Netstal 100.240.7771 Sycap CPU 286 Board DiskJet Injection Molder 600/110

Netstal 100.240.7771 Sycap CPU 286 Board DiskJet Injection Molder 600/110

This is the Netstal Sycap CPU 286 PRINT V controller board, part number 100.240.7771, designed for use in the Netstal Sycap Temp Controller system fitted to the DiskJet (Discjet) 600/110 Injection Molder. It is a card-edge expansion board built around an Intel 80286-class CPU and is the central processing unit of the Sycap temperature control subsystem within that machine. The board was pulled directly from a Netstal Discjet 600/110 Injection Molder that was in working operation.

Applications

The Netstal Sycap system was Netstal's proprietary supervisory control and data acquisition platform used in their DiskJet/Discjet series injection molding machines, which were widely used from the late 1980s through the 1990s for high-speed precision molding of optical discs and other small plastic components. The CPU 286 board serves as the main processing card within the Sycap temperature controller, handling process control logic, keyboard input (P5/W807), and printer output (P6/W800) for the machine's control subsystem. Facilities still running Netstal Discjet 600/110 systems — or those performing restorations — often need these CPU boards as direct replacements when the control system fails, since the Sycap architecture is proprietary and OEM boards are no longer manufactured. This board is the correct replacement for any system accepting part numbers in the 100.240.7771 / 110.240.7771 family.
