The RT6 (2TLA010026R0200) is a universal safety relay from ABB’s RT‑series, designed for machine and system safety applications. It monitors inputs from safety devices (e.g. safety mats, light curtains, emergency stops, contact strips, interlocks) and provides safety‑classified outputs that trigger stops or safety actions when needed. The relay supports both manual and automatic reset, includes status‑LED indicators and information outputs, and can replace multiple simpler relays thanks to its flexible input/output configuration. It is mounted on a 35 mm DIN‑rail and suited for controlling safety circuits in industrial machinery.

The CM‑SRS.21S is a single‑phase current‑monitoring relay from ABB’s CM‑SRS series. It monitors AC and/or DC current and triggers an output when the measured current goes above or below a set threshold — providing either over‑current or under‑current protection. The device supports multiple measuring ranges for flexibility, and allows adjustment of hysteresis and tripping delay. Output is provided via dual changeover (SPDT) contacts, and the relay is designed for DIN‑rail mounting with standard screw‑type terminals.

The SDCS‑IOB‑23 is an external, isolated digital I/O interface board designed for industrial automation control systems. It serves as an add-on I/O module for ABB drive and control units, providing externally accessible, galvanically isolated digital inputs and outputs.

The CM‑MPS.21S is a three-phase multifunction monitoring relay from ABB’s CM‑MPS series. It continuously monitors three-phase supply voltage and phase conditions, protecting electrical systems by detecting faults such as phase failure, incorrect phase sequence, over-voltage, under-voltage, and phase unbalance. When a fault occurs, the relay triggers via its output contacts.

The CT‑MXS.22S is a multifunction electronic time relay in ABB's CT‑S timer series. It combines multiple timing functions in a compact unit for industrial applications. It supports five different timing functions and offers adjustable time ranges from 0.05 seconds up to 300 hours. The relay can be triggered via a voltage-related control input and allows connection of two remote potentiometers for precise time adjustments.

The ABB 1SVR730021R2300 is a multifunction electronic time relay in the CT‑S timer series. It provides broad flexibility for timing and control in automation, electrical control panels, motor control centers, or industrial installations. It supports up to 10 different timing functions (including ON‑delay, OFF‑delay, impulse‑ON, impulse‑OFF, symmetrical ON/OFF delay, pulse generator, star‑delta change‑over, pulse former, and basic ON/OFF functions), and offers a wide adjustable time range from 0.05 seconds up to 300 hours, allowing very short delays to very long delays in one device.

The ABB CT‑ERS.22 is a compact, single‑function electronic ON‑delay timer relay. When control supply voltage is applied, the relay waits for a user‑selected delay time, then changes its output contacts from their default state. Its slim 22.5 mm width and DIN‑rail mountable housing make it suitable for installation in control panels, automation cabinets, and other industrial or commercial electrical control systems. The relay supports a wide supply‑voltage range, accommodates many delay‑time settings, and uses SPDT (change‑over) contacts to control downstream loads or contactors, making it a versatile timing device for automation, motor control, lighting, sequential logic, and general‑purpose time‑delay applications.

The ABB CT‑ERS.22S is a single‑function electronic ON‑delay (delay‑on‑make) timer relay from ABB’s CT‑S timer family. It provides delayed switching functionality: when control power is applied, it waits for a preset delay period, then activates its output contacts. With adjustable time ranging from very short to very long (0.05 second up to 300 hours), the CT‑ERS.22S is suitable for many timing applications in automation, motor control, lighting control, delay‑on‑start, sequential control circuits, or machine control panels. It is compact, DIN‑rail mountable, with a slim 22.5 mm width — making it easy to integrate into control cabinets and distribution panels. The relay includes 2 change‑over (SPDT) contacts, so it can drive loads (directly within rating) or control contactors/other devices following the time delay.

The ABB CT‑ARE is a compact, single‑function electronic time relay from ABB’s CT‑E timer range. It provides a true OFF‑delay (delay‑on‑break) function: when the control supply voltage is removed, the relay keeps its output energized for a preset delay time, then de‑energizes. It does not require a separate auxiliary supply — timing works directly based on the control supply voltage applied to its input. With simple adjustment of the delay time via a thumbwheel, and a straightforward 1 change‑over (SPDT) output, CT‑ARE is designed for cost‑efficient, reliable timing tasks in control panels, automation systems, motor control, lighting control, or sequential switching circuits. The device is slim (22.5 mm wide), DIN‑rail mountable, and features a front‑panel LED to indicate supply status.

The ABB CT‑SDE 1SVR550217R4100 is a single‑function electronic time‑relay belonging to ABB’s “CT‑E” timer family. It is designed to provide a star‑delta (star‑triangle) time‑delay function — typically used for motor starting circuits that need to begin in “star” configuration, then automatically switch to “delta” after a preset time. The relay allows a delayed change‑over when starting motors, which reduces the starting current and mechanical stress. It is compact, DIN‑rail mountable, and uses screw‑terminal connections. The device offers a small mechanical footprint, making it suitable for control panels, motor control centers (MCC), automation cabinets, or motor‑starter assemblies
