| Datasheet | Download Datasheet |
The Finder 7S.34.8.230.4220 is a 22.5 mm safety relay with 2A2B DPST-NO/DPST-NC contacts and rated 6 A, driven by a (230...240)VAC coil.
Its contacts are forcibly guided (mechanically linked) to EN 61810-3, so a normally open and a normally closed contact can never be closed at the same time. That is what lets a safety circuit detect a welded contact.
It is evaluated for functional safety applications to SIL 2 (EN 61508, EN 62061), PL d (EN ISO 13849-1).
It has DIN Rail mounting and box clamp terminals, contacts in AgSnO2 and is supplied with LED coil status indication.
