Ruggedness and environmental rating
The BMXDDI6402KH: Conformal coated as standard, with resistance to gas (class 3C4), dust (3S4), salt (level 2), mold (class 3B2), and fungal spores. Rated for operation from -25 to 70 °C and 0 to 2000 m altitude (derated to 5000 m). This means the module is intended for severe industrial environments — not just a clean cabinet.
Input characteristics and isolation
Voltage state 1 guaranteed above 15 V; state 0 below 5 V (inferred from typical thresholds). Channel-to-bus isolation is 1500 V for 1 minute, and dielectric strength between groups reaches 1500 V AC primary/secondary. Response time is 4 ms typical, 7 ms maximum — suitable for most discrete sensing with mechanical contacts or standard proximity switches.
Compliance and certifications
Carries CE, UKCA, cULus, RCM, and EAC markings. Conforms to IEC 61131‑2 and the LV/EMC directives (2014/35/EU and 2014/30/EU). The module is IP20 protected.
