BDL-498153983 / A6
Functional description
This module allows the connection of an LSN loop with up to 254 LSN
improved
elements with a
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!
