DM8 12/24 expansion module, order code 6AG1055-1PB00-2BY0, 4 digital inputs and 4 transistor outputs at 0.3 A, 24 V DC supply, -40 to +70 °C operating with conformal coating.","salesMarkdown":"## What lands in the panel The Siemens 6AG1055-1PB00-2BY0 is a SIPLUS LOGO! DM8 12/24 digital expansion module, carrying four digital inputs and four transistor outputs on a 24 V DC supply. It drops onto the LOGO! 8 expansion bus and lives on a 35 mm DIN rail, 36 mm wide (2 DU), 90 mm tall, 55 mm deep, with an IP20 rating for cabinet-mounted service. ## Thermal envelope and where it can be installed Above +2 000 m the curve steps down, with allowances layered against the published barometric pressure bands up to +5 000 m. ## Switching budget on the four transistor outputs Each transistor output is rated 0.3 A at the \"signal 1\" level; above 55 °C that drops to 0.2 A steady, with 0.3 A allowed only for pulses under 15 s. Output short-circuit protection is built in, so a miswired field cable trips the channel rather than the upstream supply. ## Supply window and EMC posture EMC Class B compliance permits installation in residential areas without extra filtering. ## Approvals on record UL approval is on file under File E120869 with Tmax = 55 °C; FM, CSA, and marine approvals are not carried on this variant. ## RFQ posture Spec the 6AG1055-1PB00-2BY0 into the BOM line against the 0.3 A steady (0.2 A above 55 °C) transistor budget and the 55 °C UL ceiling; both ratings are the ones that decide fit. Send the RFQ for quoted lead time and condition on the order code exactly as printed.","metaTitle":"6AG1055-1PB00-2BY0 SIPLUS LOGO! DM8 12/24, 4DI/4DO","metaDescription":"SIPLUS LOGO!
