The ABB RLY‑DMJ45R‑01 is a gas density monitoring relay / sensor for use in electrical apparatus that uses insulating gas (e.g., sulfur hexafluoride, SF₆). It measures the gas density inside the equipment and actuates built‑in relay contacts when the density goes above or below defined limits. This helps protect equipment by triggering alarms or interlocks when gas pressure/density is outside safe operating ranges.

The ABB PM564‑T‑ETH is a programmable logic controller (PLC) CPU module from ABB’s AC500‑eCo series. It integrates high‑performance control and Ethernet communication in a compact design, ideal for industrial automation tasks requiring real‑time control, data exchange, and seamless network integration.

The ABB PSTX370‑600‑70 is an advanced three‑phase soft starter designed to improve motor start/stop performance for medium‑ and large‑sized AC motors. It allows smooth acceleration and deceleration using adjustable voltage or torque ramps, minimizing mechanical wear and electrical stress on the system. The unit includes a built‑in bypass for energy savings and easy installation, Modbus RTU communication for monitoring/control, and advanced built‑in functions like current limiting, kickstart, jog, braking, and emergency modes. This soft starter is suitable for pumps, fans, compressors, conveyors and other industrial motor applications.

The ABB DCS550‑S01‑0135‑05‑00‑00 is part of ABB’s DCS550 standard DC drive family, designed to precisely control DC motors by converting three‑phase AC input into a controlled DC output. This non‑reversing (2‑quadrant) drive supplies controlled DC armature current and enables controlled forward operation and braking of the motor. The DCS550 series is compact, features an integrated field exciter, and offers advanced features like built‑in PID control, adaptive programming, extensive fieldbus communication options, and easy commissioning tools — making it suitable for new machine designs or retrofit projects.

The ABB DCS550‑S01‑0180‑05‑00‑00 is a standard non‑reversing DC drive rectifier module designed to control the armature current of DC motors in industrial applications. It forms part of the DCS550 drive family, which offers compact design, integrated field excitation support, and optional communication interfaces for flexible integration into automated systems. This unit specifically is built to provide up to 180 A DC current at a DC bus voltage of around 525 V, making it suitable for medium‑power DC motor applications where precise speed and torque control are needed.

The ABB DCS550‑S01‑0900‑05 is an advanced industrial DC drive designed for speed and torque control of DC motors in medium‑to‑heavy industrial applications. It is part of ABB’s DCS550 series DC drives, noted for flexibility, integrated field excitation, and extensive integration options for machine builders and retrofits.

The ABB DCS800‑S01‑0180‑05 is a non‑regenerative industrial DC drive designed to control DC motors by converting three‑phase AC input power into a controlled DC output. It is part of the ABB DCS800 family of digital DC drives, providing robust performance for demanding industrial environments. This type of drive offers precise speed control, adjustable current limits, and fault diagnostics, making it suitable for applications where DC motor speed and torque regulation is required. The unit operates without regenerative capability (2‑quadrant control), meaning it manages forward motor operation and braking through controlled DC output, but it does not return energy to the electrical supply during deceleration.

The ABB ACS355‑03E‑08A8‑4 is a three‑phase variable frequency drive (VFD) optimized for controlling AC motors in a wide range of machinery applications. It supports smooth speed control, energy‑efficient operation, and built‑in safety features like Safe Torque Off (STO). Its modular design makes it easy to install and set up, and it includes options for EMC filtering and communication interfaces to suit different automation needs.

AYK550-UH-038A-4+K465 VFD (also referenced as AYK550‑UH‑038A‑4+K465) is a variable frequency drive (VFD) used to control the speed and torque of AC electric motors, often in HVAC (Heating, Ventilation, and Air Conditioning) and industrial motor applications. It is designed to optimize motor performance, improve energy efficiency, and provide smooth speed control.

The ABB 1SVR703824R9300 (often listed as 1SVR730824R9300) is a three‑phase monitoring relay from ABB’s CM‑PFS.S series. It is designed to monitor the health of a three‑phase AC power supply by checking for issues such as phase sequence errors, phase failure, over‑ and under‑voltage conditions, and phase unbalance. When an abnormal condition is detected, the relay changes the state of its control outputs to signal or protect equipment. The compact relay is DIN‑rail mountable and suitable for industrial control panels and automation systems where reliable phase monitoring is required.
