VersaMax Micro PLC Expansion Unit IC200UEX364 accepts forty DC inputs and provides
twenty-four low current (LCDC) transistor outputs. It uses 24Vdc nominal input power.

11.5.1

DC Power

The 24Vdc power source for the Expansion Unit must have enough transient current
capability to support the inrush current of the power supply and to maintain a 24Vdc voltage
level (see power supply specifications for inrush requirements).

11.5.2

DC Inputs

Forty configurable DC inputs can be used as positive or negative logic standard inputs. They
are compatible with a wide range of input devices, such as pushbuttons, limit switches, and
electronic proximity switches.

The Micro PLC Expansion Unit’s +24

Vdc supply can be used for input devices and to power

the DC input circuits at about 8mA per input. The combination of input circuit current and
external device current must not exceed 435mA.

11.5.3

DC Outputs

The Micro PLC Expansion Unit IC200UEX364 has 24 sink-type DC outputs. All outputs are
isolated between field and logic and are switching positive voltage. The outputs have one
common incoming supply (VC) and one common ground (COM). The outputs are able to
drive high inrush currents (8 times the rated current) and are protected against negative
voltage pulses. This makes it possible to switch lamps and inductive loads.

Analog Operation

This  section  explains  how  a  VersaMax  Micro  PLC  Expansion  Unit  with  analog  channels
processes analog data. Unlike discrete expansion units, if one analog unit fails all subsequent
analog  expansion  units  will  stop  communicating.  However,  expansion  units  before  the
failed unit continue to be available.  If an analog expansion fails at power up, no expansion
units (discrete or analog) will be functional.

12.3.1

Analog I/O Parameters

Each analog channel can be configured to operate in either voltage or current mode. If
current mode operation is selected, the range can then be configured as either 4-20mA or
0-20mA. If voltage mode operation is selected (inputs only), the range can then be
configured as either 0-10V or

10V to +10V.

Count Resolution for Analog Expansion Units

For analog expansion units, count resolution is controlled by a DIP switch 6, which is set to
ON by default. If unexpected results are observed, check the position of switch 6. If switch 6
is not ON, power down the system and set switch 6 to ON, as shown in the following figure.
Do NOT change any of the other switches.

12.3.5

Analog Input Processing

The Expansion Unit processes analog input channels with a 12-bit successive-approximation
A/D converter. It converts the analog value into a digital count, calculates the %AI value as
described below, then places the result into the appropriate %AI input reference (these
references are described in Chapter 22:).

Figure 95

Automatic Conversion of Analog Voltage or Current to
Counts

In voltage mode, the Expansion Unit first converts the 0 to 10,000mV input signal to a count
in the range of 0 to 4,000 (or

–

10,000mV to 10,000mV signal to a range of

–

4,000 to 4,000).

The fixed multiplier for this conversion is 2.5.

In current mode, the Expansion Unit first converts the 0 to 20,000µA input signal to a count
value in the range of 0 to 4,000. The fixed multiplier for this conversion is 5. The conversion
for both current modes (0-20mA and 4-20mA) is the same.

Automatic Gain and Offset Adjustment for Analog Inputs

The Expansion Unit then converts the A/D converter's input count value from the range of 0
to 4000 to a final %AI input value in the range of 0 to 32,000. It multiplies the count value by
8 (32000 / 4000) to get the final analog input ($AI):

(input count X 8) = %AI value

Any calculated value above 32,767 is clamped at that maximum value. Any calculated value
less than 0 is clamped at 0.

12.3.6

Analog Output Processing

To generate the analog output signal, the Expansion Unit converts the value in the %AQ
output reference into a count value for the 12-bit D/A converter, which then drives the
analog output.

Figure 96

Automatic Gain and Offset Adjustment for Analog Outputs

The application's %AQ output range of 0 to 32000 corresponds to the D/A converter's
output count range of 0 to 4000. The Expansion Unit first multiplies the %AQ value from the
program by .125 (4000 / 32000) to produce the count value for the D/A converter:

(%AQ X .125) = D/A count

Any calculated value that exceeds 4095 (212-1) is clamped at that maximum value. Any
calculated value less than 0 is clamped at 0. The range 0 to 4095 corresponds to %AQ values
between 0 and 32,767.

Automatic Conversion of Counts to Analog Voltage or
Current

In voltage mode, the D/A converter then converts the count value in the range of 0 to 4,000
counts to an analog signal from 0 to 10,000mV. The output voltage gain (ratio) for this
conversion is 2.5.

In current mode, the D/A converter converts the count value to an analog signal from 0 to
20,000µA. The output current gain for this conversion is 5. The conversion for both current
modes (0-20mA and 4-20mA) is the same.

RTDs per expansion module, four expansion modules per Micro PLC).

Note:

•

RTD Expansion Modules support DOIO for inputs and outputs.

•

If an RTD Expansion module is auto configured with DIP switch 3 OFF (Compatibility Mode), it
reports its identity as a standard analog expansion module (IC200UEX616/626/636). This has
no effect on module operation.

•

For Micro release 4.0 and later, if the RTD Expansion module is auto-configured with DIP switch
3 ON (High-Accuracy Mode), it reports as IC200UEX726/736.
