      PRODUCT & ORDER FAQS

      Questions buyers ask about 1791D-OB16P

      • How is the output topology of the 1791D-OB16P configured and what electrical characteristics define it?

        The 1791D-OB16P provides sixteen sourcing output channels arranged in two groups of eight. Each channel supports an on-state voltage range of 10–30 V DC with a maximum on-state current of 0.5 A, and the entire module can deliver up to 4.0 A total load current.

      • What DeviceNet communication capabilities does the 1791D-OB16P support for distributed I/O systems?

        The 1791D-OB16P supports standard DeviceNet communication rates of 125 kbps, 250 kbps, and 500 kbps over both thick and flat media, enabling robust integration with ControlLogix, SLC, PLC-5, and other Rockwell Automation controllers that include DeviceNet scanners.

      • What integral status diagnostics are provided by the 1791D-OB16P for monitoring module and network health?

        The 1791D-OB16P incorporates multiple LED indicators to show Module/Network status (red/green), Logic status (green), and I/O activity (yellow), enabling rapid visual verification of communication integrity and output performance during commissioning and maintenance.

      • What overload and transient behavior specifications characterize the 1791D-OB16P outputs?

        Each output channel on the 1791D-OB16P withstands a surge current up to 1.0 A for 10 ms, repeatable every 2 seconds, facilitating reliable transient response for inductive loads and short-duration current spikes typically found in industrial actuation circuits.

      • What environmental and enclosure standards apply to the 1791D-OB16P for industrial facility deployment?

        The 1791D-OB16P is designed to meet IEC IP20 enclosure standards and operate within industrial ambient conditions, making it well-suited for protected control cabinets where discrete outputs must withstand mechanical and electrical stress.

      • What power supply considerations must be addressed when integrating the 1791D-OB16P into a DeviceNet segment?

        The 1791D-OB16P requires DeviceNet power within the range of 11 V to 25 V DC and typically draws up to 200 mA (with expansion modules attached), so ensuring adequate supply and network trunk power capacity is essential to avoid under-voltage conditions.
