Bosch FLM-420-I8R1-S Eight-Input Relay Output Interface Module, Surface-Mounted

The FLM-420-I8R1-S is a two-wire LSN element that combines eight supervised inputs and one changeover relay output in a single enclosure. Each input is individually set according to line end resistance or contact supervision method; the relay output provides normally open contacts up to 2 A at 30 V DC and 0.5 A in alternating current. The 200 x 140 x 48 mm housing is used in locations where many signals are collected. Reducing eight points to a single address significantly reduces the loop's address budget.
