Description

ABB EI813F 3BDH000022R1

I. Basic Information

• EI: Following ABB's traditional naming logic, E typically stands for Extension Module, and I for Input Module, meaning Input Extension Module.
• 813: Presumed to be a Digital Input Module (DI Module) (comparing EI802F as digital input and EI803F possibly as analog input, "813" may represent the number of channels, voltage type, or upgraded version).
• 3BDH000022R1: ABB product serial number used to identify the specific hardware version (R1 denotes the first revision).
  Type: Digital Input Module (DI Module), used to collect switching signals (e.g., ON/OFF states) from industrial field devices.
  Application Scenarios: Compatible with distributed control systems (DCS) or PLC systems of ABB AC 800M, AC 500-S and other controllers, commonly used in industrial automation, power, process control and other fields.

II. Physical Characteristics

• DIN rail mounting (supports quick disassembly and installation).
• Hot-swapping: Supported by some models (subject to specific specifications).
  Indicators:
• Power Indicator (PWR): Shows the module's power supply status.
• Channel Status Indicators: An LED for each channel to display the real-time signal input status (e.g., illuminated indicates signal conduction).
• Fault Indicator (FAULT): Alerts to module communication or hardware anomalies.

III. Electrical Characteristics

• Presumed to be 16 channels (similar EI802F has 16 channels, and EI813F may continue this configuration).
• Supports dry contact (mechanical switches, relay contacts) or wet contact (24V DC level signals) inputs.
  Electrical Isolation:
• Isolation between channels or groups (e.g., optocoupler isolation) with strong electromagnetic interference (EMI) resistance to prevent signal crosstalk.
• Isolation voltage: Typically 250V AC/DC (ensuring safety and reliability).
  Input Signal Types:
• Dry contacts: Non-powered switch contacts (e.g., buttons, limit switches).
• Wet contacts: Powered level signals (e.g., 24V DC proximity switch outputs).
  Response Time:
• Configurable signal filtering time (e.g., 1-20ms to eliminate mechanical contact bounce).

IV. Environmental Requirements

V. Communication and Functions

• Supports ABB FIELDBUS (direct communication with AC 800M/AC 500-S controllers).
• Can be extended to support fieldbuses such as Profibus DP and Ethernet/IP via gateway modules (additional configuration required).
  Data Transmission:
• Real-time conversion of input signals (0/1 states) into binary data, transmitted to the controller CPU via the backplane bus.
  Diagnostic Functions:
• Channel status monitoring (e.g., signal valid/invalid).
• Open-circuit detection, power failure alarms, communication link diagnostics.
• Fault codes reported to the monitoring system (e.g., ABB Control Builder) via the controller.
  Functional Extensions:
• Supports Sequence of Events (SOE) recording (for some models), accurately logging signal change times (millisecond-level resolution).
• Redundant configuration (requires matching redundant controllers and bus modules).

VI. Working Principle

• Receives switching signals from field devices via terminal modules (e.g., TB series), which enter the module after filtering.
  Signal Conditioning:
• Converts input signal levels (e.g., converts 24V DC signals to internal logic levels) and isolates external interference via optocouplers.
  Analog-to-Digital Conversion:
• Digital signals require no analog conversion and are directly encoded into binary data (e.g., "1" for conduction, "0" for disconnection), stored in registers.
  Data Communication:
• Transmits data to the controller via the module's internal bus, which executes corresponding actions (e.g., alarms, interlock controls) based on preset logic.
  Self-Test and Alarm:
• Periodically detects power, channel, and communication status, alarming via LED indicators and system logs in case of anomalies.

VII. Typical Application Scenarios

• Monitoring start/stop status of production line equipment, detecting safety door switches, and collecting sensor signals (e.g., photoelectric switches, magnetic switches).
  Power Systems:
• Feedback on the position status of circuit breakers and disconnectors, monitoring switch status in power distribution cabinets.
  Process Control:
• Collecting valve switch status, motor operation/fault signals, and high/low level alarm inputs for storage tanks.
  Mechanical Engineering:
• Accessing machine tool limit protection signals, robot IO signal interaction, and equipment safety interlock signals.
