Features:
- Combines eight isolated digital inputs and eight protected digital outputs on one M7 submodule.
- Generates process interrupts from a configured rising or falling input edge.
- Allows 750 microsecond or 3 millisecond input filtering to balance response and cable length.
This order number is the IF 961-DIO binary interface for SIMATIC M7, identified as submodule 02H.
It couples 24 V field states and compact actuator commands directly to the automation computer.
Carrier type, connector wiring, filtering choice and output load category must be checked against the saved M7 project.

- M7 machine controllers use the input pairs for isolated limit and interlock signals while driving small indication or relay loads.
- Test systems can trigger software processing from a selected transition instead of continuously polling every channel.
- Retrofit cabinets use the card where a mixed 8-input and 8-output interface must remain within one M7 submodule position.
- Each input can be configured to create an interrupt on either the rising or falling signal edge.
- Output short circuits are handled electronically to protect the channel electronics.
- Input grouping isolates pairs so process potentials can be organised across four channel sections.
- Field wiring terminates through the documented 25-pin D-sub assignment.
- Shielded cable can extend to 1000 m, while unshielded limits depend on the selected input delay.
- The carrier must provide the correct M7-300 24 V or M7-400 5 V submodule supply.
- The system identifies the submodule by code 02H during hardware setup.
- Input filtering is selectable between 750 microseconds and 3 milliseconds.
- Interrupt enable and edge polarity are set independently for the required process response.
