Opto 22 SNAP D Series Racks Data Sheet
The SNAP D Series racks are designed for discrete control applications and can accommodate 4, 6, 8, or 12 SNAP 4‑channel digital modules. All models use an industry‑standard 50‑pin header connector and offer both panel mounting and DIN‑rail mounting options. The racks draw power from a single 5 VDC source and include optional auxiliary terminal strips for additional wiring.
Dimensions vary by model, with overall lengths ranging from 4.19 in (106.43 mm) for the SNAP‑D4M to 10.74 in (272.8 mm) for the SNAP‑D12M. Power consumption increases with module count, from a maximum of 200 mA for the 4‑module rack to 1.2 A for the 12‑module rack. Detailed pinout diagrams, terminal strip usage, and mounting guidelines are provided throughout the sheet.
