S0 Pulse Outputs - DDS & DTS Series Kilowatt Hour Meters
The DDS-1Y-18L-40A, DDS-1Y-36L-80A-M & DTS-353-100A-M have S0 pulse outputs which conform to the DIN standard 43864. S0 pulse outputs can be used in a current sink NPN configuration or a current source PNP configuration.
The requirements of this standard are as follows:
  • Maximum output voltage 27V
  • Maximum output current 27mA
  • Minimum drive current >10mA into 800 Ohms
  • On status level >2.2mA
Below is a typical S0 pulse output circuit for these meters, showing both NPN & PNP applications.
