Siemens LOGO! DM8 12/24R Expansion Module 12/24V DC 4 DI / 4 Relay Outputs – 6ED1055-1MB00-0BA2

The Siemens LOGO! DM8 12/24R adds four digital inputs and four relay outputs to a LOGO! 8 logic module, and runs from either a 12 V or 24 V DC supply—which makes it the module of choice for battery-backed, solar and vehicle-based control panels where 12 V is the system voltage. Relay outputs switch up to 5 A resistive, driving contactors, solenoids and lamps directly. Features 4 digital inputs, 12/24 V DC 4 relay outputs rated 5 A resistive / 3 A inductive Wide 10.8–28.8 V DC supply range covers both 12 V and 24 V systems Only 35.5 mm wide (2 module widths) on 35 mm DIN rail Screw terminals for straightforward field wiring Suits LOGO! 8 and LOGO! 8.2 base modules Specifications Siemens order number 6ED1055-1MB00-0BA2 Product designation LOGO!
