d) Using a 0-5VDC Output Power Adapter Package.
An optional 0-5VDC Output Power Adapter Package is available for use
with the TFP Series.
The 0-5VDC Output Power Adapter Package consists of a power source
(115VAC or 230VAC) and cable assembly with pig-tail (soldered wire)
ends for the signal output. This should be assembled as shown in the
following diagram.
Connecting the Power Adapter to the Flow Sensor
(All other models similar)
Electrical connections to the cable assembly should be made as follows:
YELLOW WIRE
: This provides the 0-5VDC signal output and should be
connected to the positive terminal of the display, data acquisition system or
voltmeter with an impedance of greater than 2500
Ω (Ohms).
GREEN WIRE
: This is not used.
WHITE WIRE:
This is the signal negative and should be connected to the
negative (ground) terminal of the voltmeter, display or data acquisition
system.
CAUTION: Avoid high voltage static discharges to any of the
connections. Do not short the output signal wires or allow them to
contact the power wires at any time. DAMAGE WILL RESULT!
