7.1 Features and Functions
Construction
The digital output modules handle a nominal current of 0.5 A or 2 A.
The output signals are electrically isolated from the process signals via opto-
couplers. Each output module is assigned a light emitting diode for signal
status display:
D LED illuminated: HIGH
D LED extinguished: LOW
When cycling power ON and OFF, and/or in the event of a failure of the cen-
tral processing unit, the digital outputs are switched to logical 0 state (LOW =
secure status).
