A8 Ratio Station (Templates 16 and 17)
The Ratio Station provides a set point for a subsequent slave controller. The wild variable is weighted by ratio (
rAtO
) and bias (
bIAS
) values and
is then retransmitted as an analog output value. The ratio value applied to the wild variable can be either a local value set o
n the front panel or a remote
signal on an analog input.
The actual ratio of the process variable to the wild variable is also displayed.
