Information About 1756-OB16D
The Allen-Bradley 1756-OB16D is a ControlLogix DC diagnostic output module. It has 16 diagnostic outputs available, with 8 points per group, and has been fused electronically on a per-point basis. You can install it in any available slot in a compatible ControlLogix chassis. However, a 36-position removable terminal block housing (RTB) is required for this. The RTB can either be the 1756-TBCH or the 1756-TBS6H. It is important to install and ground the chassis and power supply before installing the module with the RTB.
This 1756-OB16D module has the following features in common with other output modules: output data echo, multiple output point densities, configurable point-level output states, electronic fusing, and isolated and non-isolated varieties of output modules. It also allows you to configure various features of the module, particularly a no-load detection, output verify detection, output state in Fault mode, output state in Program mode, transition from Program state to Fault state, and diagnostic latching.
The short trip diagnostic function of the 1756-OB16D module is 8 A for 180 ms (minimum) and 10 A for 120 ms (minimum). The no-load function is only for off-state detection and the output verification is only for on-state detection. The pulse test has a user-configurable maximum pulse width. The module also allows you to configure Fault states per point and state in Program mode per point, where 'Off' is set by default and other options are 'On' and 'Hold Last State'.
This output module possesses an operational voltage range of 19.2 to 30V DC and a 24V DC source voltage category. It also has a 3 mA per point minimum load current, a 1 mA per point maximum off-state leakage current, and a 1.2V DC at 2 A maximum on-state voltage drop. Its backplane current is 140 mA at 24V DC and 250 mA at 5.1V DC and comes with a total backplane power of 4.64 W. Its linear derating output current rating is 2 A maximum at 30 Degrees Celsius (80 Degrees Fahrenheit) and 1 A maximum at 60 Degrees Celsius (140 Degrees Fahrenheit) for per-point and the rating is 8 A maximum at 30 Degrees Celsius and 4 A maximum at 60 Degrees Celsius for per-module. The surge current per point of the 1756-OB16D module is 4 A for 10 ms each, which is repeatable for every second. Its isolation voltage from group-to-group and user-to-system have been tested at 2546V for 1 s and both have a 250V AC maximum continuous voltage.
