Signal connection or sensor connection to analog inputs (Analog In 1, Analog In 2)
The unit has 2 analog inputs:
•
E1 Analog In = terminals
“
E1
”
/
“
GND
”
(Analog In 1)
•
E2 Analog In = terminals
“
E2
”
/
“
GND
”
(Analog In 2)
Ensure correct polarity when connecting; a 24 V DC power supply is integrated for sensors. For
sensors in two-wire-technology (4 - 20 mA signal), the connection is made on the
“
+24 V
”
and
“
E1
”
or
“
E2
”
terminals (the GND terminal is omitted). The connection is independent of the programmed
mode and from the sensor signal employed. Place the internal jumper for the external default signal in
the correct position. Factory setting 0 - 10 V (
Jumper for Input signal).
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.
Attention!
Never apply line voltage to analog inputs!

Voltage supply for external devices (+24V, GND)
There is an integrated power supply for external devices, e.g. a sensor. Te24 V, output voltage
tol/- 20%. max. load current
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 expansion module can be retro
fi
tted. This could be necessary if the analog and digital inputs and
outputs are not suf
fi
cient for certain applications. The board is easy to install into the device and is
connected with the control device via a plug. Program the additional inputs and outputs in
