Installation Notes

Verify the board’s actual function and pinout against the INFI 90 cabinet drawing before installation — do not rely on conflicting market listings.
De-energize the INFI 90 power system before inserting or removing the board from its slot.

After installation, verify module status via the INFI 90 diagnostics / operator station before returning the loop to service.

Common Questions

Is 660-MISC-3311 the same part? Multiple different Bailey part numbers (6637517A1, 6637804CI, 6637849E1, IMDS001) have been associated with “660-MISC-3311” by different dealers, so the 660-MISC-3311 reference itself is unreliable as a unique identifier and should not be used alone for ordering.

Can this board be ordered as a “digital input module”? Only if confirmed by documentation. The “16-channel digital input” description appears in low-credibility listings only and conflicts with other listings; ordering it as a DI module without verification risks receiving a wrong part.
