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. ## Compatibility and fit This module connects to the expansion bus of an S7-21X CPU.","metaTitle":"Siemens 6ES7222-1HF00-0XA0 EM 222 8 Relay Output Module","metaDescription":"SIMATIC S7-200 EM 222 digital output module, 8 relay outputs at 2 A each, optically isolated.
