Allen Bradley 1792D-CBFM

As a professional supplier, we guarantee that every Allen Bradley 1792D-CBFM unit you buy is an original, brand-new and genuine product. It is a "frontline commander" in Rockwell Automation's ArmorBlock® series. It is not a delicate module hidden in the control cabinet, but a sturdy "battle fortress" that can be directly installed on machinery and equipment. Its core task is to receive digital instructions from the PLC brain (via the DeviceNet network), and then directly control the AC or DC equipment on site, such as motors, solenoid valves, alarm lights, etc.

The Allen Bradley 1792D-CBFM module is essentially a "solid little box" that can be directly installed on the machine. Its sole function is to receive commands from the PLC in the control cabinet via a network cable (DeviceNet), and then use its 8 small switches (relays) to directly control the large equipment that requires high voltage in the field, such as motors and solenoid valves. The advantage of this is that it separates the PLC from those high-voltage equipment, protecting the PLC's "brain" from being damaged. Moreover, each switch on it has a small light, indicating whether it is on or off, good or bad. It's extremely convenient.

What can our Allen Bradley 1792D-CBFM do?

The Allen Bradley 1792D-CBFM is precisely to address several major drawbacks of the old methods. Think about it, in the past, all the wires had to be pulled out from the control cabinet. The cabinet was stuffed full, looking like a grocery store, expensive and taking up a lot of space. The wires on site were in a complete mess, like a spider web, and it was extremely difficult to find a wire end to troubleshoot when problems occurred. Now with it, the switch box can be directly installed on the machine, and the cabinet can be made smaller. The site becomes cleaner, with just one network cable handling everything. The best part is, if the equipment breaks down, there's no need to crawl all over the place looking for wires anymore. Just go to the machine and check if the light on the small box is on. The problem is immediately identified, and a lot of work is saved.

Process

The PLC issues the command "Start Motor No. 3"

The command is transmitted at high speed via the DeviceNet network (a sturdy "telephone line")

↓

The command reaches the corresponding channel of the 1792D-CBFM module

↓

The miniature relay inside the module makes a "click" sound and closes the contacts

↓

The external power supply (such as 220V AC) flows through the relay contacts to Motor No. 3

↓

Motor No. 3 starts and begins to operate

Product Application

The Allen Bradley 1792D-CBFM is particularly popular in those dirty and strenuous work environments. For instance, on the assembly line of an automobile factory, it can be placed right next to the robot arm, without worrying about oil stains or vibrations, allowing the robot to grab whatever it needs. In a food processing plant, the equipment needs to be washed with water every day, and it doesn't mind either, because of its high protection level, and it can even be sprayed with a water gun without any problem. And there are those long conveyor belts, where you can install one every certain distance, and separately control the motors and baffles of each section. You can adjust them however you want. In short, wherever control points need to be separated and the environment is not very good, it is the ideal choice.
