The display version adds a backlit LCD and four analog-capable inputs, while this module has no display and no analog inputs – pure digital I/O. Mounting and relay ratings are identical. Power supply is the same 24V AC/DC range on both. So swapping into a panel designed for that sibling is physically and electrically fine – the only change is losing the display/analog input feature. For many OEM applications, that's a welcome trade-off.

Frequently asked questions
What's the closest functional second-source if I can't get this exact code?
The 6ED1052-1MD00-0BA6 is the nearest sibling. It adds a display and four analog-capable inputs but runs on the same 24V supply and shares the same footprint and relay ratings. If your application doesn't need display or analog, you can drop it in physically – just note the added front height from the display.
Will 6ED1052-2HB00-0BA2 drop into a panel specified around 6ED1052-1MD00-0BA6 without rewiring?
Yes. Both mount on 35mm DIN rail at 4TE width. The terminal assignments are identical for the 8 inputs and 4 relay outputs, and both accept 24V AC/DC. The only functional difference is the lack of a display and analog inputs on this unit – no wiring changes needed.
