Module fit and electrical limits
The Siemens 6AG1055-1CB00-2XB0 is a SIPLUS variant of the LOGO! DM8 24, offering 4 digital inputs and 4 transistor outputs on a 24 V DC supply. It drops into the same DIN-rail footprint as the standard 6ED1055-1CB00-0BA0 but extends the ambient range to -25 to 70 °C (55 °C under UL listing). Outputs deliver 0.3 A per channel continuous up to 55 °C; above that limit, derate to 0.2 A continuous or allow 0.3 A for bursts under 15 s. If your loads are relays or indicators, headroom is fine; for solenoid banks, plan the derating.
DIN-rail footprint and approvals
UL listed to 55 °C per North American approval. Rated IP20.
