The 8520-MTB24 is an operator’s panel manufactured by Allen Bradley. It is from the 9/Series, which is one of Allen Bradley’s best in terms of providing accuracy in industrial and manufacturing processes. It comes with an MTB panel, which is based on three different versions of selector pushbuttons and switches. The 8520-MTB24 comes with an LED type Lamp panel and a Direct 24 Volt I/O. The 8520-MTB24 uses the MTB panel to make a connection through the direct 24 Volt DC for inputs and outputs. This feature of the part is especially helpful for switching signals between different CNCs. The 8520-MTB24 weighs 7 pounds and has a height of 20 inches, a width of 10 inches, and depth of 8 inches. It works on a 12 Volt DC power. When installing the part, it is important that an AMP parameter is used to help the user choose between two types of displays, which are either color or monochrome. Fiber optic cables are used to connect the optic ring to the other parts of the 8520-MTB24; however, the removable operator panel is connected to the 8520-MTB24 using only one cable.

The 8520-MTB24 falls under the category of a programmable logic controller (PLC) which is designed to help in a variety of manufacturing processes. It is also highly reliable and generates desired results for accuracy and well as the minimization of industrial losses. Thus, it is used to diagnose any problems or errors that may occur during the manufacturing processes. Moreover, the 8520-MTB24 is used for easy programming and for control over the manufacturing process.
