GE IC693ALG223RR Analog Input, Current, 16 Single Channels

The 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 your application. 

This module provides three input ranges:

 4 to 20 mA

 0 to 20 mA

 4 to 20 mA Enhanced

Current Ranges

The default range is 4 to 20 mA with user data scaled so that 4 mA corresponds to a count of 0 and 

20 mA corresponds to a count of 32000. 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 20 mA with user data scaled so

that 0 mA corresponds to a count of 0 and 20 mA corresponds to a count of 32000.

Full 12-bit resolution is available over the 4 to 20 and 0 to 20 mA ranges.

A 4 to 20 mA Enhanced range can also be selected. When this range is selected, 

0 mA corresponds to a count of –8000, 4 mA corresponds to a count of 0 (zero) and 20 mA corresponds to a count of +32000. 

The Enhanced range uses the same hardware as the 0 to 20 mA range but automatically provides 

4 to 20 mA range scaling with the exception that negative digital values are provided to the user for input current levels between 4 mA and 0 mA. 

This gives you the capability of selecting a low alarm limit that detects when the input current falls from 4 mA to 0 mA, 

which provides for open-wire fault detection in 4 to 20 mA 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.

Power Requirements and LEDs

This module consumes 120 mA from the 5V bus on the PLC backplane and also requires 65 mA plus 

current loop current(s) from a user supplied +24V supply (see Table 3-13, Specifications).

There are two green LED indicators on the module which provide module and user supply status. 

The top LED, MODULE OK provides module status information on power-up as follows:

 ON: status is OK, module configured;

 OFF: no backplane power or software not running (watchdog timer timed out);

 Continuous rapid flashing: configuration data not received from CPU;

 Slow flashes, then OFF: failed power-up diagnostics or encountered code execution error.

The bottom LED, User Supply OK, indicates that the user provided 24V supply is within

specifications, thereby enabling the analog side of the module to work properly

This exceptional control solution is compact, cost-effective, and adaptable, serving as a compact PLC, distributed

I/O, or distributed control system. 

We have the same series of models in stock.
