WebJun 11, 2024 · So, input sources (previous stages) should be controlled voltage sources producing voltage with two possible values - HIGH and ZERO. In both cases, the source output resistance has to be zero; so ZERO means both zero voltage and zero resistance. This will ensure that we apply the desired voltage to the gate input. WebTo elaborate on @AltAir's comment, the Micro820 controller you have has 12 inputs, 4 of which (I-00 - I-03) can be used as either 0-10v analog inputs or 24VDC digital inputs. There are a few considerations: Unlike the other digital inputs (I-04 - I-11), the shared digital/analog inputs are not isolated from the controller's power supply.

Active sensors can also produce signal amplification. A good example of an active sensor is an LVDT sensor or a strain gauge.

WebDigital input (DI) modules continually scan their input points for the presence or absence of voltage. If voltage is present, a 1 is written to a memory location. If voltage is absent, a 0 is written there. The required voltage type and magnitude are two of the factors that distinguish one DI module from another.
