5.8
Signal input or sensor connection (E1, E2)
The unit has two analog inputs: Analog In 1 =
“
E1
”
and Analog In 2 =
“
E2
”
The connection is independent of the programmed operating mode and from the sensor signal
employed.
•
When connecting
aktive
sensors at the terminals
“
E1
”
and
“
GND
”
and or
“
E2
”
and
“
GND
”
attention
must be paid to correct polarity, a 24 V DC power supply is integrated.
•
For sensors in two-wire-technology (4 - 20 mA signal), the connection is made on the
“
E1
”
and
“
24 V
”
or
“
E2
”
and
“
24 V
”
,
“
GND
”
terminal is omitted.
•
When triggering with a PWM signal (10 V) the ratio between the pull-up resistor and the internal
resistance of the open collector output must be considered.
Danger due to electric current
Never apply line voltage to analog inputs!
5.9
Analog output (0 - 10 V)
“

The analogoutputs 0 - 10 V can be allocated with various functions (

It is not permissible to connect outputs of several devices to each other!
5.10
Voltage supply for external devices (+24V, GND)
A voltage supply is integrated for external devices e. g. a sensor (max. current load
technical data).
In case of overload or short circuit (24 V
–
GND), the external power supply is shut down (multi-fuse).
The device performs a
“
Reset
”
and continues operation.
It is not permissible to connect outputs of several devices to each other!

Add-on module type Z-Modul-B Part-No. 380052
The add-on module can be retro
fi
tted as required. This may be necessary when the analog and digital
outputs and inputs are insuf
fi
cient for certain applications. The board is easy to install in the device
and is connected to the printed circuit board (X13) with the plug. The additional outputs and inputs are
programmed in the menu group
“
IO Extension
”
, this appears automatically after the menu group
“
IO
Setup
”
if an add-on module is installed.
Information
The clock module type Z-Module-RTC and the add-on module type Z-MODULE-B both need the slot
|
X13
|
. That means that only one of the two modules can be used!
