3.9 Function of the digital inputs and outputs
SENTRON PAC4200 has:
● Two multifunctional integral digital inputs
● Two multifunctional integral digital outputs
● Optionally up to 8 plug-in digital inputs
● Optionally up to 4 plug-in digital outputs
Functions of the digital outputs
The following functions can be assigned to the digital outputs:
● Energy pulse output, programmable for active or reactive energy
● Signaling the direction of rotation
● Displaying the operating status of SENTRON PAC4200
● Signaling limit violations
● Switching output, remote controlled via the communication interfaces
● Output of the end of a subperiod for synchronizing other devices
Signal output
The digital output supplies a number of pulses or edges proportional to the energy
measured.
