The Allen-Bradley 1746-ITB16 is a high-performance SLC500 fast response discrete input module, designed for integration within SLC 500 chassis. Featuring sixteen input channels, it efficiently handles high-speed, rapid-switching signals, with capabilities that include reading pulse frequencies up to 1 kHz with SLC 5/03 or 5/04 processors, or up to 2 kHz when interfacing with a gray code encoder. Operating at 10-30V DC with a nominal 24V DC, it demands 0.085 A backplane current and accommodates sink wiring configurations, providing precise readouts with minimal signal delays of 0.43 ms for OFF to ON and 0.5 ms for ON to OFF transitions. Notably, this module mandates installation with power removed, occupies a single chassis slot, and includes features such as filter circuitry, optical coupling for noise reduction, and removable terminal blocks for seamless replacement. It supports Ladder Logic programming, ensuring efficient data handling and diagnostic ease with LED status indicators, suited for demanding environments at temperatures between 32 and 140°F and relative humidity of 5-95%.
