The 6AG10521FB087BA1: 8 relay outputs rated via the CPU's integrated DO. Each relay handles up to 3 A inductive / 10 A resistive (per the sibling 6AG1052-1FB08-7BA1 specification – same relay driver). The 12 W power draw is the entire CPU; at 24 V that's 0.5 A from your panel supply. No display means no operator panel on the unit – you'll need an HMI for local interaction.

Frequently asked questions
When sourcing 6AG10521FB087BA1, what's the closest functional sibling?
6AG1052-1FB08-7BA1 has the same I/O count and physical width but includes a display and wider temperature range (-40 to +70 °C). It is not a direct mechanical swap if your panel lacks a display cutout.
Will 6AG10521FB087BA1 drop into a panel designed for 6AG1052-1FB08-7BA1?
Mechanically yes – both are 4 spacing units wide on 35 mm DIN rail – but without the display opening you lose nothing if the panel has no cutout. If the panel has a display cutout, this CPU will leave a gap.
