Overview

The MTL 8502-BI-DP Bus Interface Module (BIM) provides a reliable communication bridge between MTL8000 series I/O modules and a Profibus-DP host system. Acting as a Profibus slave, it ensures cyclic data exchange for inputs and outputs while supporting Profibus Extended Diagnostics for detailed monitoring.

The module also supports HART® process and status variables, allowing engineers to access device-level information directly over Profibus. Its non-volatile memory preserves configuration data during power interruptions, enhancing system stability. With LAN speeds up to 6 Mbaud, it delivers fast response times for mission-critical control applications.

This module reflects Eaton/MTL’s expertise in industrial networking, making it widely adopted in sectors requiring high-speed, reliable communication between distributed control systems (DCS) and field devices.

Technical Data

Typical Applications

The 8502-BI-DP is widely used in distributed process and automation networks, including:

• Process automation – Connecting chemical and petrochemical plant I/O modules to Profibus-DP hosts.

• Power generation – Integrating turbine and boiler monitoring systems with DCS networks.

• Oil & Gas facilities – Providing safe and reliable communication between hazardous area devices and control systems.

• Factory automation – Supporting high-speed PLC-based data acquisition and control.

• SCADA networks – Enabling HART® diagnostics and device maintenance over Profibus.

Its support for up to 24 I/O modules makes it ideal for large-scale, scalable automation projects requiring redundancy and advanced diagnostics.
