Profinet / EtherNet-IP Industrial Control Integration
The 1794-OB16PXT operates as a FLEX I/O discrete output module connected through the FLEX I/O adapter and backplane communication structure. The module transfers output command data from the controller network to field-level switching circuits. The 16 output points provide sourcing DC operation with electronic protection for connected loads. The module supports I/O density scaling within the FLEX I/O 1794 platform by adding compact discrete output channels in distributed control installations.
Frequently Asked Questions
Q: Is the 1794-OB16PXT output module isolated between channels?
A: No. The module provides 16 non-isolated sourcing DC output channels. Field wiring separation and external protection must be considered according to application requirements.
Q: What is the maximum output current capability of each channel?
A: Each output channel supports 1.0 mA minimum on-state current and up to 500 mA maximum current.
Q: Can the module be installed in a hot-swap configuration?
A: The provided data does not specify hot-swap limitations. Installation and removal procedures should follow the FLEX I/O system hardware documentation and applicable electrical isolation requirements.
Field Installation Guidelines
- Install the module on the designated FLEX I/O terminal base and DIN rail mounting structure.
- Verify that field power wiring matches the 10 VDC to 31.2 VDC output voltage range.
- Use appropriate conductor routing to separate DC output wiring from high-voltage or high-noise circuits.
- Connect cable shields according to the grounding practices defined for the control cabinet and system design.
- Confirm output load current does not exceed the 500 mA per channel limit.
- Verify terminal connections and module seating before applying field power.
- Maintain cabinet airflow requirements to prevent operation outside the specified -20 to +70 deg C temperature range.
