For hazardous applications, the following must be met:
Uo ≤ Ui
Io ≤ Ii
Po ≤ Pi
Co ≥ Ci + Ct
Lo ≥ Li + Lt
Uo/Io/Po/Co/Lo are IS barrier output parameters;
Ui/Ii/Pi/Ci/Li are RigRat input parameters;
Ct/Lt are extension cable additional parameters.
RigRat switch port IS parameters:
Ui=30V
Ii= 100mA
Pi=0.75W
Ci=0nF.
Li=0uH
