The BMXAMO0802H: The module draws its power from the rack backplane (150 mA at 3.3 V DC and 135 mA at 24 V DC), with typical consumption of 3.6 W at 24 V DC. Isolation is rated at 1400 V DC between channels and ground, and between channels and bus; channels are non-isolated from each other.
Severe Environment and Compliance
Gas resistant class Gx and 3C4, dust and sand resistant class 3S4, salt level 2, mold and fungus resistant class 3B2. Conformal coating and Class I Division 2 rating. The module complies with IEC 61131-2, IEC 61000-6-4 (emission), IEC 61000-6-2 (immunity), and EN 61010-2-201. It operates from -25 to 70 °C ambient, with storage down to -40 °C. Relative humidity range is 5–95% at 55 °C without condensation. Operating altitude is up to 2000 m (derating to 5000 m). Shock resistance is 30 gn, vibration resistance 3 gn.
Output Characteristics and Diagnostics
Each of the eight outputs has a load impedance limit of 350 Ω for the 4-20 mA range. Maximum conversion value extends to 21 mA for both ranges. The module detects open circuit on the 4-20 mA range and short circuit on the 0-20 mA range. Fallback mode is configurable to predefined values.
