Siemens 6ES7 151-1AA05-0AB0 Profibus DP Interface Module

Siemens 6ES7 151-1AA05-0AB0 Profibus DP Interface Module is a PROFIBUS DP interface for the SIMATIC ET 200S distributed I/O system, connecting remote I/O to a PROFIBUS network for distributed control. It features a 9-pin D-Sub PROFIBUS port with speeds up to 12 Mbps, a configurable DP station address, and status LEDs for RUN, ERROR, and BUS state. Powered via the ET 200S backplane and mounted on a DIN-rail/module rack within the ET 200S system, the IP20-rated module operates in typical industrial temperature ranges. Common applications include linking SIMATIC ET 200S I/O stations in manufacturing plants, process control, material handling, and building automation where remote sensors and actuators are accessed over PROFIBUS, and it enables real-time data transfer between controllers and remote I/O. Common replacements include Siemens 6ES7 151-1AB01-0AB0, 6ES7 151-1AA01-0AB0, and IM151-1.
