Figure 7: Setting the binary input threshold voltage
The parameter Input threshold voltage in REX640 is used to set the threshold level of
the binary inputs. Input threshold voltage determines the voltage level for the
activation of the inputs. The threshold can be set for every slot depending on the Slot
specific threshold setting.

Input threshold voltage
The threshold voltage for the relay's binary inputs has to be set according to the used
voltage level. The default value is 16 V DC.
The threshold value should be set in PCM600 according to the selected auxiliary
supply voltage. On the LHMI, the parameter can be found via Configuration/I/O
modules/Common settings/Input threshold Voltage.

Binary outputs

The protection relay provides several binary outputs used for tripping, executing local
or remote-control actions of a breaker or a disconnector, and for connecting the
protection relay to external annunciation equipment for indicating, signalling and
recording.
Power output contacts are used when the current rating requirements of the contacts
are high, for example, for controlling a breaker, such as energizing the breaker trip and
closing coils.
