The Siemens 6AG1222-1HH32-2XB0 is a SIPLUS variant of the S7-1200 digital output module, providing 16 relay outputs rated at 2 A each for resistive or inductive loads. It switches AC loads from 5 V to 250 V AC and DC loads from 5 V to 30 V DC. The extended temperature range of -40 to 70 °C, along with conformal coating typical of SIPLUS hardware, suits panels in cold storage, outdoor cabinet climates, or heat-soaked enclosures. Maintainter tip: coil draw is 11 mA from the 24 V load supply and 135 mA from the backplane 5 V bus—budget both when sizing the CPU power supply.
