The SSR10 is a compact safety relay in the “Sentry” family by ABB. It is used to monitor safety devices (such as emergency‑stop buttons, safety switches/interlocks, light curtains / OSSD‑output devices, or other contact‑type safety devices) in either single‑channel or dual‑channel mode. The relay evaluates the safety inputs and provides safety‑rated relay outputs when conditions are satisfied. A front‑panel switch allows selection between manual‑reset or automatic‑reset behavior. The SSR10 is designed for DIN‑rail mounting with screw‑terminal wiring, making it easy to integrate into machine safety circuits or control cabinets for industrial machinery.

The SSR32 (2TLA010052R0400) is a compact safety relay designed to monitor safety devices — such as emergency‑stop buttons, safety switches/interlocks, light‑curtains or OSSD safety outputs — in either single‑channel or dual‑channel mode. It evaluates the safety inputs, and when safety conditions are met, provides safety‑rated relay outputs. The relay supports either manual‑reset or automatic‑reset (selectable via a switch on the front). It also incorporates a built‑in timing function: two of its relay outputs are “delayed‑OFF” (i.e. they switch off with a 0.5 s delay), which can be used to implement a “soft stop” or delayed shutdown. The module is DIN‑rail mountable, uses screw‑terminals, and is suited for installation in control cabinets for machine‑safety circuits.

The BT51T 24DC safety relay is a compact universal/expansion safety relay designed to monitor safety devices (e.g. emergency‑stop buttons, safety switches/interlocks, safety mats/edges, light‑curtains, gates/doors) and provide multiple safety‑rated outputs. It accepts either single‑ or dual‑channel safety inputs, supports supervised reset/test input (ensuring downstream contactors or valves have dropped before restart), and can function as a stand‑alone safety relay or as an output‑expansion relay. Its compact width (22.5 mm) and DIN‑rail mounting make it suitable for installation in control cabinets, and front‑panel LEDs provide status indication (supply, relay, and output status). Delay for output drop (soft‑stop) is configurable between 0 and 1.5 s, enabling controlled shutdowns when required.

The ABB 2TLA020052R1000 — also known as Vital 1 — is a compact safety controller / safety relay module. It is designed to monitor safety devices (such as light‑curtains, safety switches/interlocks, emergency‑stop devices, safety gates/doors, etc.) using a single‑channel dynamic (“DYNlink”) safety circuit, and to provide safety‑rated relay outputs when the safety chain is closed. The module simplifies safety wiring by allowing up to ~30 compatible dynamic sensors in series, reducing the number of safety relays needed. It supports manual or automatic supervised reset, offers LED diagnostics (supply, sensor status, output status), and provides two safety relay outputs plus an auxiliary information output. The unit is DIN‑rail mountable and enclosed in a 22.5 mm‑wide compact housing — making it suitable for machine safety and control‑cabinet installations.

The 2TLA010002R0000 (JSBR4 24 VDC) is a universal safety relay designed to support two‑hand control devices and a variety of safety‑device inputs (e.g. emergency‑stop buttons, safety mats/edges, interlocks, safety switches, enabling devices). It provides supervised safety output switching — meaning that only when both safety inputs are properly actuated (e.g. two‑hand buttons pressed) and the reset/test input (if used) is satisfied, the safety outputs will close. The relay is DIN‑rail mountable, uses screw‑terminal connections, and includes LED indicators for supply, input, and output status. It is suitable for safety‑relevant applications requiring reliable, redundant control of safety outputs.

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.
