Notice:

OMRON products are manufactured for use according to proper procedures by a qualified operator
and only for the purposes described in this manual.

The following conventions are used to indicate and classify precautions in this manual. Always heed
the information provided with them. Failure to heed precautions can result in injury to people or dam­age to the product.

DANGER Indicates an imminently hazardous situation which, if not avoided, will result in death or

!

serious injury.

WARNING Indicates a potentially hazardous situation which, if not avoided, could result in death or

!

serious injury.

Caution Indicates a potentially hazardous situation which, if not avoided, may result in minor or

!

moderate injury, or property damage.

OMRON Product References

All OMRON products are capitalized in this manual. The word “Unit” is also capitalized when it refers
to an OMRON product, regardless of whether or not it appears in the proper name of the product.

The abbreviation “Ch,” which appears in some displays and on some OMRON products, often means
“word” and is abbreviated “Wd” in documentation in this sense.

The abbreviation “PC” means Programmable Controller and is not used as an abbreviation for any­thing else.

the specified ranges.
The

Indicator Color Function

RUN Green Lit when the Analog Input Unit is operating correctly. If operation is not normal, this

indicator turns OFF and Unit operation is stopped.

BROKEN WIRE Red Lit when an input signal wire is disconnected. This indicator operates only when the

input range is set to 1 to 5 V/4 to 20 mA.

Functions The following table briefly outlines the basic functions of the C200H-AD002.

These

functions are covered in more detail in

Function Explanation

Conversion prohibit setting Unnecessary conversion processing time can be reduced by disabling analog-to-digital

conversion for unused inputs. Disabling conversion can also reduce the sampling
period for each input.

Input range setting The input range can be set for each input number according to the input signal level

that is to be used.
Conversion data type setting Sets whether the converted digital output is BCD or binary.
Square root Converts quadratic data, such as thermocouple input, to linear data.
Scaling Converts an analog input signal to a preset range of BCD data for output.
Mean value Sums the sampling data for the specified number of samples, eliminates the minimum

and maximum values, calculates the mean value from the remaining values, and

outputs that value.
Peak value Holds the maximum values for A/D conversion data, scaling data, mean data, and

square root data, and outputs them as output data.
Limit warning The Warning Flag is turned ON if the A/D conversion data, scaling data, mean data, or

square root data exceeds the specified upper- or lower-limit values.
Disconnection detection The Disconnection Detection Flag is turned ON and the BROKEN WIRE indicator is lit if

the input signal wire becomes disconnected when 1 to 5 V/4 to 20 mA are set.
