3.2 Intended Use
The VBA-2E-G11-I/U/PT100-* is an analog module for connecting 0 V ... 10 V or 0/4 mA ... 20
mA measurement sensors and Pt100 sensors to the AS-Interface network. Measured values
are converted and data transmitted asynchronously as defined by AS-Interface profile 7.3. The
measured values are converted internally at a resolution of 16 bits. The analog module features
two analog inputs which can be current input, voltage input, or resistance therm ometer input.
The measurement sensors are powered either by the AS-Interface or by the auxiliary power
source.
Read through these instructions thoroughly. Familiarize yourself with the device before
installing, mounting, or operating.
Always operate the device as described in these instructions to ensure that the device and
connected systems function correctly. The protection of operating personnel and plant is only
guaranteed if the device is operated in accordance with its intended use.
3.3 General Safety Instructions
Only instructed specialist staff may operate the device in accordance with the operating
manual.
User modification and or repair are dangerous and will void the warranty and exclude the
manufacturer from any liability. If serious faults occur, stop using the device. Secure the device
against inadvertent operation. In the event of repairs, return the device to your local
Pepperl+Fuchs representative or sales office.
The connection of the device and maintenance work when live may only be carried out by a
qualified electrical specialist.
The operating company bears responsibility for observing locally applicable safety regulations.
Store the not used device in the original packaging. This offers the device optimal protection
against impact and moisture.
Ensure that the ambient conditions comply with regulations.
Danger!
This symbol indicates an imminent danger.
Non-observance will result in personal injury or death.
Warning!
This symbol indicates a possible fault or danger.
Non-observance may cause personal injury or serious property damage.
Caution!
This symbol indicates a possible fault.
Non-observance could interrupt devices and any connected facilities or systems, or result in
their complete failure.

4.3 Automatic Detection of the Sensor Type
The VBA-2E-G11-I/U/PT100-* analog input module automatically detects which sensor type is
connected. The types of sensors that can be connected are: 0 V ... 10 V measurement
sensors, 0/4 mA ... 20 mA-measurement sensors, or Pt100 temperature sensors. The sensor
type is automatically detected once switched on. Once the module has detected the sensor
type, the corresponding module configuration is activated.
All input LEDs are illuminated during the first few seconds after switching on. During this time,
the module evaluates the connected sensor type on the basis of various measured values. The
signal values that ensure unambiguous detection of the type of sensor connected are:
■ Voltage: 1 V ... 11.5 V
■ Current: 1 mA ... 23 mA
■ Pt100: -219 °C ... 884 °C
If the module cannot clearly establish which sensor type is connected, the last detected sensor
type is provisionally activated. For example, the module may not detect which sensor type is
connected if the signal values are not within the specified thresholds or if two different sensor
types are simultaneously applied to one channel.
A specific sensor type is finally activated when the signal values measured are within the
specified thresholds.
Note!
Switching Off the Second Channel
Figure 4.4 Input PT2 bridge
Two bridges are plugged in at the PT100 input PT2 by default; these bridges are designed to
switch off channel 2. Remove the bridges to use channels 1 and 2.
The bridges must be plugged in and disconnected only when the module is de-energized!

Note!
The Pt100 Input Is an Exception:
The Pt100 sensor type is only activated if a Pt100 temperature sensor is connected to the
PT100 inputs before switching on. The Pt100 sensor type cannot be activated during operation
or activated provisionally.
Note!
If you connect two different sensor types to one channel simultaneously, fault-free operation is
not guaranteed. The module will not be damaged by this.

Product Description
4.4 Pt100 temperature sensor
Pt100 temperature sensors are platinum resistance thermometers complying with standard
IEC 751 / DIN EN 60751. In this standard, various values of the temperature sensor are
defined. The nominal resistance of the Pt100 is 100 , measured at 0 °C. Furthermore, as well
as other values, the mean temperature coefficient of 0°C to 100 °C is also defined. The mean
temperature coefficient defines the mean change in resistance relative to the nominal
resistance. The analog module calculates the corresponding temperature based on the
measured resistance of the temperature sensor.
