3.1 Inputs and outputs
The degree of modulation can be controlled via a control signal, which is connec-
ted to the input of the analogue module EM3/3.
The current degree of modulation can be signalled via an output from the analogue
module EM3/3.
3.1.1 Input
The analogue module EM3/3 has an analogue input.
The input can be set for the following ranges using a DIP switch:
current input 0…20mA or 4…20mA, depending on the range set,
voltage input 0…10V or 2…10V, depending on the range set.
