Note:
1. AF-10MR-D, AF-10MT-GD, AF-20MR-D and AF-20MT-GD can all receive analogue inputs
through all input interfaces (I1-I6 or I1-I12). They are automatically set to analogue or digital
input. An analogue signal is recognised when the input terminal is connected to the AN function
block. It is important to set analogue inputs first when using SCADA software.
2. The analogue input requires 0V ~ +10V voltage signals and is divided equally in 0.1V increment
steps. When programming, all the block parameters related to analogue are based on the minimum
precision of class 1.
3. All inputs over 10.0V are recognised as digital inputs.
4. Digital inputs:
