8.1 Technical data
Detailed technical data can be found in the individual data sheets indicating article
number AC26xx → www.ifm.com.
8.2 Digital stand-alone modules
8.2.1 AC2630 FieldModuleDP 4x2DI M12
The digital module detects the binary control signals at the process level and
transfers them to the higher-level automation device� The signal status is indicated
via LEDs�
The sensors are supplied from the operating voltage U
B
� The load voltage U
L
is not
needed in the input module, but can be used for optional power feed-through�
8.2.2 AC2631 FieldModuleDP 2x2DI 2x2DO M12
This digital I/O module combines 4 digital inputs with an input filter of 3�0 ms and 4
digital 24 V DC outputs in one device�
The outputs are suited for load currents up to 500 mA; the maximum total current
of I
Σ
= 2 A should not be exceeded� The outputs have short-circuit and reverse-
polarity protection�
The signal status can be indicated for each channel via LEDs�
The inputs are located on the upper half of the modules with two inputs on one
socket�
8.3 Analogue input modules
8.3.1 AC2638 FieldModuleDP 4AI (V) M12
The analogue module AC2638 processes signals in the range of -10 V���+10 V� The
voltage is digitalised with a resolution of 16 bit, electrically isolated and transferred
to the higher-level automation device�
The 4 input channels are differential inputs and have a common internal ground
potential� The provided load voltage U
L
(freely selectable up to 30 V DC) is used
to power the connected sensors� Thus it is possible, for example, to power a
measuring potentiometer with 10 V DC from an external voltage source�
In addition, an automatic limit value monitoring is provided�
The module is parameterised via the fieldbus� The parameters are stored
permanently in the module, even in the event of a power failure�
The analogue input signal is measured via a differential input� If the sensor does
not provide two lines for differential measurement (e�g� 24 V, GND and signal),
then GND and input have to be bridged�
