8 DI / 8 DO relay mix for LOGO! expansion
The Siemens 6ED1055-1NB10-0BA0 is a LOGO! DM16 24R expansion module that adds 8 digital inputs and 8 relay outputs to a LOGO! base unit, running on a 24 V DC supply (20.4 V to 28.8 V permissible range).
Input thresholds and relay output capacity
Digital inputs see a signal "1" above 12 V DC, drawing a typical 2 mA per channel; signal "0" is below 5 V DC with a maximum permissible quiescent current of 1 mA. The relay outputs handle up to 5 A resistive load and 3 A inductive load, with a maximum lamp load of 1,000 W. Switching times are 1.5 ms max for both 0-to-1 and 1-to-0 transitions, and the mechanical relay life is rated at 10 Hz max cycling.
Approvals and compliance set
Carries UL, CSA, FM, and marine approvals, plus CE marking and VDE 0631 compliance — accepted across North American, European, and marine-class installations. Developed in accordance with IEC 61131 and rated limit class B for residential-area use, with IP20 protection on the enclosure.
