For inductive loads, the rating drops to 3 A at 230 V DC and 2 A at 24 V AC — a key derating to account for when switching solenoids, contactors, or motor starters. The relay contacts are rated for 300,000 mechanical cycles at low load, but this drops to 100,000 cycles at 230 V AC, 3 A. That mechanical endurance figure sets the service life in high-cycle applications like pick-and-place or packaging lines. Short-circuit protection is not built in and must be provided externally — a per-channel fuse or circuit breaker is required in the field wiring, which is standard practice for relay output modules in a control panel. ## Integration with S7-300 The module fits a standard S7-300 DIN rail slot with a 40 mm width and 125 mm height, requiring a 40-pin front connector for field wiring. It draws a maximum of 40 mA from the 5 V DC backplane bus and 125 mA from the 24 V DC load supply L+. Unshielded cable runs up to 600 m are supported for the digital outputs, and shielded runs up to 1,000 m. The module does not include diagnostic alarms, wire-break detection, or fuse monitoring — so fault finding relies on the external protection and PLC logic.","metaTitle":"Siemens 6ES7322-1HF10-0AA0 SM322 Digital Output Module","metaDescription":"Siemens SM322 digital output module 6ES7322-1HF10-0AA0 with 8 relay outputs.
