SA-IN Input Module
Input Circuit Functions
Input expansion – function 9
Expansion
Function 9 assigns the inputs of the function group to the respective other group and takes
function
on their input circuit function. Thus with one input module you can expand function block
A or B in the base module by 8 single-channel or 4 dual-channel sensors with the same
input circuit function (e.g. 8x emergency stop or 4x NC/NO electromagnetic switch.
Function 9 must only be selected for one of the two function groups. Otherwise a device
error will be detected and the FLT LED will flash.

EXAMPLE
Result:
With switch positions 0 to 6 there is an AND link in the base module; for switch positions
7 (OR) and 8 (BYPASS) there is an OR link. For the effects of input module function groups
A and B on the associated base module see page 36.

FUNCTION 6
Function 6B on the base module is expanded by the 4 dual-channel inputs
on the input module
Function 9 (input expansion)
Function 3 (dual-channel with cross-circuit
monitoring and simultaneity monitoring)
Input modules act only on the next base
module to the left, with which they form a
coded system group. The blue digits
designate the set functions.
System 1: INPUT A and INPUT B of the
input module act together with base module
function group AB on the four outputs
(green).
System 2: INPUT A of the input module
acts together with base module function
group A on output group A (blue); INPUT B
acts together with function group B on
output group B (pink).
