17. EXCITATION OUTPUT & POWER SUPPLY

Three isolated transducer excitation output levels are available from the power supply

board. These are selectable via jumpers b, c, d, e, f in the upper right of the board, as

illustrated. In addition, the board provides three jumper positions for special features. The

same jumper locations apply to the universal power supply (85-264 Vac or 90-300 Vdc) and

to the low voltage power supply (12-32 Vac or 10-48 Vdc).

1. Letters indicate jumper position. Jumpers are installed on pins adjacent to letters.
