This robust industrial module features eight switch-selectable inputs configured to support either current sourcing or current sinking applications, accommodating both high-true and low-true logic structures. Ideal for complex automation tasks, the 1771-IQ offers versatile filtering options with switch-selectable input delays, allowing engineers to switch between normal operational modes and fast response configurations depending on specific application demands.\u003c\/p\u003e\n\u003cp\u003eEngineered for reliable performance in demanding factory floor environments, the module handles a customer supply voltage range of 5VDC to 30VDC. Configuration switches located on the hardware must be set prior to installation in either a Series A or Series B 1771 I\/O chassis backplane. Its flexible design simplifies integration into legacy control architectures requiring adaptable discrete signal processing.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eEight switch-selectable inputs supporting current sourcing or current sinking devices\u003c\/li\u003e\n  \u003cli\u003eConfigurable for high-true or low-true logic operation\u003c\/li\u003e\n  \u003cli\u003eSelectable input signal delay times: normal mode (12ms nominal) or fast mode (under 1ms)\u003c\/li\u003e\n  \u003cli\u003eCompatible with Series A and Series B 1771 I\/O chassis backplanes\u003c\/li\u003e\n  \u003cli\u003eComprehensive optical isolation rated at 1500VAC rms for enhanced noise immunity\u003c\/li\u003e\n  \u003cli\u003eOn-board hardware configuration switches for logic and delay settings\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eLegacy Allen-Bradley PLC-5 automation and control systems\u003c\/li\u003e\n  \u003cli\u003eDiscrete manufacturing and assembly lines\u003c\/li\u003e\n  \u003cli\u003eProcess control monitoring requiring flexible sinking\/sourcing signal matching\u003c\/li\u003e\n  \u003cli\u003eIndustrial machinery upgrade and maintenance projects\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\n    \u003ctr\u003e\n      \u003cth\u003eParameter\u003c\/th\u003e\n      \u003cth\u003eSpecification\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eManufacturer\u003c\/td\u003e\n      \u003ctd\u003eAllen-Bradley \/ Rockwell Automation\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eExact Model\u003c\/td\u003e\n      \u003ctd\u003e1771-IQ\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eProduct Type\u003c\/td\u003e\n      \u003ctd\u003eDC Selectable Input Module\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eModule Family\u003c\/td\u003e\n      \u003ctd\u003ePLC-5 \/ 1771 Universal I\/O\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eInputs per Module\u003c\/td\u003e\n      \u003ctd\u003e8 (switch-selectable sinking\/sourcing)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCustomer Supply Voltage Range\u003c\/td\u003e\n      \u003ctd\u003e5 to 30 VDC\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eNominal Input Current\u003c\/td\u003e\n      \u003ctd\u003e5mA at 5VDC to 25mA at 30VDC\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eInput Impedance\u003c\/td\u003e\n      \u003ctd\u003e1.2 kOhms nominal\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eInput Signal Delay\u003c\/td\u003e\n      \u003ctd\u003eFast: \u0026lt;1ms;
