Working Principle of ABB PDD200A101 3BHE019633R0101 Module(1) Signal Acquisition and Processing Mechanism

• Multi-type Signal Access

• DI receives switch signals (such as circuit breaker status, button commands) and eliminates interference through optoelectronic isolation circuits.

• DO outputs relay/transistor switch signals to control the start/stop of contactors, indicator lights, and other devices.

• Analog Input (AI): Receives 4-20mA/0-10V signals from sensors (such as current/voltage transformers, temperature sensors), and converts them into digital quantities (e.g., 12-bit/16-bit precision) through ADC (Analog-to-Digital Converter) for real-time monitoring of equipment status (such as current, voltage, temperature).

• Analog Output (AO): Converts digital control signals into analog quantities through DAC (Digital-to-Analog Converter) to drive actuators (such as regulating valves, frequency converter set values) for continuous adjustment.

• Digital Input/Output (DI/DO):

• Real-time Data Processing Logic

• Built-in DSP (Digital Signal Processor) or FPGA (Field-Programmable Gate Array) performs real-time calculations (such as filtering, PID control algorithms) on collected signals, with response speeds reaching microsecond levels (suitable for high-frequency control scenarios).

• Supports custom logic programming (such as through ABB's PLC programming software) to achieve signal threshold judgment and fault logic interlocking (such as cutting off DO output during overcurrent protection).

(2) Communication Protocols and System Interconnection

• Industrial Bus Communication

• Upward Transmission: Sends collected equipment data (such as operating parameters, fault codes) to the main control system.

• Downward Reception: Receives control commands from the main control system (such as start/stop signals, parameter setting values), parses them, and drives I/O outputs.

• Compatible with mainstream protocols (such as Modbus RTU, EtherNet/IP, Profibus DP) or ABB's proprietary protocols (such as DriveCOM), and communicates bidirectionally with the main control system (such as PLC, host computer) through RS-485, Ethernet ports, or fiber interfaces:

• Communication Isolation and Anti-interference

• The communication interface is built-in with isolation transformers or optocouplers to prevent external electromagnetic interference (EMI) from affecting data transmission, complying with industrial electromagnetic compatibility standards such as EN 61800-3.
