of outputs
2.1 Current output I
• The current output is galvanically isolated from all input and output circuits.
• Typical current output
approx. 15 V DC positive

= 15 V DC
I = 23 mA when operated without receiver instruments at the current output
I = 3 mA when operated with receiver instruments at the current output
• Connection diagrams, see Sect. 2.3.
2.2 Pulse output P and status
output S
• The pulse and status outputs are galvanically isolated from the current output and all input circuits.
• Typical pulse and status outputs B1

output
• The pulse and status outputs can be operated in the active or passive mode.
Active mode:
The current output is the internal voltage source, connection of electronic totalizers
Passive mode:
External DC or AC voltage source required, connection of electronic or
electromechanical totalizers
Digital pulse division, interpulse period is non-uniform. Therefore, if frequency meters or cycle counters are
connected, allow for minimum counting interval:
