Introducing the CIO-DAS48-I
Overview: CIO-DAS48-I features
The CIO-DAS48-I is a CIO-DAS48-PGA board with six SIP resistors installed. These resistors convert the
voltage inputs on the CIO-DAS48-PGA to current inputs.
The CIO-DAS48-I provides 24 current inputs. The input mode is switch-selectable. Input ranges are software-
selectable for 4-20 mA, 2-10 mA, 1-5 mA, or 0.5-2.5 mA.
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.
