Quattro DC Analog Outputs C4 Submenu
Any value over 100% will cause the analog
channel to saturate.
Description
Analog Outputs C4 submenu
With a gain of 1.0 and an offset of 0.0, 10V will
indicate 100% or full value based on
programmed values. For example, with the
above scenario of a gain of 1.0 and an offset of
0.0, a 10V signal an Analog Output set to arm
current would indicate 100% of rated current.
Whereas a 0V signal on the same Analog
Output would indicate 0% of rated current.
