Siemens 6ES7153-1AA03-0XB0 Interface Module for ET 200M

The Siemens 6ES7153-1AA03-0XB0 is an interface module (IM 153-1) for SIMATIC ET 200M distributed I/O, designed to connect ET 200M I/O stations to central PLCs over PROFIBUS DP. It uses RS-485 (PROFIBUS standard) with up to 12 Mbps data transfer, a DP address range of 0–125, and requires 24 V DC supply with approximately 200 mA of current; it includes integrated diagnostics and status LEDs, IP20 protection, and rack-mountable mounting in an ET 200M station operating from 0°C to 60°C. It is commonly deployed in industrial automation racks, process control systems, and PROFIBUS DP networks to enable reliable communication between field devices and central controllers in SIMATIC ET 200M and S7-300 environments. Common replacements include Siemens 6ES7153-2BA02-0XB0 and 6ES7153-2AA02-0XB0; the product is discontinued with spare part availability.
