The 2TLA010033R2000 (series BT51 24 VDC) is a safety / expansion relay designed for industrial safety applications such as emergency stop circuits, safety‑interlocks, gate/guard/machine‑door monitoring, and safety output expansion. It accepts safety device inputs (e.g. emergency‑stop pushbuttons, safety‑switches, interlocks) and provides four safety‑rated outputs to simultaneously control several actuators or contactors. The relay includes internal supervision and a “test/reset” input to verify that downstream contactors or valves have actually opened before allowing a restart — ensuring a safe reset sequence. The unit is DIN‑rail mountable, compact (22.5 mm width), and suitable for integration into control cabinets.

The Adam DYN‑Info M12‑5 (part number 2TLA020051R5100) is a non‑contact safety sensor from the Eden series by ABB / Jokab Safety. It is designed for safety interlocking and safe‑position monitoring — for example on doors, guards or machine enclosures. The sensor works in combination with a matching actuator (typically an “Eva” actuator): Adam senses the presence of Eva magnetically, without mechanical contact, so there is no mechanical wear and the system is more robust. Its compact size, IP67 / IP69K protection, and 360° mounting flexibility make it suitable for industrial environments and harsh conditions. The sensor provides a DYNlink output / “information” signal output for connection to safety controllers or safety relays, enabling reliable safety logic integration.

The ABB 2TLA020051R5700 is a non‑contact safety sensor unit (part of the Jokab Safety “Eden” series) — specifically the “Adam OSSD‑Info M12‑8” type. It is designed for safety interlocking, door/guard locking, and safe‑position monitoring. The sensor detects a matching actuator (from the “Eva” series) without mechanical contact, eliminating wear and providing high reliability. Because it uses OSSD (Output Signal Switching Device) outputs with safety‑rated logic, it can be used with compatible safety controllers/relays for safety‑relevant functions. The compact housing, M12‑8 male connector, and robust IP67/IP69K protection make it suitable for industrial environments, including harsh or wet conditions.

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.
