The ABB 2TLA010041R0600 — known as the Sentry BSR23 — is a safety‑expansion relay designed to increase the number of safe output contacts in a machine’s safety circuit when additional outputs are needed. It is intended to be used in conjunction with a main safety relay or safety PLC; it does not itself monitor safety inputs (emergency stops, light‑curtains, etc.), but provides additional failsafe relay outputs. The module is compact, DIN‑rail mountable, and uses screw‑terminal wiring, making it suitable for integration in control panels with limited space.

The ABB MPEP4‑10R is a modular emergency stop pushbutton designed for industrial safety applications. It features a red 40 mm mushroom head for easy activation and is non‑illuminated, making it suitable for emergency shutdown situations where rapid manual intervention is required. The device uses a pull release mechanism and does not include a contact block, allowing customization of its switching elements to fit specific control system requirements. This emergency stop is part of ABB’s modular pilot device range offering reliable performance and easy installation.
