Inputs
• All DC Analog Card options are available with 16 inputs.
• The inputs may be voltage or current.
• With the exception of the 517-0478 and 517-0479 cards that use adapter
modules, there are no on-board option jumpers; each option requires a different
card.

Shielding
All inputs should have shield connected at source of signal. Shields can
alternately be connected to the auxiliary ground on D25 power supply
terminal block. DO NOT ground at both ends of cable.
