About the interface cards
4.4.2 General
The interface IF-A1 is an analogue interface with galvani-
cally isolated, customisable, analogue and digital inputs and
outputs. Visualisation:
IF-A1
Netzgeräteseite
Ein/Ausgänge
PSU side
Customisable means, that you can customise these inputs
and outputs to your needs, but always within a voltage ran-
ge of 0...10V. At devices with two extension card slots (eg.
PSI9000) it is possible to combine the IF-A1 with a digital
interface card (eg. IF-U1 (USB)), in order to control, for ex-
ample, the device by USB and put out actual values via the
analogue outputs of the analogue card. Or vice versa, you
control the device by analogue set values and read out and
log the actual values to a PC via RS3, CAN or USB.
Generally applies: all monitoring and surveillance features
are permanently active, even if two card (one digital, one
analogue) are equipped. Only the control of the device with
set values requires the activation of the external mode (IF-
A1) resp. of the remote mode (digital interfaces), whereas
the remote mode (control by a digital interface card)
has priority. In case the device is in control by the analogue
interface (external mode, indicated in the display by
tern) and the control of the device via a digital interface is
activated, the device will switch to remote mode (indicated
in the display by
remote).
4.4.3 Configuring the IF-A1
The interface is configured in the communication menu:

Name of 1st interface card (if equipped)
Slot B : { IF-… }

Here you can see an overview of the equipped cards.
With:

Following parameters can be set:
Analogue inputs
Analogue set values are only accepted by the device if it is
in external mode (indicated in the display by
The analogue interface IF-A1 has three analogue inputs
with these features:
AI1: PSEL (external set value for power) or RSEL (external
set value for inner resistance, optional with unlocked
U/I/R operation)
© 009, Elektro-Automatik GmbH & Co. KG
AI: CSEL (external set value for current)
AI3: VSEL (external set value for voltage)
The minimum and maximum input voltage can be preset.
The analogue inputs can be adapted the input signal this
way. By limitting the standard voltage range of 0...10V to
a lower value the resolution is also lowered. Example: if
the voltage range is set to 1V difference between U

The adjusted voltage range, for example .00V...8.00V, cor-
responds to 0...100% set value. A higher or lower voltage is
treated as either U

Analogue outputs
The actual values of output voltage, current and power are
ex-
led out to the analogue outputs. These outputs can be ad-
apted to custom requirements. The first value stands for U
(minimum output voltage), the second for U
output voltage). It applies:
U

By limitting the standard voltage range of 0...10V to a lower
value the resolution is also lowered. Example: if the voltage
range is set to 1V difference between U
and accuracy will be reduced by the factor 10.
The reference voltage is an exception. It can be set to a
value between 1V and 10V.
