Description
PCD235C101 3BHE057901R0101: Product Overview
The ABB PCD235C101 3BHE057901R0101 is a communication module designed for ABB’s System 800xA distributed control system (DCS), a flagship platform for industrial process automation. As a critical component of the 800xA ecosystem, it acts as a bridge between the DCS controller (e.g., AC 800M) and field devices (e.g., sensors, actuators), enabling real-time data transmission and control.
Role in Automation Systems:
Positioned as a “network interface” in the 800xA DCS architecture, the PCD235C101 performs two primary functions:
-
Protocol Conversion: Translates data between the DCS’s internal communication protocol and fieldbus protocols (e.g., PROFIBUS DP, Modbus TCP), allowing seamless integration of third-party devices.
-
Data Routing: Directs data packets between the controller and field devices, ensuring that process variables (e.g., temperature, pressure) are transmitted accurately and in real time.
Core Functionality:
-
Multi-Protocol Support: Compatible with PROFIBUS DP (up to 12 Mbps), Modbus TCP (10/100 Mbps), and EtherNet/IP, making it versatile for a wide range of industrial applications.
-
Redundant Communication: Supports redundant network configurations to ensure uninterrupted data transmission, critical for mission-critical processes like power generation or chemical processing.
-
Diagnostic Capabilities: Includes built-in status LEDs and fault logging to simplify troubleshooting, reducing mean time to repair (MTTR).
Platform Benefits (System 800xA):
The PCD235C101 leverages ABB’s System 800xA platform, which is renowned for:
-
Scalability: Supports expansion with additional communication modules to accommodate growing operational needs.
-
Reliability: Industrial-grade components and a rugged design ensure 24/7 operation in harsh environments (e.g., high temperature, vibration).
-
Integration: Seamlessly integrates with ABB’s AC 800M controllers and I/O modules, reducing setup time and effort.

Core Features & Customer Value
1. Seamless Protocol Integration:
The PCD235C101’s support for multiple communication protocols (PROFIBUS DP, Modbus TCP, EtherNet/IP) allows it to integrate with a wide range of field devices, including third-party sensors and actuators. For example, in a chemical plant, the module can connect a Siemens pressure transmitter (via PROFIBUS DP) to the ABB DCS, enabling real-time monitoring of reactor pressure.
2. Redundant Communication for Reliability:
The module’s redundant network configuration ensures that data transmission continues even if one network link fails. In a power plant, this means that the DCS can still receive data from turbine sensors even if the primary Ethernet cable is cut, preventing unplanned downtime.
3. Easy Troubleshooting with Diagnostics:
Built-in status LEDs (power, communication, fault) and fault logging simplify troubleshooting. For instance, if a field device stops communicating, the module’s LED will turn red, and the fault log will record the error, allowing technicians to quickly identify and resolve the issue.
4. Compact Design for Space Efficiency:
The PCD235C101’s compact form factor (100 mm × 75 mm × 20 mm) makes it ideal for installations where cabinet space is limited. This is particularly valuable for customers upgrading existing systems, as it eliminates the need for larger control cabinets.

-
Power Generation:
-
Interfaces with turbine sensors (e.g., temperature, vibration) to provide real-time data to the DCS.
-
Example: In a thermal power plant, the module collects data from a turbine temperature sensor and sends it to the DCS, which adjusts the fuel flow to maintain optimal efficiency.
-
-
Water Treatment:
-
Connects pH sensors and flow meters to the DCS, enabling precise control of water quality.
-
Example: In a municipal water treatment plant, the module transmits signals from a pH sensor to the DCS, which adjusts the amount of chlorine added to maintain safe drinking water.
