2.1 General product informaon
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 (connecon of reed contacts, 3-wire track signal to track ground) and as
GND version (3-wire track).
2.2 Technical specicaons
The connecon terminals of the 16 feedback units are designed for a cross-secon of 0.5mm², the two terminals for "C" are designed for a cross-secon of
0.75mm².

Important! DR4088GND 3-wire operaon:
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 destrucon of the DR50xx.
If a 3-wire driver sll wants to drive with the DR50xx and report back against track ground, the DR4088OPTO
can be used.
