Features:
- Eight isolated outputs switch 48–125 V DC field loads.
- Two channel groups organize the field-supply and output connections.
- Electronic short-circuit protection supervises each output channel.
Siemens 6ES7322-1CF00-0AA0 converts S7-300 output data into eight high-voltage DC switching channels.
The two groups of four separate field wiring into defined common supply paths.
Channel LEDs indicate the commanded output state while field faults remain subject to wiring and load checks.
The Siemens 6ES7322-1CF00-0AA0 SIMATIC S7-300 SM 322 Digital Output Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Channel and Common Organization
- Channel count: Eight digital outputs are divided into two groups of four.
- Supply path: Each group uses its assigned field-load voltage connection.
- Output command: Individual channels follow the output image transferred from the S7-300 CPU.
- Front wiring: A 20-pin connector carries group supplies and switched channel conductors.
Current and Load Behaviour
- Rated channel: Each output switches the documented current within the specified 48–125 V DC load range.
- Resistive loads: Their lower stored energy permits the highest documented switching frequency.
- Inductive loads: Stored magnetic energy reduces the allowed switching frequency and requires suitable suppression.
- Lamp loads: Inrush behaviour sets a separate switching-frequency limit from resistive and inductive circuits.
Backplane and Field Separation
- Logic side: The S7-300 backplane supplies the module electronics and transfers output data.
- Field side: External load voltage supplies the two output groups and their connected devices.
- Isolation barrier: The field circuits are tested at the documented AC isolation voltage from the control side.
- Group boundary: The two four-channel groups keep their supply connections organized at the front connector.
Output State and Fault Checks
- Channel indication: Front LEDs show the commanded state of the individual outputs.
- Short circuit: Electronic protection responds when channel current exceeds the documented threshold.
- Field verification: An active LED does not replace checking the external voltage, wiring, and load.
- Cable distance: Shielded and unshielded field wiring use different documented maximum lengths.
