Product Description
SIEMENS · SIMATIC S7-300 · SM 322
6ES7322-1HH01-0AA0
Digital output module with 16 relay outputs, electrically isolated in groups of 8, for switching AC/DC loads within the specified operating range of the SIMATIC S7-300 system.
Module Context
Relay switching in an S7-300 installation
The module is specified for switching direct- and alternating-current loads. Siemens documentation lists applications including solenoid valves, contactors, motor starters, small motors and signal lamps, subject to the stated electrical limits.Siemens 6ES7322-1HH01-0AA0 was phased out under product phase-out PM400, effective from October 1, 2023.

Installation and operating limitations
- For horizontal installation, the load must be limited so that two adjacent outputs do not exceed the permitted load.
- For vertical installation, the load must be limited so that four adjacent outputs do not exceed the permitted load.
- Maximum aggregate output current per group is 8 A for horizontal installation up to 60 °C and for vertical installation up to 40 °C.
- Siemens specifies no diagnostic function, no diagnostic alarm, and no wire-break, short-circuit, fuse-blown or missing-load-voltage diagnostics for this module.
Application
Typical operating role
Used where relay-based switching is required for AC or DC field loads in the S7-300 environment, including actuator and signaling circuits covered by the manufacturer's specified limits.
Failure Search Trigger
When replacement is investigated
Common maintenance searches can begin when a commanded field load no longer switches as expected, an output circuit remains inactive, or an installed relay-output module requires replacement.
Downtime Risk
Affected process operation
Loss of a required switching channel can leave a connected actuator or signal circuit without the commanded state and may interrupt the affected machine or process.
Documentation
Check the exact article number
Before ordering, compare the article number and the manufacturer's technical documentation with the installed module and application requirements.
