Introducing the CIO-DAS48-PGA
Overview: CIO-DAS48-PGA features
The CIO-DAS48-PGA provides 48 single-ended analog inputs or 24 differential inputs. The input mode is
switch-selectable. Input ranges are software-selectable as either bipolar or unipolar:
 Bipolar: ±10 V, ±5 V, ±2.5 V, ±1.25 V, and ±0.625 V
 Unipolar: 0 to 10 V, 0 to 5 V, 0 to 2.5 V, and 0 to 1.25 V
In differential mode, up to three optional 10 K SIPs can be installed to provide ground reference to the CH LO
inputs. The SIPs are installed in banks of 8 inputs each.
An optional current measurement conversion kit (MCC part number CIO-DAS48-ISIP) is available for
converting the 24 differential voltage measurements inputs into 24 current measurement inputs. The kit
contains six, four-resistor-SIPs that you install on the board. You set the board's input type to current with an
on-board jumper.
A DC/DC converter supplies stable ±15 V power to the analog circuitry. It is possible to construct the board
without the DC/DC converter. This reduces the cost but limits the ranges of analog inputs. It is available with
orders of 10 or more units.
You can enable a wait state generator with an on-board jumper.
