Connected via an interconnecting ribbon cable, it provides control engineers with an integrated hardware solution to expand input and output points without adding another standalone processor.\u003c\/p\u003e\n\u003ch3\u003eField I\/O Architecture and Electrical Isolation\u003c\/h3\u003e\n\u003cp\u003eThe unit features 10 discrete inputs requiring an 8 mA nominal input current, along with 6 discrete outputs wired via screw-type terminals that accept 14 to 24 AWG conductors. To shield sensitive control logic from field-side voltage transients, the inputs incorporate 1,500 V electrical-optical isolation. Signal conditioning includes an input filter time delay of 18 to 25 ms to mitigate contact bounce, while safety limits specify a maximum OFF-state voltage of 50 V and a maximum OFF-state leakage current of 2 mA.\u003c\/p\u003e\n\u003ch3\u003eDiagnostic Monitoring and Power Specifications\u003c\/h3\u003e\n\u003cp\u003eReal-time status monitoring is provided by front-panel indicators, consisting of 6 green LEDs for input state verification and 10 red LEDs for output status tracking. The internal power supply operates across dual selectable line voltage windows of 85 to 132 VAC and 170 to 265 VAC at standard 50\/60 Hz system frequencies.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003e1745-E102\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eAllen-Bradley\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eProgrammable Controller Expansion Unit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Voltage Range\u003c\/td\u003e\n\u003ctd\u003e85–132 VAC \/ 170–265 VAC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSystem Frequency\u003c\/td\u003e\n\u003ctd\u003e50\/60 Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Inputs\u003c\/td\u003e\n\u003ctd\u003e10 input terminals\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRated Input Current\u003c\/td\u003e\n\u003ctd\u003e8 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Outputs\u003c\/td\u003e\n\u003ctd\u003e6 output terminals\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Filter Time Delay\u003c\/td\u003e\n\u003ctd\u003e18–25 ms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIsolation\u003c\/td\u003e\n\u003ctd\u003e1,500 V electrical-optical isolation (inputs to control logic)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax OFF State Voltage\u003c\/td\u003e\n\u003ctd\u003e50 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax OFF State Leakage Current\u003c\/td\u003e\n\u003ctd\u003e2 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLocal Signalling\u003c\/td\u003e\n\u003ctd\u003e6 green LEDs (inputs), 10 red LEDs (outputs)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSystem Interconnect\u003c\/td\u003e\n\u003ctd\u003eRibbon cable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTermination Method\u003c\/td\u003e\n\u003ctd\u003eScrew-type terminals\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWire Size\u003c\/td\u003e\n\u003ctd\u003e14–24 AWG\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e1.81 kg (4.00 lbs)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003cp\u003eFrequently Asked Questions\u003c\/p\u003e\n\u003cp\u003eQ: How does the 1745-E102 expansion unit communicate with the main controller?
