Power Connections:
The 9825
has an input
rang
e
of
9VDC to 36VDC.
The maximum electrical power
consumption of the 9825 is
6
W
(8W Peak)
.
The
unit is shipped with an external 24VDC linear power supply
and a grounding cable assembly
.
Th
e
GND Terminal should be routed to
the grounding lug on the rear of
the 9825 housing and then to
earth
using the provided grounding cable assembly in order to
optimize
signal stability
.
Use the screw down terminals to secure the power supply leads
and grounding cable
to the 3
position connector in the following configuration:
Pin Assignment:
1 = VDC +
2 = VDC -
3 = GND
Warning:
Verify that the power supply connections are correct before powering on.
Note
:
Make sure that the power cord does not pose a potential obstacle or tripping hazard. Only use
approved accessories and peripherals.
Load Cell
Connections:
The 9825
indicator uses a 6-wire load cell signal connection. This indicator provides a 4.5 volt DC
excitation voltage to the load cell(s). The voltage difference bSIG and -SIG is about 0 ~ 9mV when
connected to a load cell with a 2mV/V output, and about 0 ~ 13.5mV when connected to a load cell with a
3mV/V output. The 9825 indicator can drive up to six (6) 350-ohm load cells (or the equivalent resistance of
all load cells connected in parallel is higher than 87Ω).
If the application requires the 9825 to be connected to multiple load cells, please use a junction box.
Note
:
This product does not contain a junction box. If a junction box is necessary for your application, we
recommend Interface Model JB104SS as an approved accessory.
The
load cell cable requires a shield which must be properly grounded to ensure
maximum stability. High quality cable is recommended. Be sure to route the load cell cable away
from high voltage / power cables.
The maximum length allowed for the load cell or junction box
cable is shown in the following table:
