Digital extension modules
There are 4 different extension modules
available for the ALPHA 2, which allow the
controller to be e x tended through addi
-
tional inputs or outputs. The modules are
inserted directly into the ALPHA 2 and
therefore do not take up any additional
space.
The AL2-4EX has the additional feature that
2 inputs may be used as high-speed coun
-
ters with a c ounting frequency of 1 kHz.
All modules feature photocoupler isolation
for all I/Os.

Analog extension modules
The analog extension modules signifi-
cantly increase the range of applications
for the ALPHA 2. With these modules it is
possible to output voltage or current sig-
nals or to measure temperatures.
Three different analog extension modules
are available:
앬
The AL2-2DA offers two additional ana-
log outputs for the ALPHA 2 and con-
verts a digital input value into a voltage
or a current. This module is inserted
directly onto the ALPHA 2.
앬
The AL2-2PT-ADP connects an external
Pt100 sensor to convert temperature
readings into analog signals (0 – 10 V).
앬
The AL2-2TC-ADP connects thermocouple
sensors (K type) to convert temperature
readings into analog signals (0 – 10 V).
