Description
Category according to EN 13849-1
Due to two redundantly designed semiconductor outputs (safety outputs) with internal monitoring suitable for:
- Category 4/PL e according to EN 13849-1
Important: To achieve the stated category according to EN ISO 13849-1, both safety outputs (FO1A and FO1B) must be evaluated.
Key evaluation
EUCHNER products with FlexFunction require a teach-in operation during setup to configure the device. The device’s function depends on the taught-in key type.
Important: Keys must be ordered separately!
