07-7331-230H/1010
Product Identification & Model Breakdown (Product & Model)
This device is a fieldbus interface module belonging to the BARTEC MODEX series of explosion-proof distributed I/O systems.
- Full Model Code:
07-7331-230H/1010 - Product Name: BARTEC MODEX PROFIBUS Analog Interface Module
- Model Structure Breakdown:
- 07-7331-: Product family prefix for BARTEC explosion-proof control and fieldbus modules.
- 230H: Specifies the integrated HART protocol pass-through and PROFIBUS interface configuration.
- 1010: Hardware and channel configuration code (corresponding to a 4-channel analog input / 4-channel analog output mixed setup).
Key Technical Specifications & Features
- Fieldbus Communication: PROFIBUS-DP interface (via RS-485 screw terminals) with onboard DIP switches for quick node address setup.
- Signal Channels & Resolution:
- Signal Type: Standard 4 to 20 mA analog signals
- Channel Count: 4 x Analog Inputs / 4 x Analog Outputs (Ex i Intrinsically Safe)
- Resolution: High-precision 16-bit
- Explosion Protection & Certification:
- Ex Protection Rating: Typically certified as
Ex de [ia] IICor equivalent. - Directly installable inside Zone 1 / Zone 21 hazardous locations. Its field-facing terminals provide Ex i (Intrinsically Safe) outputs, ensuring short circuits will not ignite surrounding explosive atmospheres.
- Ex Protection Rating: Typically certified as
- Diagnostics & HART Integration: Comprehensive diagnostic reporting (e.g., wire break, short-circuit detection via LED indicators and PROFIBUS Telegrams). Supports transparent HART pass-through communication for configuring smart field transmitters.
Application Scenarios (Use Cases)
This module solves the challenge of direct analog signal acquisition and control in hazardous zones while linking back to a central DCS or PLC:
- Hazardous Area Data Acquisition: Collects 4–20 mA signals directly from flow meters, pressure transmitters, and level sensors installed in Zone 1 field areas.
- Hazardous Area Control: Drives control valves, electro-pneumatic positioners, and speed setpoints using its 4–20 mA intrinsically safe outputs.
- Optimized Fieldbus Cabling: Eliminates the need to run dozens of individual 4–20 mA analog cables back to a remote control room. Instead, signals are digitized locally in a field Ex-enclosure and routed over a single PROFIBUS DP trunk line, significantly cutting installation and cabling costs.
Target Industries
Built to strictly comply with international Ex safety standards, this product is heavily deployed across demanding industries:
- Oil & Gas: Offshore drilling platforms, refineries, LNG receiving terminals, and pipeline compressor stations.
- Chemical & Petrochemical: Petrochemical plants, hazardous chemical synthesis units, and tank farm monitoring.
- Pharmaceuticals: Active Pharmaceutical Ingredient (API) reactors and extraction areas using flammable solvents.
- Marine & Offshore: Chemical tankers, LNG/LPG carriers, and engine room monitoring systems.
- Energy & Grain Processing: Combustible dust hazardous zones (e.g., coal handling plants, flour mills, and starch storage facilities).
