Discrete output (Model 2700 only):
- Can report event 1, event 2, event 1 or 2, flow direction, flow switch, calibration in
progress, or fault
- Configurable polarity: active high or active low
Model 2700 transmitters with non-intrinsically safe configurable input/outputs option board
(output option code B or C)
One or two 4–20 mA outputs:
Channel A is always an mA output; Channel B is configurable as an mA output
Not intrinsically safe
Internally powered (active)
Isolated to ±50 VDC from all other outputs and earth ground
Maximum load limit:
- Channel A (mA1): 820 Ohms
- Channel B (mA2): 420 Ohms
Can report mass flow, volume flow, density, temperature, or drive gain; transmitters with the
petroleum measurement application (API) or enhanced density application can also report
standard volume flow and density at reference temperature
Linear with process from 3.8 to 20.5 mA, per NAMUR NE43 (June 1994)
