Function

The ROBA

®

-brake-checker plus DC monitoring module 

is intended for use with an input voltage of 24 VDC. The 

monitoring module monitors the movement of the armature 

disk and emits the determined switching condition via 

control terminal (signal output).
Critical conditions (line breakages, wear, excess temperatu-
re) can be recognised and the respective signal can be emit-
ted via control terminal (error output).

It is possible to select between fast and slow disconnection 
via the input F/S on the control terminal. 

Louder switching noises are generated on the brakes in 
case of fast switch-off than in case of slow switch-off.

The movement detection feature of the armature disk is 
based on the detection of electromagnetic changes in the 
brake. If, due to unfavourable external influences, the secu-
red detection cannot be ensured, it is possible that the 
signal and error outputs do not correspond to the expected 
state (plausibility).
