The Siemens 6ES7222-1HF00-0XA0 is the EM 222 expansion module that adds 8 relay outputs to a SIMATIC S7-200 base unit — but only to the S7-21X CPU family, not the later 22X series. Each output is rated 2 A, optically isolated from the backplane, so a short on one field circuit won't take down the CPU or adjacent channels.
This module connects to the expansion bus of an S7-21X CPU.
Yes, the EM 222 8 relay output module is designed for the S7-21X CPU family, which includes the CPU 222. It connects directly to the expansion bus on the side of the CPU.
It provides 8 relay outputs, each rated 2 A, with optical isolation between the field side and the backplane. The relay contacts switch the load directly — no external interposing relay needed for most solenoid and indicator loads.
