Designed for integration in industrial settings, the Allen Bradley 1794-IE8 high-density analog module focuses on optimizing signal processing. It features eight single-ended inputs, allowing it to effectively capture data for various applications. The module exhibits a resolution of 12 bits for unipolar inputs and 11 bits plus sign for bipolar signals, which contributes to its versatility in measurements.
Operating at a conversion rate of 256 microseconds for all channels, this module ensures swift data acquisition. The nominal supply voltage required is 24 volts DC, with a permissible range from 19.2 to 31.2 volts DC. Furthermore, the module draws 60 milliamps of supply current at 24 volts DC, providing efficient power usage within the system.
A single green power indicator is included, providing a direct visual reference for the operational status of the module. With a maximum power dissipation of 3 watts at 31.2 volts DC and a thermal dissipation of 10.2 BTU/hr at the same voltage, this module maintains manageable heating under load. The isolation voltage reaches up to 850 volts DC, though individual channels do not feature isolation between them.
Additionally, the 1794-IE8 operates effectively in environments ranging from 0 to 55 degrees Celsius, accommodating various temperature conditions typical in industrial settings.
