You will still need an opto isolator.<div id="yiv0252341171yui_3_16_0_ym19_1_1483893213641_4672"><br clear="none"></div><div id="yiv0252341171yui_3_16_0_ym19_1_1483893213641_4649">~Carl<br clear="none"></div></div></div></div></div> </div></div><div class="yiv0252341171yqt8182019916" id="yiv0252341171yqtfd63002"> </div></div><div class="yiv0252341171yqt8182019916" id="yiv0252341171yqtfd38999"> </div></div></div></div></div><br><br></div> </div> </div> </div></div></body></html>
