YB Modules
The YB module consists of a DH module preconfigured with outputs connected in series.
The output voltage can be adjusted across the range shown in the datasheet by using the
potentiometer situated to the right of the signal connector. Turning the potentiometer clockwise
increases the output voltage.
Signals
The Module Good signal is an isolated (200V from the output) opto-coupler transistor outputs. The maximum
current allowed through the transistor is 1mA. This signal provides an indication that the output is above 90% of
the output set voltage. The transistor is on when the output is “good”.
Module inhibit is an isolated opto-coupler diode input. Passing a minimum of 1mA through the diode will inhibit
(turn off) the output of the module).
