Product Details:

NI PC-DIO-96/PNP is an ISA-bus digital output board derived from the PC-DIO-96 series, designed for industrial parallel pattern control and relay driving tasks, and this isa digital output board features PNP sourcing output channels to directly supply current to external loads. It differs from the standard bidirectional TTL version, focusing on reliable pnp sourcing digital drive for solenoids, indicator lamps, optocouplers and relay coils. It is widely used for fixture control in electronic functional testing, production sequence switching, lighting array control, old automated assembly stations, educational logic test platforms and legacy equipment retrofitting. Programmers can operate the hardware with LabVIEW, LabWindows/CVI and legacy NI-DAQ drivers, and register-level programming is available for custom timing, which supports stable parallel pattern output on older industrial computers with ISA slots.

Key specifications and parameters: 96 PNP sourcing output channels, grouped into 12 separate 8-bit ports. Each channel can source current to external loads, with compatible logic level for 5 V to 24 V field circuits. It is controlled by onboard 8255A PPI chips, supporting port-wise output configuration and strobe handshake signals. An integrated 8253 timer with 2 MHz reference clock provides periodic interrupt trigger signals for timed output sequences. The external signal interface adopts a 100-pin ribbon connector for connection to terminal blocks and relay accessories. The board is powered from the ISA slot +5 V rail, and the load power for PNP channels needs to be supplied separately. It is non plug-and-play ISA hardware, requiring manual jumper setup for base address and IRQ resources. Output logic is compatible with common positive logic industrial circuits. The operating temperature range is 0 ℃ to 70 ℃, storage temperature -55 ℃ to 150 ℃, humidity 5%–90% non-condensing. It is software-timed, suited for static pattern output and low-speed sequence control.

This high density parallel pattern output board is an end-of-life legacy NI hardware. We supply fully inspected and tested refurbished units for replacement and maintenance of old test benches and industrial control systems. It can be matched with signal conditioning modules and relay terminal assemblies to expand load capacity. It is widely adopted in electronics manufacturing test fixtures, university automation teaching labs, packaging equipment renovation and legacy ATE platforms. As a dedicated PNP sourcing digital board, it delivers stable parallel switching control for long-running legacy measurement and control projects.
