32 inputs at 48 VDC sink — immediate fit for high-density I/O banks
BMXDDI3203H packs 32 current-sink inputs at 48 VDC into a 32 mm wide housing — three modules fill a standard 100 mm DIN section. Hot-swap capable, so you can pull and replace without cycling the rack power. Typical response time is 4 ms, maximum 7 ms — fast enough for most discrete sensing lines. Conformal coating and IP20 keep it running in condensing or dusty enclosures.
Panel fit and environment — what the ratings actually mean
Dimensions: 86 mm deep, 32 mm wide, 134.6 mm tall. Pollution degree 2 rated, so it lives in a standard IP54 cabinet without special gasketing. Vibration 3 gn, shock 30 gn — fine for machine-mounted arrays with typical isolation. Environmental qualification includes gas, dust, sand, salt, mold, and fungal spore resistance — enough to stand up to a chemical plant or offshore platform. Operating altitude 0–2000 m standard, derate to 5000 m if needed.
Sourcing and lifecycle — current production, no end-of-life pressure
MTBF reliability is 2500000 H.
Compliance and documentation — nameplate-ready for any project file
Marked CE, UKCA, CULus, RCM, EAC. Complies with IEC 61131-2, plus Low Voltage and EMC directives. Conformal coating and 1500 V isolation between channels and bus match the expectat data for industrial panels.
