Supply voltage (volts)
One frequency/pulse output (Model 1700 transmitters) or frequency/pulse/discrete output (Model
2700 transmitters):
•Intrinsically safe
•Externally powered (passive)
•Maximum input voltage: 30 VDC, 0.75 watt maximum
•Frequency/pulse output (Model 1700/2700):
-Can be used to indicate either flow rate or total; Model 1700 output reports the same flow variable as the mA output, Model 2700 output is independent from mA output
-Scalable to 10,000 Hz
-Linear with flow rate to 12,500 Hz
-Configurable polarity: active high or active low
-Maximum load limit: see following chart
