Product details

Listed as a current spare part for existing S7-200 CN systems. This is not a forward-design component; source it to maintain installed machines or fill a committed BOM. No official successor is recorded, so the path is to procure directly from Siemens spare channels or through the independent distributor network. Expect quoted lead times at time of RFQ.

The module is 71.2 mm wide, 62 mm deep, and 80 mm tall. It connects to the S7-200 CN rack and provides 4 differential analog inputs with ±10 V range.

Frequently asked questions

Will 6ES7235-0KD22-0XA8 drop into a panel specified around 6ES7222-1BF22-0XA0?

Not without widening the slot. This module is 71.2 mm wide; the 6ES7222-1BF22-0XA0 is 45 mm wide. Height and depth match (80 mm and 62 mm respectively), but the horizontal footprint is different.

What compliance markings does this module carry?

Only CE approval is stated on the documentation. No UL, CSA, or RoHS/REACH declarations appear in the spec record. Verify additional certifications with the Siemens spare parts channel before ordering for projects requiring those marks.
