Description

2. Product Function Description

This hybrid I/O gateway board is a dedicated signal interface module for Honeywell Z local operator console cabinets, serving as the signal bridge between on-site local operation panel instruments and the main TDC3000 control network.
  1. Mixed Signal Collection & Output

    Integrated analog input, analog output, digital input and digital output four types of signal channels, simultaneously collect local panel pressure, flow, temperature analog measurement signals and valve position, equipment running status switch signals; output analog regulation signals and interlock on-off control commands to local field actuators.

  2. Local Console Data Gateway (EPDGP Function)

    Real-time exchange process data, alarm messages, setpoint parameters between Z-Console local operation station and UCN/LCN control bus; realize independent local monitoring and manual operation without relying on central control room HMI.

  3. Signal Isolation & Noise Suppression

    Each channel equipped with independent optocoupler isolation circuit, built-in RC filtering and TVS surge absorption, eliminate ground loop interference and electrostatic surge damage caused by long-distance local panel wiring.

  4. Comprehensive Hardware Self-Diagnosis

    Detect channel open circuit, short circuit, signal over-range, backplane communication loss and module power abnormality; fault information displayed on Z-Console local panel and uploaded to central alarm management.

  5. Harsh Environment Adaptation (-300 core advantage)

    Full PCB acrylic conformal coating against moisture, dust, salt fog and trace corrosive gas, suitable for coastal chemical plants, outdoor auxiliary control rooms, high-humidity power plant local console cabinets.

  6. Hot-Swap Support

    Standard Eurocard plug-in structure, online replacement without powering down the entire Z console cabinet, no interruption of local monitoring functions.

3. Core Electrical Technical Specifications

  1. Integrated Channel Configuration

    • Analog Input: 8 channels 4–20mA standard transmitter signal

    • Analog Output: 4 channels 4–20mA regulating signal for local valves

    • Digital Input: 16 opto-isolated DI channels (24VDC dry contact/active signal)

    • Digital Output: 8 relay isolated DO channels (240VAC/30VDC contact load)

  2. Communication Bus: EPDGP dedicated local console parallel bus, compatible with TPS UCN/LCN network

  3. Power Supply: 24VAC auxiliary power via Z-Console rack built-in transformer

  4. Operating Ambient Temperature: -40℃ ~ +70℃ industrial wide temperature range

  5. Coating Feature: Full heavy-duty anti-corrosion conformal coating (unique mark of -300 model)

  6. Circuit Protection: Per-channel overvoltage/overcurrent protection, ESD & lightning surge suppression

  7. Self-Diagnosis: Channel fault detection, bus heartbeat monitoring, module power abnormal alarm

  8. Mechanical Size: Standard TDC3000 rack Eurocard dimension

  9. Certification: UL industrial safety certification

  10. Power Consumption: Max 2.8W

4. Industrial Application Scenarios

  1. Chemical & Petrochemical Industry

    Reactor, distillation unit on-site Z local operation cabinet signal acquisition and local manual valve adjustment; high humidity corrosive workshop environment relies on the -300 anti-corrosion coating design.

  2. Thermal Power Generation Industry

    Boiler, turbine auxiliary on-site local console mixed I/O signal processing; realize independent local monitoring during central control room maintenance.

  3. Oil & Gas & Coastal Tank Farm

    Coastal compressor station, crude oil storage tank area outdoor local operation panel signal gateway, anti-salt fog corrosion via full conformal coating.

  4. General Process Control

    Water treatment, pharmaceutical factory workshop on-site Z console local control, backup monitoring for central DCS system.
