Pulse Output Connections
The pulse output is used for a remote counter of the flow total. When the pre-
set volume or mass (defined in the totalizer settings, see page 3-9) has passed
the meter, 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 can con-
duct a current up to 40 mA. It is isolated from the meter electronics and
power supply.

Frequency Output Connections
The frequency output is used for a remote counter of the flow rate. It can be
scaled to output a 1 to 10 kHz signal proportional to mass or volume flow,
temperature, or density.
The frequency output requires a separate 5 to 36 VDC power supply. The
frequency output optical relay is a normally-open single-pole relay. The out-
put can conduct a current up to 40 mA. It is isolated from the meter electron-
ics and power supply.
