://www.amazon.com/Constant-120-277VAC-Channels-Dimmable-Aluminum/dp/B0B8WN97CC/ref=sr_1_8?crid=3UPVJS4F25U05&keywords=0-10v%2Bdimmable%2Bled%2Bdrivers&qid=1681753510&sprefix=0-10v%2Bdimmable%2Bled%2Bdrivers%2Caps%2C64&sr=8-8&th=1">https://www.amazon.com/Constant-120-277VAC-Channels-Dimmable-Aluminum/dp/B0B8WN97CC/ref=sr_1_8?crid=3UPVJS4F25U05&keywords=0-10v%2Bdimmable%2Bled%2Bdrivers&qid=1681753510&sprefix=0-10v%2Bdimmable%2Bled%2Bdrivers%2Caps%2C64&sr=8-8&th=1</a><br>
<br>
You can search Amazon for<br>
0-10v dimmable led drivers<br>
<br>
Maybe this would be more compatible with the cRIO.<br>
