About 1794-APB
The product code 1794-APB is the product code for a PROFIBUS adapter module from the Bulletin 1794/Series B product line by Allen-Bradley/Rockwell Automation. The module is intended for Allen-Bradley FLEX I/O systems and it works on 24 Volts DC rated power sources. The module is part of a modular I/O system which is, due to its many possible functions, used for a variety of applications across different industries. The FLEX I/O system is constructed from several components that include an I/O module, a terminal base, and a power supply or adapter. The 1794-APB adapter module provides the power for internal logic for a maximum of 8 I/O modules.
The 1794-APB module can be mounted in both vertical and horizontal positions and it uses a standard DIN rail, which is typical for FLEX I/O components. The module has screw holes for optional panel-mounting and slots for the DIN rail, along with a locking tab connector which secures the terminal base onto the rail. The 1794-APB module is a small part with the following dimensions (HxWxD): 87 x 68 x 69 millimeters (3.4 x 2.7 x 2.7 inches). The operating temperature of the module is a maximum of 55 degrees Celsius (131 degrees Fahrenheit). The module comes equipped with diagnostic indicators for the status of the device and the status of the communication link. Every time the module powers up, it performs a self-test for potential errors in operation. The 1794-APB module communicates with a maximum rate of 12 megabits per second and it has a Flexbus output current of 640 milliAmps at 5 Volts DC. The average power consumption of the module is 400 milliAmps.
