two analog grounds labeled AGD.
DI-730 Series Instrument Front Panel
DI-730 Series instruments can accept any eight differential analog inputs within a range of ±10mV to ±1000VDC (or
peak AC). Its ±1000V of channel-to-channel and input-to-output isolation protects delicate control circuits, computer
equipment, and personnel from high common mode voltages.
Use the EXPANSION (USB and PP devices) or Channel Expansion (EN devices) port on the rear of the instrument
with optional CABL-7 (part number 100679) to access the 16 general-purpose (±10V Full Scale) analog inputs. Use
the following diagram for pinout (see also “DI-720, DI-722, and DI-730 Series Instrument Rear Panel” on page 28).
Be sure to read “CAUTION” on page v before connecting signals to the Expansion port of your DI-730 device.
