Siemens 3TK2842-2BB41 Safety Relay

The safety relay, also known as safety module or safety control, with type number 3TK2842-2BB41 from Siemens is an electrical relay for monitoring safety functions in industrial systems. It features electronic enabling circuits (FK) and is operated with a direct current voltage of 24 V. Connection is made via 22.5 mm spring-cage terminals. It offers an instantaneous enabling circuit (1 HL) and a delayed enabling circuit (1 HL) with an adjustable delay time from 0.05 to 3 seconds. The device supports AUTOSTART or a monitored start and meets high safety requirements with a maximum achievable SIL of 3 and Performance Level (PL) e. It has the dimensions 15 x 5 x 15 cm and weighs 0.15 kg. Safety relays are used to protect machines and systems from dangerous conditions by monitoring emergency stop functions, protective doors, and light curtains, and safely shutting them down when necessary. Typical applications include mechanical engineering for safeguarding production lines and in automation technology for implementing safety-oriented controls.
