Descrption
The Allen-Bradley 1756-OA16I is a single-slot ControlLogix AC output module designed for installation in any 1756 series chassis, including the 1756-A4, 1756-A7, 1756-A10, 1756-A13, and 1756-A17. It can be mounted in a local ControlLogix rack alongside the controller or used in a remote I/O chassis when paired with a 1756 communication adapter.
This module allows individual configuration of fault behavior for each output point. Available fault states include holding the last output state, forcing the output ON, or turning it OFF, with OFF set as the default option. Output behavior during program mode can also be defined using the same selectable states. Although the module does not include internal fusing, it provides electrical isolation rated at 250 volts continuous with basic insulation between outputs and the backplane, as well as between individual outputs.
The module provides an output update schedule time of 16.7 milliseconds and maintains an isolation rating of 250 volts using basic insulation, tested at 1350 volts AC for two seconds between outputs and the backplane. It occupies a single chassis slot and uses user-defined removable terminal block keying. The open-style housing is rated with a T4A temperature code.
Designed for industrial environments, the 1756-OA16I operates within a temperature range of 0 to 60 °C under 5% to 95% non-condensing humidity. It is also rated to withstand operational shock levels of up to 30 G, making it suitable for demanding automation applications.

Common Problem
What payment methods do you accept?
We only accept 100% T/T in advance for your convenience.
How is the 1756-OA16I physically integrated into a ControlLogix system?
The module installs directly into a 1756 ControlLogix chassis or I/O rack. Field wiring is connected via its removable front-facing terminal block, which simplifies installation and maintenance within an industrial control panel.
Does swapping a 1756-OA16I module require reprogramming the Logix controller?
Typically, no. The module supports Rockwell Automation's Electronic Keying feature. If replaced with an identical module type, the ControlLogix controller recognizes it without requiring changes to the Studio 5000 or RSLogix 5000 project, provided the configuration matches.
Can replacing an older 1756-OA16I module enhance system reliability?
Absolutely. Installing a new module eliminates wear and degradation associated with aged internal components, ensuring precise switching, restoring full output current capability, and preventing intermittent failures that disrupt production.
