The Allen-Bradley 1797-IE8 Flex Ex analog input module is engineered for use in hazardous environments, featuring Intrinsically Safe inputs with certifications including Ex ia IIB/IIC T4 and AEx ia IIC T4. It offers eight individually configurable, non-isolated analog input channels that handle 0-20 mA and 4-20 mA signals with a 16-bit resolution, ensuring precise data conversion into digital formats with 0.1% accuracy at 20 °C and a temperature drift of 0.05% per degree Celsius. Boasting a rapid update rate ranging from 200 ms to 1600 µs, dependent on proximity to the communication adapter, this module integrates advanced internal diagnostics to identify alarms such as lead breakage and signal overrange/underrange, necessitating a compatible terminal base like the 1797-TB3 or 1797-TB3S for operation.
