Each group connects via the 20-pin front connector, and the relay contacts are optically isolated from the backplane bus — meaning a short on one output group won't drag down the CPU or the other group. ## Lifecycle status: eol_hot ## What the relay outputs mean for your panel The 16 relay outputs are rated for AC and DC loads per the contact rating. The two isolated groups allow mixing load voltages on the same module. The 20-pin front connector matches the standard S7-300 wiring scheme; the module snaps onto the DIN rail in the same footprint as any SM 322.","metaTitle":"Siemens 6ES7322-1HH00-0AA0 SM 322, 16 Relay DO, EOL","metaDescription":"Siemens S7-300 SM 322 digital output module, 16 relay outputs (2x8), 20-pin.
