Safety relays
The MSI-MD-FB is a Muting interface designed for use in safety applications that require the temporary bypassing of protective fields (muting). It is classified under the Safety relays product category,.
Description and Explanation
The MSI-MD-FB acts as an interface specifically for muting applications, working in combination with standard variants of MLC and ELC safety light curtains, as well as MLD multiple light beam safety devices,.
This muting interface is certified to the highest safety levels: Performance Level (PL) e and Category 4 in accordance with EN ISO 13849-1, and SIL 3 according to IEC 61508,.
The device supports various advanced muting functionalities,:
- Sequence controlled 2-sensor muting or 4-sensor muting,.
- Timing controlled 2-sensor muting,.
- It also features a Muting enable function and a Muting-timeout extension,.
- Restart functionality is available in both Automatic and Manual modes,.
