Bosch LSN 1500 A Manuel D'installation page 14

English
Functional description
This module allows the connection of an LSN loop with up to 254 LSN
maximum line current of 1500 mA or with up to 127 standard LSN elements, with a maximum line
current of 300 mA.
It can only be plugged in on the left side of a PRD 0004 A panel rail and requires two slots!
