Allen-Bradley 1756-0B1 6D is a ControlLogix DC diagnostic output module. It has 16 diagnostic inputs, each group of 8 points fused on the basis of each score. You can install it in any available slot in a Controllogix-compatible chassis. However, a 36-bit detachable wiring box housing (RTB) is required for this purpose. The RTB can be TBCH of 1756 or TBS6H of 1756. Before installing a module with RTB, ensure that the chassis and power supply are installed and grounded.
The 1756-0B1 6D module shares the following characteristics with other output modules: output data echo, multiple output point density, configurable point level output states, electronic fusing, and isolated and non-isolated output modules. It also allows you to configure various functions of the module, especially no-load detection, output verification detection, output state in fault mode, output state in program mode, transition from program state to fault state, and diagnostic latches.
The short stroke diagnostic function of the 1756-0B1 6D module is 8 amps at 180 ms (minimum) and 10 amps at 120 ms (minimum). The no-load function is only used for off status detection, and the output verification is only used for on-status detection. The pulse test has a user-configurable maximum pulse width. The module also allows you to configure the fault state of each point and the program mode state of each point, where the default is set to “off” and the other options are “On” and “Hold Last” This output module has an operating voltage range of 19.2 to 30 volts DC and a 24 volt DC supply voltage category. It also has A minimum load current of 3 mA per point, a maximum off-state leakage current of 1 mA per point and a DC of 1.2V (with a maximum on-voltage drop of 2 A). The backplane current is 140 mA at 24V DC, 250 mA at 5.1V DC, and the total backplane power is 4.64W. Its linear derated output current ratings are up to 2 A at 30 degrees Celsius (80 degrees Fahrenheit), 1 A per point at 60 degrees Celsius (140 degrees Fahrenheit), and 8 A per module at 30 degrees Celsius and 4A at 60 degrees Celsius. The surge current at each point 1756-0B1 6D is 4A for each 10 ms module and can be repeated – times per second. The isolation voltage between the group and the user and the system was tested for 1 second at 2546V, with a maximum continuous AC voltage of 250V for both.
It has a nominal output delay time of 55s, a maximum of 1 ms from off to on, a nominal value of 630 s, and a maximum of 5 ms from on to off. Operating temperatures range from 0 to 60 degrees Celsius (32 to 140 degrees Fahrenheit) and storage temperatures from -40 to 85 degrees Celsius (40 to 185 degrees Fahrenheit).
