The Allen-Bradley 5094-IB32 DC Digital Input Module requires a 24 Volts DC power supply for the left sensor actuator power terminals (+/-) in order to offer field-side power. It has a voltage category rating of 12/24 Volts DC and 32 input channels. The module has an on-state voltage range between 10 and 32 Volts, the minimum on-state current rating is 2 milliamps at 10 Volts, the nominal on-state current rating is 2.4 milliamps at 24 Volts, and the maximum on-state current rating is 2.6 milliamps at 32 Volts DC. It has a maximum off-state voltage rating of 5 Volts DC and a maximum off-state current rating of 1.5 milliamps. The 5094-IB32 DC Digital Input Module has a minimum input impedance rating of 3.8 kiloohms at 10 Volts, a nominal input impedance of 10 kiloohms at 24 Volts, and a maximum input impedance of 16 kiloohms at 32 Volts DC.

The Allen-Bradley 5094-IB32 DC Digital Input Module has an operating temperature range from -40 to +70 degrees Celsius according to the IEC 60068-2-1 standards for operating in cold environments, the IEC 60068-2-2 standards for operating with dry heat, and the IEC 60068-2-14 standards for operating with thermal shock. In addition to that, the storage temperature ranges between -40 and 85 degrees Celsius in accordance with the IEC 60068-2-1 standards when the module is stored unpackaged in a cold environment, the IEC 60068-2-2 standards when the module is stored unpackaged in dry heat, and the IEC 60068-2-14 standards when the module is stored unpackaged with thermal shock. The module has a maximum surrounding air temperature rating of 70 degrees Celsius and relative humidity range from 5 to 95 percent, non-condensing. It has a corrosive resistance rating of ISA S71.04 G2, which is for a non-extreme (non-XT) environment. It conforms to international standards such as the c-UL-us, CE, RCM, Ex, IECEx, KC, Morocco, and EAC standards.
