convert the analog signal to digital value. Also, it refers to
the time taken by an analog output module to convert a
digital value to analog value.
D/A converter Related with the output module, it is used to make
continuous size of analog voltage and current signal
proportionately to the digital value.

Acronym/Term Definition
Linearity error Analog I/O is related between continuous voltage/current
value and digital value, whose agreeable I/O value is
defined as a line within a distance of the minimum 1LSB of
voltage/current. I/O linearity error is regarded as the
declination between the agreeable-converted value and the
actual-converted value on the graph.
Multiplexer A switching circuit where many signals share one A/D
converter or D/A converter.
Analog output module A module with an output circuit to convert analog DC voltage
or current signal proportionate to digital value delivered to
the module from the processor.
Resolution The minimum value recognizable by a measuring
instrument, which is usually displayed in engineering units
(1mV) or the number of bits. In other words, 16383 types of
output are available for 14 bits.
Filter Used to reduce the change in digitally-converted value by
sudden change in the external noise or input for the analog
circuit, through Software and Hardware filters.
Accuracy Displays the maximum declination between agreeable value
and output voltage or current for the whole range of output.
On the other hand, it displays the maximum declination
between agreeable value and digitally-converted input signal
value for the whole range of input. Generally, percentage is
displayed for the full scale. Gain, Offset and Linearity error
are all included in the error type available.
Output accuracy Displays the difference between the actual analog output
voltage/current value and the agreeable-converted value on
the conversion graph for the full scale, with Offset, Gain and
Drift error factors included as well as normal temperature
(25°) and available temperature range displayed,
respectively.

R200 Isolated Analog Output Module 2MLF-DV4S, 2MLF-DC4S User's Guide 17
September 2010 Honeywell
1. Introduction
1.1 Overview of isolated analog output module
The isolated D/A conversion module is used to convert the digital value of signed 16-bit
binary data (data: 14 bits) specified in PLC CPU to analog signal (voltage or current
output).
Voltage output is called as 2MLF-DV4S and current output as 2MLF-DC4S in this
product.
Features of isolated analog output module are as follows:
1. D/A conversion of four channels:
2MLF-DV4S: D/A conversion of four channels (voltage output)
2MLF-DC4S: D/A conversion of four channels (current output)
2. Isolation between channels: The data between channels is processed with high-
reliability.
3. High resolution of 1/16000: Offers a high resolution analog value through the
digital value resolution of 1/16000.
4. High accuracy: High accuracy of ±0.1% or less (when ambient temperature is 25°).
5. Various output range available are:
a) 2MLF-DV4S: 1~5V, 0~5V, 0~10V, -10~10V
b) 2MLF-DC4S: 4~20mA, 0~20mA
6. Output limit setting: Allows the limiting of the digital value range.
7. Rate control setting: Enables the setting of rate or digital value.
8. No limit on the number of modules used on one base: Any number of modules
within the capacity of the power module can be installed on a base.

1.2 Terminology
Analog quantity −A
The following figures depict the conversion of temperature to an analog value of DC
voltage, using a transducer.
Such analog value conversions can be voltage, current, temperature, speed, pressure, and
flow. For example, temperature may continuously change over time as shown in the
figure. Since the changing temperature cannot be directly fed to the PLC, it must be fed
to the PLC by converting to identical analog quantity of DC voltage －10 ~+10V or
current 4~20mA using a transducer.

Digital quantity −D
The following figure displays the digital value.
A discontinuously changing value is called digital value. The Figures displays a digital
value. For example, the digital quantity of 0 and 1 displays On and Off signal. Binary
coded decimal (BCD) and binary value is also a digital value.
This figure displays the process in the PLC.
Analog value cannot be directly fed to the PLC CPU for calculation of the digital value.
The analog value is converted to digital value as in the figure and fed to the CPU. In
addition, in order to output the analog value outward, the CPU’s digital value is
converted to analog value.

Characteristics of D/A conversion
1. Voltage output
The following figure illustrates the characteristic of the D/A conversion (voltage output).
The D/A conversion module is used to convert a digital value from CPU to analog value
for an external device. When the voltage output range of D/A conversion module is -
10~10V, and the input digital value is 0, the output is -10V. If the digital input is 16000,
the output is 10V, where analog value converted from digital input of 1 is equivalent to
1.25mV.
