FAQ for 1756-IB16K
The 1756-IB16K is a part of Allen-Bradley ControlLogix DC Input Module series with 16 (8 points/group) individually-isolated inputs. Moreover, this 24V DC ControlLogix Input Module has an electronic software-configurable type of module keying, ±200 μs time stamp of inputs and 250V (continuous) isolation voltage. The 1756-IB16K uses the 1756-TBNH or the 1756-TBSH as a removable terminal block housing and a user-defined mechanical type of RTB keying. This module gives off a maximum of 5.1 W at 60 °C of power dissipation, 17.39 BTU/hr of thermal dissipation, and exhibits a maximum inrush current of 250 mA. This 24V DC ControlLogix input module operates from 10-31.2V DC and belongs to a 12-24V DC sink voltage category. The 1756-IB16K has a nominal input voltage of 24V DC and has a total backplane power of 0.56 W. It draws current at 5.1V of 100 mA and 2 mA at 24V. Moreover, the 1756-IB16K caters an off-to-on nominal hardware delay time of 290 ms and an on-to-off nominal hardware delay time of 700 ms.
With an open-style type of enclosure, the 1756-IB16K operates within a temperature range of 0 °C - 60 °C and has the conformal coating option that covers the assembly with a protective seal against humidity and contaminants (it has the “K” indication). The 1756-IB16K utilizes a maximum off-state voltage of 5V and maximum off-state current of 1.5 mA. With a minimum and maximum on-state current of 2 mA at 10V DC and 10 mA at 31.2V DC respectively, the 1756-IB16K has a maximum input impedance of 3.12 kW at 31.2V DC and caters a cyclic update time from 200 ms up to 750 ms.
