/community-hubs/deltav-community-connect/b/delta-vweblog/posts/update-providing-24vdc-to-field-devicesIn a blog posted late last month I addressed how to provide a 24VDC source of power to a three wire field device. In the past I have used a 24VDC High Side Discrete output to provide&#160; 24VDC to these types of devices. This solution can be&#160; implementeden-USTelligent Community 13https://emersonexchange365.com/community-hubs/deltav-community-connect/b/delta-vweblog/posts/update-providing-24vdc-to-field-devicesTue, 17 Nov 2020 12:52:39 GMTcd40bb2b-3d49-4868-939d-417119b40291:7ac4fac3-6a9e-4c41-bab3-ed4a922e6e13Aidan Fusco0Hello Terry, does this also apply to the IS Marshalling hardware ? I am planning to install an Endress and Hauser flow switch that is sending a DI signal to an IS DI Namur charm. The device also requires field power between 18-30 VDC and I am not clear on where I can supply this power from. I am connecting my digital signal to terminals 3 and 4 on my IS Charm terminal block, terminals 1 and 2 are available for use. Any info would be much appreciated. Thanks, Aidan. <img src="https://emersonexchange365.com/aggbug?PostID=3008&AppID=48&AppType=Weblog&ContentType=0" width="1" height="1">
