2.3 Description of the inputs<br />
and outputs<br />
<strong>Universal</strong> <strong>Interfaces</strong><br />
<strong>US</strong>/U 2.2, GH Q631 0074 R0111<br />
<strong>US</strong>/U <strong>4.2</strong>, GH Q631 0070 R0111<br />
Grey core: Positive scanning voltage<br />
During operation as an input, the grey core makes the positive, pulsed<br />
scanning voltage available.<br />
Coloured core: Control of the channel<br />
During operation as an input, the status of the contact is read out via the<br />
coloured cores.<br />
During operation as an output, the coloured core makes the positive output<br />
voltage available.<br />
The following table allocates the colours to the channels:<br />
brown Channel A<br />
red<br />
Channel B<br />
orange* Channel C<br />
yellow* Channel D<br />
*only for <strong>US</strong>/U <strong>4.2</strong><br />
Black core: Negative reference potential<br />
During operation as an output, the black core makes the negative reference<br />
potential available.<br />
Important:<br />
The inputs and outputs do not have electrical isolation<br />
to the <strong>EIB</strong> bus voltage (SELV). The SELV criteria only enable<br />
the connection of floating contacts with safety separation.<br />
2.4 Assembly and installation<br />
The device can in mounted in any position. Any cores that are not required<br />
must be insulated.<br />
