If you're maintaining or assembling semiconductor and PCB manufacturing equipment, the control board between your pneumatic valves and digital I/O can make or break your process stability. The Pneutronics 990-004366-001 D17-D24 Source, Sink D9-D16 board is built for that exact role, and its listed USD 279.95 price makes it a focused purchase for anyone who needs a dedicated process controller board.
Quick verdict
The Pneutronics 990-004366-001 is a single-unit process controller board aimed at semiconductor and PCB fabrication tools. The listing describes it as a D17-D24 source and D9-D16 sink board running on 24V DC and 100 psi. If your cabinet uses those signal levels and you need a board with this source/sink channel arrangement, the listed price is reasonable for a specialized replacement or spare.
Who it suits
This board is best suited for technicians and engineers who work on semiconductor or PCB manufacturing equipment and need a direct source/sink control board. Because it is specified at 24V DC and 100 psi, it is a natural match for pneumatic control circuits operating in that range. The board comes from Pneutronics and is made in the United States, which could be relevant if you keep track of where your spares come from.
The unit quantity is listed as one, so this purchase is an individual board. That makes sense if you already have a cabinet built around this model and simply need a replacement or a spare to keep on hand.
What stands out from the listed details
The most useful details are the electrical and pneumatic ratings: 24V DC and 100 psi. These two numbers define the board's role in your equipment, so confirming those values against your system is the first thing to do. The board is positioned as a process controller for semiconductor and PCB manufacturing, with power distribution as a key function. The source and sink arrangement in the title-D17-D24 source and D9-D16 sink-also gives you a concrete idea of how the channels are organized before you open the cabinet.
At USD 279.95, this board is a specific component rather than a generic breakout or interface. If you need exactly this voltage, pressure, and channel layout, the listing gives you the necessary identifiers to track down a matching board.
Meaningful trade-offs
Because the board is sold as a single unit at a USD 279.95 price, buying one for a multi-channel system means you will need one board per matching channel set. The board's operating specification is fixed at 24V DC and 100 psi, so it is not a general-purpose controller for other voltage or pressure ranges. Make sure those specs line up with your equipment before you commit.
The title focuses on the source/sink configuration and power ratings. For a maintenance engineer who already knows the harness, that is usually enough to work with. If you are building a new cabinet from scratch, your existing wiring diagram will be your best reference.
Pneutronics 990-004366-001 D17-D24 Source, Sink D9-D16 board
This board's main strength is that it is identified as a process controller for semiconductor and PCB manufacturing, with reliable power distribution as a central function. The country of origin is listed as the United States, and the board is offered as one unit. The main limitation is the specific 24V DC and 100 psi rating: if that does not match your pneumatic valves or I/O logic, this board is not a universal replacement.
Bottom line
For a technician who needs a Pneutronics source/sink board in the 24V DC, 100 psi range, the 990-004366-001 at USD 279.95 is a straightforward choice. It is a specialized component for a specific manufacturing context, and the listed electrical and pneumatic specs give you the information you need to decide before ordering.
