MTL 8502-BI-DP Profibus-DP Bus Interface Module
MTL 8502-BI-DP (often marked as 8502-B1-DP) is a Profibus-DP bus interface module under Eaton MTL 8000 series I/O system. It serves as a communication gateway, connecting MTL 8000 remote I/O modules to Profibus-DP master hosts such as PLC and DCS controllers.
This module supports up to 6 Mbaud baud rate and can drive a maximum of 24 I/O modules. It supports HART transparent transmission and extended bus diagnosis, widely used in petrochemical, oil & gas hazardous area control cabinets for spare replacement.
