The ABB PPD113B01-26-111000 is a core hardware module of the AC 800PEC (Process and Electrical Control System), specifically designed for scenarios requiring "integration of process control and electrical control" in the industrial sector. It is particularly suitable for precise control needs in high-voltage drives and complex process flows (such as metallurgy, chemical engineering, and energy), and serves as a key component for realizing "electrical-process integrated control" in ABB's industrial automation solutions.

I. Core Positioning and Application Scenarios
The AC 800PEC control system itself is a dedicated system developed by ABB for industrial scenarios that "need to handle both process variables (e.g., temperature, pressure, flow) and electrical variables (e.g., voltage, current, motor speed) simultaneously". As the core module of this system, the PPD113B01-26-111000 mainly undertakes the core functions of "signal acquisition, logical operation, and command output". Its specific application scenarios include:
II. Key Technical Parameters
| Parameter Category | Detailed Specifications |
|---|---|
| Product Model | PPD113B01-26-111000 (dedicated module for AC 800PEC system) |
| Power Supply Requirement | Typically supports DC 24V redundant power supply (complies with industrial anti-interference standards to avoid the impact of voltage fluctuations) |
| Signal Interfaces | Supports analog input/output (e.g., 4-20mA current signals for sensor data acquisition) and digital input/output (e.g., dry contact signals for equipment status detection); some versions are compatible with industrial buses such as Profibus and EtherNet/IP |
| Processing Performance | Equipped with a dedicated industrial-grade processor, supporting multi-task parallel computing; the execution speed of logical instructions can reach the microsecond level, meeting high-frequency control needs |
| Protection Level | The module itself usually has an IP20 protection level (requires matching the overall protection of the control cabinet; the control cabinet is recommended to have IP54 or higher) |
| Redundancy Design | Supports module-level redundant configuration (dual-module hot backup available in some scenarios) to avoid system shutdown caused by single-point faults |
III. Core Functions and Advantages
1. Integration of Process and Electrical Control
Different from the traditional architecture where "process control systems (DCS) and electrical control systems (PLC) are separated", the PPD113B01-26-111000 can process both process variables and electrical variables within the same module, reducing data interaction latency between systems. For example, in the control of chemical reactors, it can simultaneously adjust the "reaction temperature (process variable)" and "stirring motor speed (electrical variable)", achieving more precise process interconnection.
2. High Compatibility and Scalability
3. High Reliability and Fault Protection
