Function mode 5 – 1oo2 (equivalent)
Signal evaluation of a sensor (typically OSSD) that switches
both signals of a channel pair simultaneously.
The sensor can monitor for short circuits and for cross-circuit­
ing.
A two-channel sensor (internally equivalent) per channel
pair with standard unswitched sensor power supply. T0, T2,
T4, T6 run in this function mode on static 24 V DC.
