local expansion bus interface to guarantee deterministic register updates without increasing PLC processor scan-time latency.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eI\/O Density Scaling\u003c\/strong\u003e: Integrates additional analog input channels directly into the base controller memory map, providing modular expansion without requiring external remote communication protocols.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can the 1745-E107 expansion unit be hot-swapped while the system is under power?\u003c\/p\u003e\n\u003cp\u003eA: No. Connecting or removing the interconnect cable while power is active can corrupt backplane bus communication and trip primary CPU hardware fault routines.\u003c\/p\u003e\n\u003cp\u003eQ: How is logic and bus communication power delivered to the 1745-E107 unit?\u003c\/p\u003e\n\u003cp\u003eA: Power is supplied through the dedicated bus interconnect cable connected to the primary SLC 100\/150 processor base unit or preceding expansion chassis.\u003c\/p\u003e\n\u003cp\u003eQ: Is a dedicated communication interface card required to interface the 1745-E107 with an SLC 150 CPU?\u003c\/p\u003e\n\u003cp\u003eA: No. The unit connects directly to the local backplane expansion socket of the SLC 100 or SLC 150 controller via a standard interconnect cable.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eIsolate all primary AC\/DC power sources from the main processor unit and attached expansion chassis prior to mounting or connecting the 1745-E107 module.\u003c\/li\u003e\n\u003cli\u003eSecure the expansion unit frame tightly to the metal enclosure mounting panel to maintain proper frame earth grounding and mechanical stability.\u003c\/li\u003e\n\u003cli\u003eUtilize shielded twisted-pair cabling for all analog input signal lines, ensuring shield termination occurs at a single grounded point to prevent ground loop interference.\u003c\/li\u003e\n\u003cli\u003eMaintain a 2.0 in (50.8 mm) minimum operational clearance above and below the chassis assembly to allow proper thermal convective airflow inside the cabinet.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Allen-Bradley","offers":[{"title":"Default
