PLC Controller

The Siemens 6SL3210-1KE26-0UF1 is a compact SINAMICS G120C variable frequency drive designed for versatile industrial motor control. It is a three-phase drive rated at 30 kW (40 HP) for low overload applications, featuring an unfiltered design and a PROFINET / EtherNet/IP fieldbus interface for seamless integration into modern automation networks.

The Siemens C79458-L2428-A1 is a TCD (Thermal Conductivity Detector) board used in the Siemens PGC302 process gas chromatograph. It is the dedicated electronic board responsible for processing the signal from the TCD cell, which is the core detector used in gas chromatography to analyze the concentration of gas components. According to a Siemens PGC302 manual excerpt, the board is explicitly listed under "Detector boards" as the "TCD-board C79458-L2428-A1" . Aftermarket spare parts suppliers describe it as an "electronic board for TCD" or "WLD P302 E-1 electronic board for TCD".

The Siemens 6GK1901-0AA00-0AA0 is a SIMATIC NET SINEC H1 bus coupler (transceiver) with one interface, used to connect a terminal or control device (such as a SIMATIC S5 PLC) to an industrial SINEC H1 coaxial/triaxial network.

The Siemens 6GK1543-1AA01 is a SINEC CP5431 FMS/DP communication processor designed for the SIMATIC S5 PLC platform. It connects legacy S5 controllers—specifically the S5-115U/H, S5-135U, and S5-155U/H—to PROFIBUS networks, enabling data exchange with distributed I/O, drives, and higher-level automation systems. This module is the FMS/DP variant of the CP5431 series. It is important to distinguish it from the CP5430 TF (6GK1543-0AA02), which is a different card with Technology Function capability. The 6GK1543-1AA01 is the designated replacement for the discontinued CP5430 TF, but the two are not functionally identical—verify your application requirements before substituting.

The Siemens 6GK1543-0AA02 is a SINEC CP5430 TF (A2 version) communication processor designed for the SIMATIC S5 PLC platform. It serves as an interface module that integrates legacy S5 controllers (115U, 135U, and 155U) into SINEC L2 / PROFIBUS networks, enabling data exchange between the PLC and higher-level automation systems. 

The Siemens 6GK1543-0AA01 is a CP 5430 TF communications processor for the SIMATIC S5 automation system.

The Siemens 6GK1500-0EA02 is a SIMATIC NET PROFIBUS bus connector (RS 485), primarily used for connecting devices—such as industrial PCs, SIMATIC OP operator panels, and OLMs (Optical Link Modules)—to a PROFIBUS network.

The Siemens 6GK1500-0DA00 is a PROFIBUS RS 485 Bus Terminal featuring a fitted PG interface and a 1.5-meter connecting cable. It is part of the SIMATIC NET product line used for industrial communication networks.

The Siemens 6GK1415-2AA01 is the DP/AS-Interface Link 20E (V2.11), a gateway module that translates data between a PROFIBUS DP network and an AS-Interface (AS-i) network.

The Siemens 6GK1243-3SA00 is the catalog number for the CP 2433 (SINEC S1 Master / AS-Interface communication processor).

The Siemens 6GK1143-0TB01 is a SIMATIC NET CP 1430 TF industrial communication processor module manufactured by Siemens.

6GK1143-0TA02 is the ordering number for the SIMATIC NET CP 1430 TF Basic communications processor by Siemens, designed to connect SIMATIC S5 programmable logic controllers (specifically S5-135U and S5-155U/H PLCs) to Industrial Ethernet using the SINEC H1 protocol.
