Analog expansion module IT-1601
The IT-1601 expansion module has 8 analog inputs with common pole and 2 analog outputs with
common pole. The inputs are universal, configurable independently of each other as voltage, current
inputs, two-wire connection of passive resistance sensors. The resolution is 16 bit, the module ensures
processing of the measured value, conversion to engineering units, etc. The analog outputs have a
resolution of 10 bit, voltage 0÷10V. The analog inputs and outputs are galvanically isolated from the
internal circuits and the status of each input is indicated on the module panel.
