Pulse Output Connections
The pulse output is used for a remote counter. When the preset volume or
mass (defined in the totalizer settings, see page 3-10) has passed the me-
ter, the output provides a 50 millisecond square pulse.
The pulse output requires a separate 5 to 36 VDC power supply. The
pulse output optical relay is a normally-open single-pole relay. The relay
has a nominal 200 volt/160 ohm rating. This means that it has a nominal
on-resistance of 160 ohms, and the largest voltage that it can withstand
across the output terminals is 200 volts. However, there are current and
power specifications that must be observed. The relay can conduct a cur-
rent up to 40 mA and can dissipate up to 320 mW. The relay output is iso-
lated from the meter electronics and power supply.
