WIRING CONNECTIONS
Digital Inputs connections
The inputs are grouped together in two sets. CM 1
is the common for 1-4. CM 2 is the common for 5-
8. The must be used with DC voltage onl , 5VDC
-24VDC. The polarit can be either direction, as
long as there is a difference of potential between the
DI and the common, it will register as a closure.
Most of the time the commons are connected
together.
Connecting dr contacts to the digital inputs.
This example uses the 24VDC input terminals to
drive the dr contacts from the field.
Connecting a sourced input.
The common is negative. When positive is applied
to the input, the indicator on the main screen will
darken.
Connecting a sinked input.
The common is positive. When negative is applied
to the input, the indicator on the main screen will
darken.
Connecting the rela output.
This rela is a ver low wattage. It is intended to
bring on an indicator, provide an input to a PLC or
engage a small rela . See specification page 4.
POWER CONNECTIONS
1 AMP at 24VDC is suggested for an external
power suppl . Our plug in suppl is available when
ordering.
