4.10.1 ANALOG OUTPUT SETUP
FUG1010GCN provides current, voltage and pulse-rate analog outputs. [Analog Output Setup] allows
you to assign data functions for these signals. The computer’s terminal strip contains the analog output
terminals.
Io (Isolated current) 4 to 20 mA varies in proportion to an assigned data function.
Vo (DC voltage) 0 to 10 Vdc varies in proportion to an assigned data function.
Pgen (TTL logic) 0 to 5000 Hz varies in proportion to an assigned data function.
Digital Pgen* User selective pulses per unit flow.
System 1010 Analog Outputs
*Digital Pgen replaces Pgen in Custody Transfer FUG1010GCCDN flowmeters.
NOTE: For Expanded I/O Modules, refer to drawing 1010N-7-7 and addendum 1010FMA-14 for
details.
Assigning Io Output Functions
The Io analog output is a self-powered, isolated 4-20mA DC signal that varies linearly in relation to a se-
lected data function. Some models feature auxiliary current outputs that are loop powered.
CAUTION: Do not connect self-powered Io outputs to a powered loop.
The flowmeter’s 4-20 mA outputs (except for the Auxiliaries provided in certain A-option models of the
FUG1010GCN flowmeter) provide a “Fault” indication by dropping to approximately 2 mA when the
flowmeter’s primary sensing mechanism is unable to measure the flowrate and fault is declared. This
fault current is generated regardless of the variable currently selected for that output.
*Dual Path meters have the data categories listed above plus characters 1 (Path 1), 2 (Path 2) and S (System).
** See paragraph 4.3 Gas Parameters Menu to set Base Temp F or C.
Vfo Spanned volumetric/mass flow rate
Vfo2 Additional spanned volumetric/mass flow rate
Vfab Spanned unsigned flow magnitude
Vs Spanned liquid sonic velocity
Valc Receive signal amplitude
Vtrb Relative degree of gas turbulence
Vsg Spanned specific gravity
Base S.G. Spanned SG referenced to user temperature**
Viscosity Gas viscosity in centistoke units
T1 Current gas temperature
Iin1, Iin2, Iin3, Iin4 Represents a re-transmit of the analog input signals (e.g., Pressure and
Temp inputs can be transmitted on the 4/20 mA output).
