19. EXCITATION OUTPUTS
Jumpers in upper right
Jumpers b, c, d, e, f in the upper right of the power supply board allow selection of one of
three available transducer excitation outputs. These are isolated to 50 Vdc from signal
common, to 250 Vac from power, and to 2 kV from meter output options. The same jumper
locations apply to the universal AC power supply (85-264 Vac) and to the low voltage power
supply (12-32 Vac or 10-48 Vdc). When these jumpers are not installed, an external reference
voltage up to 20 Vdc can be applied to the meter for ratiometric operation.

Jumpers in lower left
Jumpers a, h, g in the lower left of the power supply board provide special features when
installed:
Jumper a Front panel menus are locked out when installed. See Section 9.
Jumper h Connects "Control Input 2" to P1-4 when installed.
Jumper g Provides non-is5 Vdc, 30 mA power output at P1-4 when installed.
This power is in addition to the isolated excitation output set by jumpers in the
upper right of the board.
