2.0 Product overview
2.1 General product information
The DR4088xx is a feedback module that can be connected to the central unit via the S88(N)®.
The DR4088
-
xx has 16 feedback inputs.
The DR4088xx is available as CS version (current sensor 2
-
wire track), as OPTO version (connection of reed contacts, 3
-
wire track signal to track ground) and as
GND version (3
-
wire track).
2.2 Technical specifications
The connection terminals of the 16 feedback units are designed for a cross
-
section of 0.5mm², the two terminals for "C" are designed for a cross
-
section of
0.75mm².

Important
! DR4088GND 3
-
wire operation:
Due to the H
-
bridge (track output) in the DR50xx, feedback devices in the DR4088GND version must not be used against track ground, as
is usually the case with 3
-
wire tracks. This inevitably leads to the destruction of the DR50xx.
If a 3
-
wire driver still wants to drive with the DR50xx and report back against track ground, the DR4088OPTO
can be used.
