SK Operation with internal control voltage
SK • Operation with external control voltage +24 V)
• Reference point terminal L
a If reference point L is connected with the 0 V
potential of the external voltage source, the
external 24 V potential should be decoupled
through a diode.
SK • Operation with external control voltage from an
electronic device (for example PLC, easy)
• Reference point terminal L
a If reference point L is connected with the 0 V
potential of the external voltage source, the
external 24 V potential should be decoupled
through a diode.
