4.1 Overview
The specifications for an analog input/output module, the operation, and the programming are
described in this chapter. Analog signals (voltages or currents) are received by four channels on an
analog input/output module, and are converted into 16-bit digital signals. Besides, the analog
input/output module receives two pieces of 16-bit digital data from a CPU module. The digital data
is converted into analog signals (voltages or currents). The analog signals are sent by two channels
on the analog input/output module.
4.1.1 Characteristics
(1) AH06XA-5A, an analog input/output module, is used according to practical application.
CH0~CH3: Inputs received by a channel can be either voltages or currents.
CH4~CH5: Outputs sent by a channel can be either voltages or currents.
(2) High-speed conversion
The conversion speed is 150 μs a channel.
(3) High accuracy
Conversion accuracy: (The ambient temperature is 25°C. The number of output
voltages/currents which are averaged is 100.)
Input: The error is ±0.1% of an input voltage, and ±0.1% of an input current.
Output: The error is ±0.02% of an output voltage, and ±0.06% of an output current.
(4) A scale range can be set by means of software.
Users can set a scale range in ISPSoft. A scale range is a range of digital values to which a
range of analog values corresponds, or a range of digital values corresponding to a range of
analog values.
(5) A module can be set by means of utility software.
HWCONFIG is built-in utility software in ISPSoft. Users can set modes and parameters in
HWCONFIG to complete hardware configuration without spending time writing a program to set
registers corresponding to functions.

circuit/an optocoupler, but the analog channels are not isolated from
one another.
