Siemens 6AG1222-1HH32-4XB0 is a SIPLUS S7-1200 digital output module with 16 relay outputs, each rated 2 A for both resistive and inductive loads. Switching range covers 5 V to 250 V AC or 5 V to 30 V DC. Diagnostic alarm and channel status monitoring are standard. Operating temperature spans -40 °C to 70 °C — suited for unheated enclosures or process areas. Mounts on the S7-1200 rail; requires a front connector. No internal short-circuit protection, so external fusing per channel is needed. Draws 135 mA from the backplane bus plus 11 mA per relay coil.
