Siemens 6ED1055-1FB00-0BA2 Simatic Logic Module

Siemens 6ED1055-1FB00-0BA2 is the LOGO! DM8 230R expansion module designed to extend a LOGO! 8 controller’s I/O with four digital inputs and four relay outputs. This expansion lets you sense external signals and switch loads directly through relays, with all four outputs rated at 5 A (the DM8 230R variant). Built for compact automation, it integrates into the LOGO! ecosystem to support small-to-mid-sized tasks such as lighting control, pump or valve actuation, and simple conveyor or automation sequences. The 6ED1055-1FB00-0BA2 part number identifies the DM8 230R expansion, a widely listed accessory from Siemens and distributors for enhancing LOGO! 8 systems without adding a full PLC. The module is intended for use alongside LOGO! 8 base units, delivering scalable, space-efficient control in a compact package.
