24 tinb29e1-c (2019-10) VGC083A_B.om
The VGC083 requires an input power of 20 … 28 V (dc), 200 W to operate. One
each 2-contact pluggable terminal strip mating connector is provided for connection
to the power contactors. Optional power supplies are also available from INFICON
(PN → 85).

A total of six setpoint relays are provided by the VGC083. Two each 9-contact
pluggable terminal strip mating connectors are provided for easy connection to the
relay contactors. The VGC083 back panel relay connectors are marked RLY1 thru
RLY6. Each relay has a contact labeled = (Normally Open), ≠ (Normally Closed)
and I (common).

A total of three analog outputs are provided by the VGC083. These output voltage
signals are proportional to the displayed pressure for any of the user assigned
vacuum gauges. Three each 2-contact pluggable terminal strip mating connectors
are provided for connection to the analog output contactors. The VGC083 back
panel analog output connectors are marked AO1, AO2 and AO3. Each connector
has a contact labeled + (analog output signal) and – (analog output ground).

One analog input is provided by the VGC083 for using as an alternate gauge to "2".
This input can be accepted from one capacitance diaphragm gauge or other
INFICON vacuum module series PGE300, PGE500 or BAG302. One each 3-con-
tact mating pluggable terminal strip connector is provided for connection to the
analog input contactor. The VGC083 back panel analog input connector is marked
A1. Each connector has a contact labeled + (analog input signal) and – (analog
input ground) and D (power detect).
