The Siemens QAE2174.015 is an active immersion temperature sensor from the Symaro series, designed for measuring water temperature in pipes and tanks within HVAC and building automation systems . It is specifically configured for DC 13.5…35 V supply (DC-only, not AC) and provides a 4…20 mA linear output signal corresponding to a factory-set measuring range of -10…120 °C. The sensor uses a Pt 1000 Class B sensing element per DIN EN 60 751, housed in a 150 mm stainless steel immersion rod with a G ½" process connection . It is a current, active product (PLM status PM300) with a standard factory lead time of approximately 1 day.

The Siemens SQM10.16562 is a robust electromotoric actuator (servomotor) designed for the precise positioning of gas and air dampers on medium to large industrial burners. It is part of the SQM10 series, which is distinguished from the compact SQN series by its heavy-duty die-cast aluminum housing and high-torque gearing, making it suitable for demanding combustion applications in industrial kilns, marine boilers, and large process heaters. The actuator operates on 220–240 V AC and provides a nominal torque of 10 Nm, with a counterclockwise (CCW) rotation direction when facing the drive shaft. It uses a reversible synchronous motor and a traditional cam-and-switch mechanism for reliable position feedback and limit switching, integrating seamlessly with burner management systems (BMS) such as the Siemens LMV series.

The Siemens 6DD7050-0AA70 is an MFI (Multi-Function Interface) expansion module designed for the SIMATIC TDC (Technology and Drive Control) automation system. It is specifically used as an expansion module for the CPU551 controller module, providing additional high-speed interface and signal output capabilities essential for complex drive and technology applications. The module serves as a critical interface expansion within the TDC platform, adding TDM-BUS (Time Division Multiplex) interface, CONTROL-BUS interface, and dedicated firing pulse / pulse harp outputs. These capabilities are particularly relevant for applications requiring precise synchronization and control of power electronics, such as in drive systems and specialized industrial control.

The Siemens 6SL3224-0BE41-1UA0 is an unfiltered PM240 Power Module from the SINAMICS G120 modular drive system, designed for high-power industrial motor control. Rated at 132 kW for low overload (LO) and 110 kW for high overload (HO), it operates on a 380–480 V 3 AC supply and includes an integrated braking chopper for dynamic braking applications. This module is the power section of a modular G120 drive and requires a separate Control Unit (such as CU240E-2 or CU250S-2) to form a complete frequency converter. The unfiltered design makes it suitable for installations where an external EMC filter is used or where the supply system configuration requires an unfiltered drive. Siemens currently lists this product as a spare part only, with the PM240-2 series designated as the successor.

The Siemens 6EP3436-8SB00-0AY0 is a SITOP PSU8200 stabilized power supply designed for demanding industrial applications. It accepts a 3-phase 400–500 V AC input (wide range 320–575 V AC) and delivers a regulated 24 V DC / 20 A output (480 W), providing reliable power for PLCs, I/O modules, sensors, and other 24 V DC loads in control cabinets. The PSU8200 series is engineered for high performance and reliability, featuring 94% efficiency, a compact metal housing, and comprehensive protection functions including short-circuit protection with selectable constant current or latching shutdown modes. It is classified under Siemens PLM status PM300: Active Product, ensuring ongoing availability and support.

The Siemens 3RF2120-1AA04 is a single-phase SIRIUS 3RF2 solid-state relay designed for wear-free, noiseless switching of resistive and inductive AC loads. Rated at 20 A (AC-51) with a 48–460 V AC operating voltage range, it is controlled by a 15–24 V DC signal and uses screw terminals for main circuit connections. Unlike electromechanical relays, this solid-state device has no moving parts, making it ideal for high-switching-frequency applications and noise-sensitive environments. The compact 22.5 mm width saves valuable space, and the unit can be expanded with standardized 3RF29 function modules for load monitoring, power regulation, or terminal covers.

The Siemens 6SL3224-0BE31-5UA0 is an unfiltered PM240 Power Module from the SINAMICS G120 modular drive system, designed for controlling three-phase AC motors in industrial applications. Rated at 18.5 kW for low overload (LO) and 15 kW for high overload (HO), it operates on a 380–480 V 3 AC supply and includes an integrated braking chopper for dynamic braking applications.

The Siemens 3RF2150-1AA04 is a single-phase SIRIUS 3RF2 solid-state contactor designed for wear-free, noiseless switching of resistive and inductive AC loads. Rated at 50 A (type current) with a 48–460 V AC operating voltage range, it is controlled by a 15–24 V DC signal and uses screw terminals for main circuit connections. Unlike electromechanical contactors, this solid-state device has no moving parts, making it ideal for high-switching-frequency applications and noise-sensitive environments such as hospitals, offices, or bottling plants. The compact 22.5 mm width saves valuable space on the heatsink, and the unit can be expanded with standardized 3RF29 function modules for load monitoring or power regulation.

The Siemens 6ES7195-7HD80-0XA0 is a SIMATIC DP Bus Module (BM IM157) designed for use with the IM157 and IM153-2 interface modules in the ET 200M distributed I/O system. It is specifically engineered for extended temperature range applications and supports the "removal and insertion during operation" (hot-swap) function, allowing modules to be replaced while the system remains powered and running . This bus module serves as the physical and electrical backbone for the ET 200M station, providing the connection interface between the interface module and the I/O modules. The extended temperature range capability makes it suitable for deployment in harsh industrial environments where standard temperature-rated components may not be sufficient.

The Siemens 6ES7951-1KK00-0AA0 is a SIMATIC S7 memory card designed for the S7-300 series of programmable logic controllers. It uses 5V Flash EPROM technology with a capacity of 1 MB, providing non-volatile storage for user programs and configuration data in the compact "short design" form factor. This memory card serves as external load memory for S7-300 CPUs, allowing the user program to be stored independently of the CPU's internal RAM. The Flash EPROM technology retains data without requiring a backup battery, making it suitable for applications where program integrity must be maintained through power cycles.

The Siemens 6EP1961-3BA21 is a SITOP PSE202U redundancy module designed to decouple two SITOP power supplies for building a redundant 24 V DC power system. It accepts input from two separate power supplies (each up to 20 A) and delivers a combined output of up to 40 A, ensuring continuous power to critical loads even if one supply fails.

The Siemens AZL52.00B1 is the dedicated display and operating unit for the LMV5 series of burner management systems, including the LMV51 and LMV52 platforms. It serves as the primary human-machine interface (HMI) for commissioning, parameterization, diagnostics, and monitoring of industrial combustion systems.
