2️⃣Core Features

24-channel contact acquisition with per-point LED and hysteresis
1500 V opto-isolation per channel to logic side
Adaptive wetting-voltage threshold + under-voltage annunciation
Automatic 4 s optocoupler continuity self-test
Dual IONet ports for redundant controller fabric
Direct mount on Mark VIeS terminal board via DC-37; no ribbon cable
Simplex / dual / TMR voting done in controller, pack is stateless I/O endpoint
S-conformal coating for turbine-hut / offshore environments

3️⃣Typical Applications

Gas / steam turbine permissive & trip contact input (lube oil, overspeed, flame, breaker aux)
Mark VIeS safety shutdown logic (SIS layer of turbine protection)
Compressor train interlock acquisition
Hydro governor gate-position contacts
Retrofit of Mark V → Mark VIe I/O packs where STCI/TBCI boards retained
