The 1756-IA16IK input module is a ControlLogix 120 Volts AC rated isolated input module that is designed and manufactured by Allen-Bradley. This module is one of the most efficient modules because it takes up very little space on 1 digital input. Further advantages of this module with 16 isolated digital inputs are its ability to be replaced without disturbing the wiring to the sensors around it, as well as the ability to work in environments with high humidity and temperature levels, as well as with dangerous gases. The 1756-IA16IK input module has 16 status indicators to show which input is active. The inputs are triggered with an outside generated voltage that can be between 79 and 132 Volts AC (at 47 to 63 Hertz). The cyclic update time for this module is always less than 750 milliseconds but it can be 1000 times less. It provides input-to-input and input-to-backplane 125 Volts AC isolation voltage.
The Allen-Bradley 1756-IA16IK 16-channel DI module has an electronic module keying process that is software configurable. It is fitted to 1 of 2 types of terminal base units which are the 1756-TBCH or the 1756-TBS6H terminal base unit. The declared time delays for this module are 10 milliseconds plus the filtering time that users can set to be 1 or 2 milliseconds for the OFF to ON transitioning process and 8 milliseconds plus the filtering time that users can set to be 9 or 18 milliseconds for ON to OFF transitioning process. The 1756-IA16IK input module consumes 0.71 Watts of backplane power, and it is designed to operate at temperatures between 0 and 60 degrees Celsius. The product is CSA, UL, CE, and EAC certified.
FAQ for 1756-IA16IK
The 1756-IA16IK is a member of Allen-Bradley ControlLogix Digital AC Input Module series with 16 individually-isolated inputs. This 120V AC ControlLogix isolated input module operates on 79V AC up to 132V AC at a 50-60 Hz frequency. The 1756-IA16IK has a nominal input voltage of 120V AC and has a total backplane power of 0.71 W. It draws current at 5.1V of 125 mA and 3 mA at 24V. Moreover, the 1756-IA16IK caters an off-to-on maximum hardware delay time of 10 ms and an on-to-off maximum hardware delay time of 8 ms. This module gives off a maximum of 4.9 W at 60 °C of power dissipation and 16.71 BTU/hr of thermal dissipation.
The 1756-IA16IK 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-IA16IK has a maximum input impedance of 8.8 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. The 1756-IA16IK uses the 1756-TBCH or the 1756-TBS6H 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 32 °F - 140 °F and has the conformal coating option that covers the assembly seals from humidity and contaminants (“K” indication).
