Hello, I hope you are having a great day! I have some inquiries regarding the connection of the "negative channel" and "com" of the analog input module 1762-IF2OF2. 1. Do I need to connect the "COM" to the negative DC power? 2. Can I use a jumper for all the negative connections? 3. Is my expansion module slot arrangement correct, or should there be a preferred slot positioning based on the module (such as which module should be placed first and last)? Please refer to the attached wiring diagram for further clarification and advice on any potential issues. Your assistance is greatly appreciated. Thank you.
1. Should the negative DC power be connected to the "COM" terminal? Yes, it is important to make this connection for proper functionality. 2. Is it safe to connect all the negative terminals with a jumper wire? You may want to verify with a multimeter, but usually, these connections are already made within the module itself. 3. Is the arrangement of my expansion module slots correct, or is there a recommended positioning for specific modules? It looks good to me, but you may want to consider the ideal order for the modules. Please refer to the wiring diagram provided in the attachment and let me know if you have any concerns or questions. Your drawing is well-detailed. Also, double-check the settings of your dip switches for the IF2OF2. Make sure they are set to either V or C depending on the specific application.

Hey there! To answer your questions: 1. Yes, you may want to connect the “COM” to the negative DC power, because it acts as a common reference point for all the channels. 2. A single jumper can be used for all the negative connections, provided all the channels are working within the same power range. But ensure you verify it first. 3. Regarding the module slot arrangement, yes, it can make a difference depending on the communication speed, the type of modules and their power requirement. Check the manufacturer's guidelines for the specific module for a proper arrangement. Remember each system and device can have unique circumstances, so always consider them while designing. Hope this helps!
Hi there! Great questions! Yes, you typically connect the COM terminal to the negative DC power to ensure proper signal reference for your analog input module. Using a jumper for the negative connections is a practical approach as long as it adheres to the current ratings and specifications of your setup. As for the slot arrangement, it's usually best to place your power supply modules first and then follow with the input/output modules to minimize noise, but checking your specific system's guidelines is a good idea. If you share your wiring diagram, I might be able to give more tailored advice. Hope that helps!
