If your system uses 120V AC field loops, you must use a dedicated 120V AC input card (such as the 1746-IA16) to ensure proper signal detection.\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eWhat precautions should I take regarding the terminal block common path?\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003eBecause all 16 channels share a single common, you must ensure that all field inputs routed to this module originate from the same electrical phase and voltage source.
