FAQ for 1756-IA16K
The Allen-Bradley 1756-IA16K is a part of ControlLogix Digital AC Input Module with 16 (8 points/group) individually-isolated inputs. This module gives off a maximum of 5.8 W at 60 °C of power dissipation and 18.41 BTU/hr of thermal dissipation. The 1756-IA16K uses the 1756-TBNH or the 1756-TBSH as a removable terminal block housing and a user-defined mechanical type of RTB keying. With an open-style type of enclosure, it operates within a temperature range of 0 - 60 °C and has the conformal coating option that covers the assembly with a seal that protects the module from humidity and contaminants (“K” indication).
The 1756-IA16K exhibits a maximum off-state voltage of 20V and maximum off-state current of 2.5 mA. With a maximum inrush current of 250 mA, the 1756-IA16K has a maximum input impedance of 10.15 kï— at 132V AC, 60 Hz and caters a cyclic update time from 200 ïs up to 750 ms. Moreover, this ControlLogix Digital AC Input Module has a software configurable type of change of state, ±200 μs time stamp of inputs, and 125V (continuous) isolation voltage. This 120V AC ControlLogix isolated input module operates from 74V AC up to 132V AC and 47- 63 Hz frequency range. The 1756-IA16K’s nominal input voltage is 120V AC and it has a total backplane power of 0.58 W. It draws current at 5.1V of 100 mA and 2 mA at 24V. Moreover, the 1756-IA16K caters an off-to-on maximum hardware delay time of 10 ms and an on-to-off maximum hardware delay time of 8 ms.
