TETHYS IP65 SR - Safety Relay

The TETHYS IP65 SR is a universally applicable safety relay with three safe relay contacts. It ensures that the moving parts of a machine are switched off quickly and safely in the event of danger. Can be used up to PL e, SIL 3, category 4.
The waterproof and dustproof housing in accordance with protection class IP65 enables operation outside control cabinets, e.g. directly on the machine. This makes the TETHYS IP65 SR perfect for decentralised and demanding applications.
In addition, the TETHYS IP65 SR is certified for use in combustion plants in accordance with EN 50156-1 and EN ISO 13577-4 .
