Siemens 3TK2845-1DB40 SIRIUS Safety Relay - Discontinued
Siemens SIRIUS safety relay with relay and electronic enabling circuits.
The Siemens 3TK2845-1DB40 is a SIRIUS safety relay with relay and electronic enabling circuits, operating on 24V DC with a 45mm width and screw terminals. It features 4 normally open (NO) enabling circuits (EC) and one signaling contact (SC). This basic device supports monitored start-up and achieves maximum PL of e and SIL of 3. Please note: This product is phased out, with the 3SK2 series being its successor.
This safety relay was used in applications requiring multiple enabling circuits for comprehensive machine safety monitoring. Its discontinuation indicates the availability of more advanced solutions, but it may still be found in existing installations in sectors like automotive, general manufacturing, and material handling.
