Product details

The Siemens 6ED1055-1FB00-0BA0 LOGO! DM8 230R is an expansion module adding four digital inputs and four relay outputs to a LOGO! base unit, with a thermal continuous current of 10 A per relay and 20 A total across all four relays. It accepts AC/DC supply in the 85–253 V DC or 47–63 Hz AC range (115–230 V nominal), and the inputs interpret signal "1" above 79 V AC, signal "0" below 40 V AC. Rated for resistive load switching at 2 Hz and inductive loads at 0.5 Hz; mechanical switching frequency up to 10 Hz.

Panel fit and approvals

Carries CE, UL, CSA, FM, and marine approvals; limit class B for residential-area use.
