Product Identification & Model Breakdown

This device belongs to the BARTEC MODEX family of explosion-proof decentralized fieldbus I/O modules.

• Model Number: 07-7331-2304/0000 (often formatted without slashes as 07-7331-23040000)
• Product Name: BARTEC MODEX PROFIBUS Interface Module (8 x 4 to 20 mA Inputs, Ex i)
• Model Designation Breakdown:
  • 07-7331-: BARTEC’s MODEX product line code for PROFIBUS-DP fieldbus components.
  • 2304: Represents an 8-channel analog input module configuration designed for standard 4–20 mA signals.
  • /0000: Specifies the Ex i (Intrinsically Safe) version designed for direct connection to 2-wire field transmitters.

Key Technical Specifications & Features

• Input Channels: 8 x Analog Inputs (4 to 20 mA)
• Power Supply for Field Devices: Built-in intrinsically safe power supply to power up to eight 2-wire transmitters directly.
• Signal Resolution: 12-bit analog-to-digital conversion.
• Fieldbus Protocol: PROFIBUS-DP interface.
• Node Addressing: Dual rotary switches on the module front panel for quick manual address configuration (addresses 01–99).
• Explosion Protection Marking: Certified as Ex db e [ia Ga] IIC Gb (or Ex de [ia] IIC) for installation directly in Zone 1 / Zone 21 hazardous areas.
• Explosion Safety Concept: The module enclosure uses Flameproof (Ex d) and Increased Safety (Ex e) protection, while the field terminals are Intrinsically Safe (Ex i), ensuring field loops cannot spark or overheat even under fault conditions.
• Onboard Diagnostics:
  • LED indicators for Bus Status (ON, BF – Bus Fault, SF – System Fault).
  • Yellow/Red channel LEDs for monitoring individual input activity, open circuits (wire breaks), and short circuits.

Application Scenarios (Use Cases)

1. Hazardous Sensor Signal Collection: Collecting process variables (pressure, flow rate, temperature, level) from up to 8 separate 2-wire intrinsically safe transmitters located inside Zone 1 or Zone 2 hazardous areas.
2. Eliminating Long-Distance Cable Runs: Placing the module in a field-mounted Ex-enclosure close to the process instruments. Sensor signals are digitized locally and sent back to a central PLC or DCS via a single PROFIBUS DP cable, dramatically lowering wiring and installation costs.
3. Automated Fault Detection: Instantly detecting wire breaks or shorted sensor loops directly at the field level and alerting operators via fieldbus diagnostic telegrams and LED indicators.

Target Industries

Because of its heavy-duty Ex construction and high reliability, this module is widely used across harsh process industries:

• Oil & Gas (Upstream & Downstream): Offshore platforms, FPSO vessels, oil refineries, and gas compression stations.
• Chemical & Petrochemical: Petrochemical synthesis plants, distillation columns, and chemical storage tank farms.
• Pharmaceutical Manufacturing: Production areas utilizing volatile solvents or flammables.
• Marine & Offshore: LNG/LPG transport vessels and chemical tankers.
• Bulk Powder & Grain Handling: Areas with combustible dust hazards (e.g., coal handling, flour mills, and starch silos).
