INPUTS
MAIN INPUT
The advanced Solid State Relays have 1 main input to control, to which you can connect, linear sensors in voltage or current
to acquire process variable (PV) values
To configure, you always have to define the type of probe or sensor (tYP), the maximum and minimum scale limit (Hi.S – Lo.S)
for the process variable value,.
There is a parameter to correct the offset of the input signal (oF.S): the set value is algebraically added to the read of
the process variable.
If noise on the main input causes instability of the acquired value, you can reduce its effect by setting a low pass
digital filter (Flt). The default setting of 0.1sec is usually sufficient.

Example 1:
VIN = 0…10V
tyP. = 1
Lo.S = 0.0
HI.S = 100.0
The default values (Lo.S = 0.0 and HI.S = 100.0) can be changed to obtain the required scale of the PV in engineering value
corresponding to the minimum and maximum of the physical input (V/mA).
In automatic mode, the engineering value (PV) is attributed to power Ou.P for values between 0.0 and 100.0.
