The Allen-Bradley 5094-IF8IH Analog HART Input Module has an input voltage range of 0 to 5 Volts, +/- 10 Volts, and 0 to 10 Volts. The input current ranges between 0 and 20 milliamps and 4 and 20 milliamps (HART). The module has an input impedance voltage rating greater than 1 megaohm and an input impedance current rating of 250 ohms and +/- 5 ohms (typical). It has a continuous channel to channel isolation rating of 250 Volts AC and a module conversion method that is the sigma-delta rating with a 24-bit Analog-to-Digital Converter (ADC) per channel. The 5094-IF8IH Module has an effective resolution current between 0 and 20 milliamps with 17 bits and between 4 and 20 milliamps with 17 bits at a frequency of 60 Hertz with a notch filter. It also has an effective resolution voltage of +/- 10 Volts with 17 bits, 0 to 10 Volts with 17 bits, and 0 to 5 Volts with 16 bits at a frequency of 60 Hertz with a notch filter.

The Allen-Bradley 5094-IF8IH Analog HART Input Module scan time both per channel and per module is 1.0 millisecond at a 10-kilohertz notch. The module has an onboard data alarming feature, an CIP sync feature, input timestamps, a feature for scaling to engineering units, and a real-time channel sampling feature. The 5094-IF8IH module has a backplane power (BP) voltage rating of 15 Volts DC and a maximum backplane power (BP) current rating of 35 milliamps. It has 2 calibration methods, that are the user-performed method and the factory calibrated method. The Analog HART input module has an operating temperature range between -40 and 158 degrees Fahrenheit and a maximum surrounding air temperature rating of 158 degrees Fahrenheit.
