Product Description
3 Product Description
3.1 Intended Use
The VBA-4 -K 5-IL is an analog module for connecting up to four sensors 0/4 ... 20 mA to the
AS-Interface network. Data conversion and data transfer are provided asynchronously
according to AS-Interface profile 7.3. The data is converted internally at a 16 bit resolution. The
analog module features four analog current inputs. Power is supplied to the sensors by the
auxiliary voltage.
3.2 Displays and Operating lements

3.4 Automatic Activation of Input Channels
All input channels are deactivated by default. Wire break detection is activated (parameter bit
P3 = 1). The measuring range is 4 mA ... 20 mA. The analog module checks the input signals
to detect and automatically activate the connected inputs. This state is indicated by the four
yellow L Ds IN1 ... IN4 illuminating in sequence until at least one connected input is detected.
If no connected input is detected, the peripheral fault is set after 5 seconds. Automatic
activation is still possible.
Activating an Input Channel
An input channel is activated if an input signal within a range of 1 mA ... 23 mA is present. Any
activated inputs remain active after the module is restarted. The sequence and number of
activated inputs can be chosen as required. To use the automatic activation, no jumpers may
be installed between GND and 1CH, 2CH, or 3CH.

Note!
If wire break detection is disabled (parameter bit P3 = 0), automatic activation is switched off
and all four input channels are activated. The measuring range is 0 mA ... 20 mA. The number
of active input channels can be set by activating them manually using a jumper between GND
and 1CH, 2CH, or 3CH. See chapter 3.6.

Product Description
3.5 Resetting the Automatically Detected Sensor Types
Any sensor types saved through automatic detection are reset when the input configuration of
the module is manually changed. For this, there are two available options:
1. Switch off the module power supply. Place or remove the jumper between 1CH, 2CH, or
3CH, and GND, then switch on the supply voltage again.
2. Change the status of parameter P3 (see chapter 5.3). In this case, it is not necessary to
switch the supply voltage off and on.
Repeat this process if necessary to return to the required input configuration.
3.6 Manual Activation of the Input Channels
The number of active input channels can be determined using a jumper between the GND and
1CH, 2CH, and 3CH terminals.
Note!
Any change made to the input configuration via a jumper between 1CH, 2CH, or 3CH, and
GND is only detected once the supply voltage is switched on. Changes made via parameter P1
can also be implemented during ongoing operation. See chapter 5.3.
Do not connect the 1CH, 2CH, 3CH, and GND connections to external potentials. The length of
the jumpers must not exceed 5 cm.

P3 = 1). See chapter 3.4 and see chapter 5.3.

4 Installation
4.1 Storage and Transport
For storage and transport purposes, package the unit using shockproof packaging material
and protect it against moisture. The best method of protection is to package the unit using the
original packaging. Furthermore, ensure that the ambient conditions are within allowable range.
4.2 Unpacking
Check the product for damage while unpacking. In the event of damage to the product, inform
the post office or parcel service and notify the supplier.
Retain the original packaging in case the device must be stored or shipped again at a later
date.
Should you have any questions, please contact Pepperl+Fuchs.
4.3 Mounting
Mount the module by snapping it onto a 35 mm DIN rail in compliance with N 50022.
nlocking Terminal Blocks
Proceed as follows to unlock and eject terminal blocks:
Figure 4.1 Unlocking terminals
4.4 AS-Interface/Auxiliary Voltage Connection
Two terminals are always available for ASI+, ASI-, AUX+, and AUX- to make it easier to loop the
leads through. ach of these pairs of terminals is bridged in the terminal block. This ensures
the connection is retained even if the terminal block is disconnected from the module.
1. Lift the label carrier upwards.
2. Guide a suitable screwdriver through the eye on the ejector and then:
■ Insert the blade of the screwdriver on the bottom of the foot bolt.
■ Then pull on the handle of the screwdriver in the direction indicated.
3. Remove the terminal block.
