Description

The GE-Emerson IC693ALG223 16-Channel Analog Current Input Module provides up to 16 single-ended input channels, each capable of converting an analog input signal to a digital value for use as required by relevant applications. The module provides three input ranges: 4 to 20mA, 0 to 20mA, and 4 to 20mA Enhanced.

The default range is 4 to 20mA with user data scaled so that 4mA corresponds to a count of 0 and 20mA corresponds to a count of 32,000. The other ranges are selected by changing the configuration parameters using the IC641 configurator software or the Hand-Held Programmer. The range can be configured so that the input range is 0 to 20mA with user data scaled so that 0 mA corresponds to a count of 0, and 20mA corresponds to a count of 32,000.  Full 12-bit resolution is available over the 4 to 20 and 0 to 20mA ranges.

A 4 to 20mA Enhanced range can also be selected.  When this range is selected, 0mA corresponds to a count of –8,000, 4mA corresponds to a count of 0 (zero) and 20mA corresponds to a count of 32,000.  The Enhanced range uses the same hardware as the 0 to 20mA range but automatically provides 4 to 20mA range scaling with the exception that negative digital values are provided to the user for input current levels between 4mA and 0mA.  This gives you the capability of selecting a low alarm limit that detects when the input current falls from 4mA to 0mA, which provides for open-wire fault detection in 4 to 20mA applications.  High and Low alarm limits are available on all ranges.  Ranges can be configured on a per channel basis.  The module also reports module status and user-side supply status to the CPU.
