The Siemens 6SE7090-0XX84-0AH2 is a T300 Technology Board for the SIMOVERT MASTERDRIVES drive platform. It is a plug-in option board that adds supplementary process-specific functions—such as tension control, winder control, angular synchronism, positioning, and hoisting gear functions—to the drive's core control capabilities. This board is the direct successor to the 6SE7090-0XX84-0AH0 (T300). According to Siemens Industry Support, the AH2 is a hardware revision of the same T300 platform, with no programming differences between the two versions. The only practical migration note is that the MS300 module must be transplanted from the old board to the new one.

The Siemens 6SE7035-1EJ84-1JC1 is an IGD7 Inverter Gating Module for the SIMOVERT MASTERDRIVES platform. It is a customer-specific engineered board that provides the gate firing control for high-current inverter units in the 510 A equipment class, operating with a 3 AC 380–460 V input and a 510–620 V DC link. This module is not a complete inverter or a control unit—it is the dedicated gating board that drives the power semiconductors in the inverter section of a MASTERDRIVES chassis unit. Siemens has identified 6SE7035-1EJ84-1JC2 as the official successor, though it is a migration reference rather than a guaranteed drop-in replacement.

The Siemens 6GK1901-1BB10-2AE0 is the 50-piece bulk pack of the IE FC RJ45 Plug 180 2x2 Industrial Ethernet connector . It is the same connector as the 1-piece (2AA0) and 10-piece (2AB0) versions, just supplied in a larger quantity for panel builders or high-volume installations.

Siemens 6FM1723-3AA00 is a Positioning Module WF 723 for the SIMATIC S5 platform. It is a legacy component that has been out of production for many years.

The Siemens 6FM1470-4BA25 is a monochrome display module (WF 470B) for the SIMATIC S5 platform, not a modern video display or a motor control component. Multiple European industrial spare parts suppliers consistently describe it as a display module with 3 memory submodule slots and a second serial interface.

The Siemens 6DR5220-0EN00-0AA0 is a SIPART PS2 smart electropneumatic positioner designed for precise control of double-acting pneumatic linear and part-turn actuators. It operates on a 4…20 mA signal (2/3/4-wire) with HART communication, and is supplied in a polycarbonate enclosure with intrinsic safety (Ex i) protection for hazardous area applications.

The Siemens 6GK1901-1BB10-2AB0 is an Industrial Ethernet FastConnect RJ45 plug designed for field assembly of IE FC TP 2x2 installation cables. It features a 180° cable outlet, a rugged metal housing, and Siemens' FastConnect insulation displacement technology for tool-free, rapid termination in the field. This is the 10-piece pack version (the 1-piece version is 6GK1901-1BB10-2AA0). The connector supports 10/100 Mbit/s Industrial Ethernet transmission and is rated Cat5 for structured cabling. It is a standard, active Siemens product (PLM status PM300) with a typical factory lead time of 1 day.

The Siemens 6GK5216-0BA00-2AB2 is a SCALANCE XB216 managed Layer 2 industrial Ethernet switch designed for control cabinet networking in factory automation. It features 16 × 10/100 Mbit/s RJ45 copper ports and 1 console port, providing high port density for connecting PLCs, HMIs, drives, and other Ethernet devices within a single machine or production cell. As a managed switch, the XB216 supports ring redundancy (MRP, HRP, RSTP), VLAN, and network diagnostics, making it suitable for applications requiring network reliability and visibility beyond what an unmanaged switch can provide. It is certified as a PROFINET IO Device (Conformity Class B) and supports EtherNet/IP, enabling seamless integration into both PROFINET and EtherNet/IP automation architectures.

The Siemens 6EP1961-2BA00 is a SITOP select diagnostic module designed to provide selective protection for 24 V DC load circuits. It distributes a single 24 V DC input (up to 40 A) across 4 independently protected output channels, each rated for 10 A and adjustable from 2 to 10 A via potentiometer.

The Siemens 3TK2821-1CB30 is a SIRIUS 3TK28 series safety relay designed for monitoring emergency stop circuits and protective doors in industrial machinery. It operates on 24 V AC/DC supply and provides 3 Normally Open (NO) safety outputs plus 1 Normally Closed (NC) signaling contact, with screw terminals for wiring.

The Siemens 6GK1571-0BA00-0AA0 is the PC Adapter USB A2, a USB-to-PROFIBUS/MPI interface designed to connect a programming device (PG), PC, or notebook to SIMATIC S7 controllers. It is the successor to the legacy 6ES7972-0CB20-0XA0 adapter and supports PROFIBUS transfer rates up to 12 Mbit/s, a significant improvement over the older model's 1.5 Mbit/s limit.

The Siemens 6GK5004-2BF00-1AB2 is a SCALANCE XB004-2LD unmanaged industrial Ethernet switch designed for setting up small star and line topologies in industrial environments. It features 4 × 10/100 Mbit/s RJ45 copper ports and 2 × 100 Mbit/s single-mode SC fiber ports, enabling cost-effective connection of distant network participants up to 26 km away.
