R1.188.0450.1 Safety relay, SNZ 4052K, 24 V AC/DC

Basic unit, SNZ 4052K Function The device is fail-safe and self-monitoring. The synchronous operation of the two actuators (two-hand control switches or safety door contacts) is monitored. Both actuators are connected to the device with an NO and NC contact each. The technical design of the input circuity means there is cross-circuit and earth fault monitoring. The output function is designed with 2 NO contacts as enabling current path and 1 NC contact as signalling current path (all forcibly actuated). Applications - Protection of people or machines - Monitoring of two-hand devices - Safety gate monitoring - In accordance with EN 574 type IIIC - Up to category 4 (EN 954-1) Up to PL e (EN ISO 13849-1) Up to SIL cl 3 (EN 62061) Features - Stop category 0 according to EN 60204-1 - Two-channel activation 1 NO and 1 NC contact per channel - Cross-circuit detection - Monitoring of the synchronous actuation - 2 enabling current paths, 1 signalling current path - Screw terminals

The installation and commissioning must only be carried out by properly trained personnel. Viewing data sheet is essential.
