Signal conditioning
The D3PC is equipped with eight built-in analog inputs, with these signal input capabilities:
 Selectable voltage / IEPE mode
 Selectable constant current excitation (IEPE mode), 4 or 8 mA
 Constant current excitation compliance up to 24 VDC
 Differential or single-ended input mode (software selectable)
 Voltage input mode with ranges ±10, ±2, ±0.5 or ±0.1 V
 Selectable DC or AC coupling, high-pass 0.16 or 3.4 Hz
 High-pass lter selectable between 0.16 or 3.4 Hz (when AC coupling is engaged)
 30V over-voltage input protection
 All channels can be set completely independently`
A/D card
The D3PC includes the ORION-0824-200 A/D card as standard. This card provides these digitization capa-
bilities:
 8 simultaneously sampled analog input channels
 24-bit resolution, separate ADC per channels
 Sigma-delta ADC converter for each channel
 204.8 kS/s/ch maximum sample rate (all channels simultaneously)
 Powerful anti-aliasing ltering is standard and automatically adjusts to the selected sample rate
 Crosstalk 114 dB
 2 synchronous counter/encoder inputs
 8 each digital input and output lines
The A/D card can be upgraded to have several options installed on it, including
 UP-ORION-CAN2 Adds two high-speed synchronous CAN BUS interfaces to the system, including
mounting the connectors on the front panel, and installing the DS-OPT-CAN software support for CAN
 UP-ORION-CTR8 Adds 8 additional counters, which have adjustable threshold levels, and higher
input voltage capabilities. In addition, each counter can handle any measurement type without needing a
second counter in a “pair.” Thus, 8 separate quadrature encoders could be input. Due to space limita-
tions on the D3PC chassis, it is recommended to also purchase the external break-out box when the
counter expansion is ordered.
