By | August 12, 2023

The Allen Bradley 855T BCB wiring diagram is a schematic that shows how the components of the 855T BCB are connected together. It is an important tool for troubleshooting and maintenance, as it can help you identify any problems with the wiring.

The 855T BCB is a programmable logic controller (PLC) that is used in industrial automation applications. It is a versatile controller that can be used to control a wide variety of processes. The 855T BCB has a number of features that make it a good choice for industrial automation applications, including its ability to handle complex logic, its ability to communicate with other devices, and its rugged construction.

The 855T BCB is a complex device, and the wiring diagram can be difficult to understand for someone who is not familiar with PLCs. However, by taking the time to study the wiring diagram, you can learn how the 855T BCB works and how to troubleshoot any problems that may occur.

The 855T BCB wiring diagram is divided into two sections: the power section and the I/O section. The power section shows how the 855T BCB is connected to the power supply. The I/O section shows how the 855T BCB is connected to the inputs and outputs.

The power section of the wiring diagram is relatively simple. The 855T BCB is powered by a 24 VDC power supply. The power supply is connected to the 855T BCB's power terminals. The power terminals are labeled "+24 VDC" and "-24 VDC".

The I/O section of the wiring diagram is more complex. The 855T BCB has a number of inputs and outputs that can be used to connect to sensors, actuators, and other devices. The inputs and outputs are labeled with the following codes:

  • DI: Digital input
  • DO: Digital output
  • AI: Analog input
  • AO: Analog output

The inputs and outputs are connected to the 855T BCB's terminal blocks. The terminal blocks are labeled with the following codes:

  • CN1: Digital inputs
  • CN2: Digital outputs
  • CN3: Analog inputs
  • CN4: Analog outputs

The Allen Bradley 855T BCB wiring diagram is an important tool for troubleshooting and maintenance. By taking the time to study the wiring diagram, you can learn how the 855T BCB works and how to troubleshoot any problems that may occur.
