FLM-420-I8R1-S Octo-input interface module with relay
General Description
- The FLM‑420‑I8R1‑S Octo-input Interface Module with Relay allows the monitoring of up to eight inputs. Additionally, it features a change‑over contact relay for providing a potential‑free output contact. It is a 2‑wire LSN element. When connected to the fire panels FPA‑5000 and FPA‑1200, the interface module offers the enhanced functionality of LSN improved technology.
- Individually selectable monitoring functions (EOL or contact) for the eight inputs each
- Maximum switching capacity 2 A / 30 V DC or 0.5 A / 42.4 V AC
- Maintains LSN loop functions in the event of wire interruption or short-circuit thanks to two integrated isolators
- Easy wiring thanks to pluggable terminal blocks
