The Allen-Bradley 1756-OB16I is a ControlLogix DC digital output module with sixteen (16) independent isolation points. It has no internals, but can use external IFM to protect the output. The recommended fuse type for this module is 5x20mm 4A fast fuse, part number SOC Part number MQ2-4A. For the 1756-OB16I module, the compatible Remote Terminal (RTB) is 1756-TBCH 1756-TBS6H, both of which have 36 pins. RTB is required to provide the signal termination point.

The output channel of the module has a configurable safe state position, and the mode of the controller changes to program and controller failure.

The module also has the following communication format output data, listen only output data, rack optimization, listen only rack optimization, and timed output data. It also allows you to click to select a state in Fault or Program, with Keep Last State, On, or Off as available options for each option, and both are set by default.

It is a 12/24V DC feed/pull current output module with an operating voltage range of 10 to 30V DC. Its backplane current is 350 mA at 5.1V, 2.5 mA at 24V, and the total backplane power is 1.8 W. Its maximum current per point is 2 A at 30 degrees Celsius and 1 A at 60 degrees Celsius (linear derating), while the maximum current per module is 8 A at 30 degrees Celsius and 4 A at 60 degrees Celsius (linear derating). Each point of the surge current can be repeated every 2 seconds at 4 A, 10 ms per point. It also has A minimum load current of 1 mA per point, a maximum on-state capacity drop of 1.2V DC and 2 A, and a maximum off state leakage current of 0.5 mA per point.

The 1756-OB16I module has also been routinely tested for 2 seconds at 1350V AC. It has an output to backplane continuous isolation voltage of 250V and an output to output continuous isolation voltage of 125V. It also has a maximum output delay time of 1 ms from off to on and 2 ms from on to off. The 1756-OB16I module has a power consumption of 3.6W at 60 degrees Celsius (maximum), and its thermal dissipation is 12.28 BTU/hr. It has an operating temperature range of 0 to 60 degrees Celsius and a non-operating temperature range of -40 to 85 degrees Celsius.

The Allen-Bradley 1756-OB16I is a 1756 ControlLogix discrete output module that supports both feed and pull current configurations and operates in the 12/24VDC voltage category. This output module is a single-slot module installed directly into the 1756 chassis.
