internal power. This
terminal can supply
up to approximately
2.5 mA, continuously, to external circuitry. Typical load /line regulation
under ordinary conditions is about ± 10%.
LOCAL COM: Local Common
0-5 V OUT: 0 to 5 volt Voltage Output. Frequency to Analog Output.
PULSE OUT: Pulse-Out Frequency Output Signal. It is an "open-collec-
tor" output (also known as "n-p-n" or "current-sinking"), referenced to
transmitter Local-Common.
LOOP (–): 4 to 20 mA Current Loop – current into transmitter
LOOP (+): 4 to 20 mA Current Loop – current out of transmitter
Input: Turbine Mounted Display or Conditioned Signal Sensor (Open Collector)
Output: Customer Equipment, 0-20 mA Sensing, Built-in Loop Power Supply
