The ABB 2TLA010033R0000 (series BT50 24DC Safety Relay) is a safety/expansion relay intended to provide additional safe relay outputs for industrial safety circuits. It can be used to expand the number of safe outputs available from a primary safety device or safety controller, making it easier to control multiple contactors or actuators from a single safety input. The module is powered by 24 V DC, mounts on a DIN‑rail, uses screw terminal connections, and is suitable for applications such as emergency‑stop circuits, safety‑interlocks, gate/door guarding, and safety‑related output expansion.

The ABB 2TLA010030R0000 is a safety‑expansion relay from the E1T series. It is used to expand the number of safe output contacts available from a primary safety relay or safety control unit. When additional outputs are needed — for example to drive multiple contactors or actuators — this module adds four safety‑rated normally‑open (NO) relay outputs. It is powered by 24 V DC, DIN‑rail mountable, and designed to integrate into safety circuits in industrial machinery and control panels.

The ABB 2TLA010027R0100 is a safety expansion relay from ABB’s JSR2A series. It is used to expand the number of safe output contacts available when used together with a primary safety relay or safety controller. The module provides additional relay outputs with higher switching capacity, making it suitable for controlling multiple actuators, contactors or devices in safety‑related circuits. It supports dual‑channel input (when used with appropriate safety wiring) and is designed for DIN‑rail mounting, enabling straightforward integration into industrial control panels.

The ABB 2TLA010028R1000 is a universal safety relay from ABB’s RT7 (RT7B) series. It is designed to monitor safety devices (such as emergency‑stop buttons, safety mats/edges, light curtains/beams, safety switches/interlocks, contact strips, gates/doors, enabling‑devices, foot controls, etc.), in either single‑channel or dual‑channel configuration. On detection of a safety event (e.g. an open guard, a pressed emergency‑stop, or other safety trigger), the relay will switch off its safety contacts to stop or disable the machine/system.

The ABB 2TLA010028R2000 is a universal safety relay (series RT7A) with 24 V DC coil, used for safety‑related control in industrial machinery and systems. It is designed to monitor safety devices such as emergency‑stop buttons, safety switches or interlocks, safety mats/edges, light curtains/beams, contact strips, enabling devices, gates/doors guards — and on fault or unsafe condition, to switch off outputs safely.

The ABB 2TLA020070R4700 is a compact safety‑PLC controller (Pluto S20 v2) designed for machine and system safety applications. It accepts multiple safety device inputs (e.g. emergency‑stop buttons, safety switches, light curtains, safety mats, interlocks, gates/doors, enabling devices, etc.) and evaluates them according to safety logic to control safety outputs. It offers a mix of failsafe relay and transistor outputs plus configurable I/O, enabling flexible and powerful safety‑circuit design. Its programming and configuration are done via dedicated software, making it suitable for small to medium safety systems. The module is DIN‑rail mountable and sized for efficient installation in control enclosures.

The 2TLA020070R4600 is a compact safety PLC (Programmable Logic Controller) from ABB’s “Pluto B20 v2” series. It is designed for machine and system safety applications, allowing direct connection of safety devices (e.g. emergency stops, safety switches, light curtains, mats, interlocks, etc.). The controller supports both failsafe inputs and a mix of relay/transistor outputs, enabling complex safety logic, monitoring, and safe control of machinery. Its built‑in safety bus capability (Pluto Safety Bus) permits expansion and communication with additional safety modules — making it suitable for modular and scalable safety systems. The unit is DIN‑rail mountable and intended for installation in control panels for industrial machinery and process control.

The RT6 115 AC Safety Relay (2TLA010026R0400) is a universal safety relay for industrial safety‑circuit use. It can monitor safety devices like emergency‑stop buttons, safety mats/edges, safety switches/interlocks, light curtains/beams, safety‑switch sensors, enabling devices, gates/doors, or contact strips — either in single‑channel or dual‑channel mode. The relay supports manual supervised reset or automatic reset, and includes safety‑rated relay outputs plus auxiliary “information” outputs and LED status indication. It is DIN‑rail mountable and designed to integrate into control panels to supervise and switch safety circuits reliably.

The ABB 2TLA010026R0500 is a universal safety relay (RT6 series) designed for industrial safety‑circuit monitoring. It supervises inputs from safety devices — such as emergency‑stop buttons, safety mats or edges, light curtains/beams, interlocked gates/guards, enabling devices, foot controls, contact strips — and controls safety outputs accordingly. The relay supports single‑ or dual‑channel input configurations, and allows manual supervised reset or automatic reset, depending on the safety application. It provides multiple safety‑rated relay outputs plus auxiliary “information” outputs to signal the status of safety circuits. The device is mounted on a DIN‑rail and intended for integration into machine control cabinets.

The 2TLA010029R0000 is a safety relay from ABB’s RT9 / “RT9 24DC” series. It is designed to monitor safety devices (such as emergency‑stop buttons, safety mats/edges, light curtains, safety‑switches, interlocks, gates/doors, enabling devices, foot‑pedals, contact strips, etc.) and to provide safety‑rated outputs for reliable machine or system safety. The relay supports both single‑channel and dual‑channel input wiring, making it flexible for different safety circuit designs. It offers selectable manual‑reset or automatic‑reset modes, and includes a “test/reset” or supervision input to verify that external contactors or safety outputs are correctly de‑energized before allowing a restart. The unit is compact, DIN‑rail mountable, and provides LED status indication and a dedicated information output for system monitoring.
