SA-IN Input Module
Input Circuit Functions
Standard functions 1 to 6
Standard
Functions 1 to 6 allow input expansion for standard functions such as emergency stop,
functions
light curtain, valve position monitoring, etc. The signals are AND-linked with the base
module function blocks. The configuration of input terminals I1 to I4 (function group A)
and I5 to I8 (function group B) can be set separately. In switch position 0 unused inputs do
not need to be connected. In all other switch positions any unused inputs must be
connected in such a way as to correspond to the indicated good state of the selected input
circuit function of the respective function group on the input module.
linked inputs. The exception is function 1, where all inputs are AND-linked. See also
