You must install the 1734-IB4 onto a 1734-TB or 1734-TBS terminal base unit. The module is keyed to prevent incorrect installation into a base wired for different voltage levels.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I replace this module while the system is running?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe POINT I\/O system supports RIUP (Removal and Insertion Under Power). You can swap the 1734-IB4 while the rest of the rack remains operational, provided you follow standard safety protocols to prevent accidental machine movement during the swap.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs there an internal fuse for the inputs?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe 1734-IB4 relies on the field power distribution to be protected.
