Siemens LOGO! DM8 12/24R Expansion Module 6ED1055-1MB00-0BA2

6ED1055-1MB00-0BA2 Overview

The LOGO! DM8 12/24R (6ED1055-1MB00-0BA2) is the dual-voltage input variant of the digital expansion modules for the Siemens LOGO! 8 logic platform. Its 8 digital inputs accept both 12 VDC and 24 VDC signals, which accommodates legacy 12 V installations and mixed-voltage control panels that would otherwise need interposing relays. The 4 relay outputs switch up to 10 A, enough for contactors, solenoid valves and small motor starters. Like the whole DM8 series, the module attaches to the LOGO! system bus, is programmed together with the base unit in LOGO! Soft Comfort, and mounts on a 35 mm DIN rail in the compact LOGO! housing. It is a practical service part wherever LOGO! 8 systems in building services, water treatment or light industry need additional inputs at low voltage levels.

Why Choose Siemens Logic Module Technology?
