Part of the ControlLogix series, this DigitalDC Input module accepts a 10-30VDC signal range with a nominal 24VDC, making it ideal for interfacing pushbuttons, switches, and auxiliary contacts. The Allen-Bradley 1756-IB16I mounts in any 1756 chassis (except the leftmost slot reserved for processors) and supports local or remote I\/O architectures.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003cp\u003eThe Allen-Bradley 1756-IB16I delivers precise performance with the following key parameters from the product database:\u003c\/p\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Voltage Range\u003c\/td\u003e\n\u003ctd\u003e10-30 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Inputs\u003c\/td\u003e\n\u003ctd\u003e16 individually isolated\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eON-State Current (min\/max)\u003c\/td\u003e\n\u003ctd\u003e2 mA @ 10V DC \/ 10 mA @ 30V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCyclic Update Time\u003c\/td\u003e\n\u003ctd\u003e200 µs to 750 ms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSignal Delay, OFF to ON\u003c\/td\u003e\n\u003ctd\u003eHardware delay 1 ms max + filter time (0, 1, or 2 ms)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSignal Delay, ON to OFF\u003c\/td\u003e\n\u003ctd\u003eHardware delay 4 ms max + filter time (0, 1, 2, 9, or 18 ms)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBackplane Current (5.1VDC)\u003c\/td\u003e\n\u003ctd\u003e100 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBackplane Current (24VDC)\u003c\/td\u003e\n\u003ctd\u003e3 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTotal Backplane Power\u003c\/td\u003e\n\u003ctd\u003e0.58 W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Dissipation (Max)\u003c\/td\u003e\n\u003ctd\u003e5 W at 60°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRemovable Terminal Blocks\u003c\/td\u003e\n\u003ctd\u003e1756-TBCH, 1756-TBS6H\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003cp\u003eThese specs ensure stable performance even in demanding industrial environments. The Allen-Bradley 1756-IB16I's isolation eliminates ground loops, reducing maintenance and downtime.\u003c\/p\u003e\u003ch2\u003eIndustry Applications\u003c\/h2\u003e\u003cp\u003eIn manufacturing lines, the Allen-Bradley 1756-IB16I connects limit switches and proximity sensors to the control system. Its 16 isolated channels mean one faulty sensor does not affect others — reducing troubleshooting time. In material handling, it monitors conveyor status with fast cyclic updates as low as 200 µs. For asset-intensive industries, the Allen-Bradley 1756-IB16I provides long-term reliability, lowering total cost of ownership.\u003c\/p\u003e\u003ch2\u003eCompatibility \u0026amp; Integration\u003c\/h2\u003e\u003cp\u003eThe Allen-Bradley 1756-IB16I integrates seamlessly with any ControlLogix chassis. Use the 1756-TBCH or 1756-TBS6H removable terminal block for wiring. The module works in local, remote, or distributed I\/O configurations. No special software is needed — standard ControlLogix programming tools configure the filter times and input settings.\u003c\/p\u003e\u003ch2\u003eSelection Guide \u0026amp; Purchasing Advice\u003c\/h2\u003e\u003cp\u003eBefore buying the Allen-Bradley 1756-IB16I, verify your chassis has an available slot and that you have the correct RTB (1756-TBCH or 1756-TBS6H). Check that your backplane can supply 5.1VDC at 100 mA plus 24VDC at 3 mA. UBEST Automation stocks genuine Allen-Bradley 1756-IB16I modules and offers fast shipping.
