Operating at low-voltage TTL logic levels with a nominal voltage rating of 5 VDC (4.5 to 5.5 VDC operating range) and sourcing input circuit topology, this module interfaces low-voltage discrete field devices, sensors, and electronic circuits directly with the host SLC 500 processor backplane.\u003c\/p\u003e\n\u003ch3\u003eFunctional Operation and System Compatibility\u003c\/h3\u003e\n\u003cp\u003eDesigned for installation into any open slot of a 1746 chassis, the \u003cstrong\u003e1746-IG16\u003c\/strong\u003e detects discrete sourcing signal states from 5 VDC TTL electronic field devices. The module provides optical isolation to protect internal backplane logic from field-side noise and voltage transients while continually updating input image tables for execution by the PLC processor.\u003c\/p\u003e\n\u003cp\u003eWiring and Module Safety Notice\u003c\/p\u003e\n\u003cp\u003eEnsure chassis backplane power and external signal power are turned off before inserting, removing, or wiring the module. Applying voltages outside the 4.5 to 5.5 VDC range will cause permanent damage to module inputs.\u003c\/p\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\u003e1746-IG16\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 Line\u003c\/td\u003e\n\u003ctd\u003eSLC 500\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDevice Type\u003c\/td\u003e\n\u003ctd\u003eDigital Input Module\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInputs\u003c\/td\u003e\n\u003ctd\u003e16 points\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNominal Voltage\u003c\/td\u003e\n\u003ctd\u003e5 VDC TTL\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Voltage Range\u003c\/td\u003e\n\u003ctd\u003e4.5 to 5.5 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCircuit Topology\u003c\/td\u003e\n\u003ctd\u003eSourcing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSignal Type\u003c\/td\u003e\n\u003ctd\u003eDiscrete \/ Digital\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting Location\u003c\/td\u003e\n\u003ctd\u003e1746 SLC Chassis Slot\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.23 kg (0.51 lbs)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eRemove power from the SLC 500 rack and associated 5 VDC field power sources prior to installation.\u003c\/li\u003e\n\u003cli\u003eAlign the circuit board of the \u003cstrong\u003e1746-IG16\u003c\/strong\u003e with the chassis guide rails in the designated 1746 slot.\u003c\/li\u003e\n\u003cli\u003eSlide the module into the slot until the top and bottom retaining latches lock firmly in position.\u003c\/li\u003e\n\u003cli\u003eWire the 5 VDC TTL sourcing input signals to the corresponding terminals on the removable terminal block (RTB) according to system schematic guidelines.\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp\u003eFrequently Asked Questions\u003c\/p\u003e\n\u003cp\u003eQ: What operating voltage range does the 1746-IG16 support?
