Product Description
The Allen-Bradley 1794-IE4XOE2 is a Flex I/O combination module for distributed I/O architectures, featuring four single-ended, non-isolated analog inputs and two single-ended, non-isolated analog outputs. The inputs accept 0-20mA, 4-20mA, 0-10VDC, and +/-10VDC signals, converting them to 16-bit 2's complement data via a successive approximation ADC with a conversion rate of 256s. The outputs provide 0-20mA, 4-20mA, 0-10VDC, and +/-10VDC signals, generated by a pulse width modulation DAC. It requires a 1794-TB2, -TB3, -TB3S, -TB3T, or -TB3TS terminal base unit. Input resolution is 12 bits for unipolar and 11 bits for bipolar signals. The module operates on 24VDC, consumes 70mA, dissipates a maximum of 13.6 BTU/hour or 4 Watts, and measures 1.8 x 3.7 x 2.1 inches.
Is Your Device Showing These Signs?
The Allen Bradley 1794-IE4XOE2 FLEX I/O analog combination module commonly experiences issues related to calibration drift, resulting in inaccurate analog input/output readings. Field wiring terminations often loosen, causing intermittent signal loss and communication errors on the DeviceNet network. Component degradation, particularly electrolytic capacitor failure within the power supply circuitry, leads to module malfunction and requires component-level repair. Corrupted firmware necessitates reflashing to restore proper module operation and address software-related anomalies. Environmental factors, such as excessive heat or humidity, accelerate component aging and contribute to premature failure of the module.
