Figure B-3. Locations of PK2100 Headers and Jumpers
The jumper configurations are described in Table B-2, Table B-3, and
Table B-4..
Table B-2. PK2100 Header Descriptions
Header Description
H1
When H1 is connected, a 10 k excitation resistor, RP6A, is
connected between the +10 V reference and the high-gain
input AD+.
H7
Connect a jumper across H7 to cause differential inputs AD+
and AD– to be balanced in gain. If the jumper is discon-
nected, the gain is greater on the AD+ side, so that if both
inputs are set to 5 V, the output of the operational amplifier is
5 V. Use this feature to accept input from bridges where the
taps are nominally at +5 V.
H9
A jumper across H9 connects the internal battery to relay 1
N.O. contact. Use H9 when a battery self-test circuit is to be
implemented by connecting a switched load to the battery.
H11 A jumper is normally installed across H11 to connect K to the
+24 V power supply. Disconnect only if a separate power
supply is to be used for high-current outputs O1–O7. In that
case,
K must be connected to that power supply.
J7 Connect 2-3 on J7 for voltage output on the DAC channel
(factory setting). Connect 1-2 for 20 mA current output.
