Note:
If a ground-switching proximity switch is to be connected to a device (eg I / O
box 6753) with positive-switching inputs, this can be done by interposing the
constant current module Type 6753-302 as a "pull up" b 24 V and
the corresponding input (see Fig. 1)
The digital inputs of the compact controller 6942-10 are configured as "posi-
tive switching" by default.
By changing the configuration (see Type 6744-10) each input can be
customized
also be switched to "mass switching".
