Key Technical Features & Functional Benefits
The module boasts exceptional accuracy with an absolute accuracy error of ±0.125% of full scale and low linearity error across the operating current ranges (4-20 mA, 0-25 mA, and 0-20 mA). Its temperature drift is minimal at less than 0.0050% of full scale per °C, ensuring stable measurement performance in fluctuating industrial conditions. High common mode rejection (> -90 dB at 60 Hz) and electrical isolation of 1780 VAC between channels and the communication bus contribute to superior noise immunity and safety.
Operating over an ambient temperature range of 0 to 60°C and capable of storage from -40 to 85°C, the 140ACI04000 adapts well to harsh industrial environments. It consumes a modest 5 watts of power and supports altitudes up to 5000 meters, allowing deployment in diverse geographic locations including high-altitude installations. The module’s reliable protection against broken wires within the 4-20 mA range helps maintain system consistency and avoid false readings due to wiring faults.
