Frequency Output Connections

The frequency output is used for a remote counter. It can be scaled to out-

put a 1 to 10 kHz signal proportional to mass or volume flow, tempera-

ture, pressure or density.

The frequency output requires a separate 5 to 36 VDC power supply;

however, there are current and power specifications that must be ob-

served. The output can conduct a current up to 40 mA and can dissipate

up to 200 mW. The output is isolated from the meter electronics and pow-

er supply.

Optional Backlight Connection

The loop power meter has an optional backlight connection provided. It is

intended to be powered by a separate 12 to 36 VDC at 35 mA max. power

supply or by the pulse power input. Both options are shown below.
