MTL 8502-BI-DP-1 Bus Interface Module

8502-BI-DP-1 (Standard model: 8502-BI-DP, suffix -1 indicates version 01)
I. Basic Information
Brand: MTL (currently under Eaton, branded by GE Intelligent Platforms)
Product Type: PROFIBUS-DP bus interface module (BIM, Bus Interface Unit)
Series: MTL 8000 Series Intrinsically Safe Barrier System
Origin: United States

Core Functions
As the communication gateway between the MTL8000 series safety barriers and the PLC/DCS master station:
Collects up to 24 on-site signals from the MTL8000 series I/O safety barrier modules
Transmits the signals via the PROFIBUS-DP bus to the control system, supports the HART protocol, and can read the HART parameters of intelligent instruments
Realizes the isolation of safe explosion-proof signals in hazardous areas + centralized collection of the bus, widely used in explosion-proof sites in the petroleum, chemical, and natural gas industries

Key Technical Parameters
Communication Protocol: PROFIBUS-DP V1, compatible with HART
Maximum Baud Rate: 6 Mbaud
Power Supply: 24VDC (isolated power supply), maximum working current 475mA
Operating Temperature: -40℃ ~ +70℃
Installation Method: DIN rail installation
Explosion-proof Certification: ATEX, IECEx safe explosion-proof certification, applicable to Class I, Division 2 hazardous areas
Protection Grade: IP20

Model Description
8502-BI-DP-1 = Standard version 8502-BI-DP hardware version 01, electrically and functionally fully compatible, can be directly interchanged.
V. Typical Application Scenarios
Explosion-proof conditions in chemical DCS systems, oil refining, oil and gas extraction, pharmaceuticals, etc., combined with MTL analog and digital safety barriers, will centrally connect the on-site 4-20mA/HART instrument signals through the DP bus to the control system.
