Configuration of the inputs and outputs for the measuring range switch-over
and feedback signals
In the example shown in the figure, the following inputs and outputs are
assigned to Uras26 detector 1 (see yellow marking):
• The analog output X20-AO1 for output of the measured values ("Iout")
• The digital input X22-DI4 for external control of the measuring range
switch-over ("MR Control"),
• The digital output X22-DO4 for the measuring range feedback signal
("MR Feedback").
Mode of functioning of the digital inputs and outputs for the
measuring range switch-over and feedback
Active range Switching state Digital input Digital output
