Analog Inputs

Parent Previous Next

Mobi.Control has 2 analog inputs accessible at terminals 02 / 03 respect to negative at terminal 01.

Software configuration allows to set different parameters of these inputs:

Analog inputs can be configured to work in three mode of operation.

Choose the desired operating mode using the dip-switches [G] in the back of the device.

An NTC temperature sensor measuring in the range -10 to 60°C can be directly connected to analog inputs. Set the dip-switches as shown in figure to enable NTC software linearization.

For long lines use shielded cable, the shield must be connected at terminal 01 only.

Active devices could be powered directly from Mobi.Control when voltage and output are compatible and total current consumption remains within 50mA.

As an example a LM60 from Texas Instruments can be used to measure temperature.
