Panel fit and switching limits
The 6ED1052-1FB00-0BA8: The unit mounts on 35 mm DIN rail and occupies 4 spacing units (71.5 mm wide), with a depth of 60 mm and height of 90 mm. The display is included, so no separate programming panel is needed for on-site diagnostics or parameter tweaks.
How it compares to the wider sibling (0BA7)
If you are cross-referencing 6ED1052-1FB00-0BA7, note that this 0BA8 is narrower (4 SU vs 6 SU) but slightly deeper (60 mm vs 55 mm). The electrical specs are identical—same supply range, same 8 DI / 4 DO relay outputs, same 10 A resistive / 3 A inductive limits. The power reserve matches at 480 h. The footprint difference is the only layout consideration; rewiring is not required because the I/O count and screw-terminal positions follow the same LOGO! 8 pattern. Separately, the 6ED1052-1FB00-0BA6 is the same 4 SU width but carries only 80 h of power reserve—this 0BA8 holds six times longer at 480 h. If your application logs data over power outages or requires retained program state across multi-day downtime, the 0BA8 is the clear choice.
Lifecycle and certifications
For compliance documentation, expect UL/CSA nameplate markings and a CE declaration of conformity. That covers most panel builders' file requirements for a small controls controller.
Integration notes
Onboard Ethernet with web server and data logging is standard. The memory holds 400 function blocks, expandable via microSD card. Programming requires LOGO! Soft Comfort V8 or higher; existing projects from earlier LOGO! generations can be migrated. External fusing is required on the outputs—no internal short-circuit protection.
