COMPACT RTUS
The compact RTUs can handle up to 2 outputs and 2 digital inputs or alternatively 1 analog
input can be requested in place of the two digital ones.
I/O test
The compact RTU does not have an address
switch; the address is set by communication
using special utility software and a special
communication interface as shown in the
following pictures.
The screen of the utility software includes
additional information about the RTU
including the number of available outputs
and inputs (analog or digital), the pulse
width and amplitude generated for opening
and closing solenoids, special parameters
defining the behavior of the unit in various
cases and tools for testing outputs, inputs,
push buttons, and the buzzer.
